A layer of sedimentary rock is laid down on top of the igneous bedrock, usually as a result of an area being covered by prehistoric seas. The hard body parts of dead sea animals, along with precipitates from seawater and sediments from the land, fall to the sea floor and are changed to stone by extreme pressure and the resulting temperature. What sort of sediments collect vary with the depth and location. Calcium, magnesium and dissolved silicates are more common in deeper water, with silt, mud and sand more common toward the prehistoric shore. Quantities of sediment and ancient sea currents also determine the depth and shape of these deposits. Sedimentary rock is a continuum of types (because they are physical mixtures), with mudstones, shales, sandstones, limestones, dolomites and chert often grading into one another. Dolomite is a sedimentary rock. Geologists think it forms in two ways - either by direct precipitation from solution, or a replacement after limestone. After a limestone is formed, it is then subjected to magnesium rich waters at depth (perhaps by reimmersion in sea water) with the heat and pressure recrystallizing the rock, changing its chemical structure, changing it to dolomite. This recrystallization eliminates most fossils, except those already preserved by chert. Because most of the characteristics of the rock remain similar (hardness, color, etc.) it is not considered a metamorphic rock.

Home Info Membership Convention ... GIS HOT TOPICS NEW: Index to Karst Geoscience Programs at US Universities GIS Special Interest Group Welcome to the web page of the National Speleological Society's (NSS) Section of Cave Geology and Geography. The Section is the oldest in the NSS, and since 1968 has generally functioned as a forum for the exchange of cave geoscience information and the interaction of karst geoscientists. It also serves as the NSS's link to the American Geological Institute . This is not to say that non-geoscientists or non-degreed persons are not welcome. In fact, it's just the opposite. Cave science is largely based on the explorations and observations of cavers (which describes most degreed Section members when you strip away the degrees) and other folks who often have a strong interest in the geosciences and make many and substantive contributions. This aspect of caving/cave science makes the Section a group that has the degrees and does the related "big science," yet is just as comfortable with low key science, interdisciplinary science, and cave science education. The Section is active in several ways, and is picking up steam. For example:

Cave Geology Photo Index Traditionally, the science of geology involves the study of the rocks of the earth's surface. The age of the rocks can be found by examining the fossils embedded within them. The composition can be studied by physical and chemical analysis, such as their hardness, brittleness, and whether they dissolve in acid or not. Caves can contribute to the study of surface rocks by providing access to the underground environment, often uncluttered by the physical limitations on the surface, such as plants, soil, and weathering. More interesting to cavers, however, is the study of the cave itself: the void in the rock through which we travel. Forget how old the rock is - when did the cave itself form? How long did it take? Why is it shaped the way it is? Where is the best place to dig to find more passageways? There are three major types of caves that are popular with explorers: solution caves, lava tubes, and boulder piles. Solution caves are formed in areas where the surface rock is especially vulnerable to attack by surface water made acid by the soil zone. Such areas are called "karst", and often have other distinguishing features besides caves, such as sinkholes, springs, and exposed rock near the surface. Minerals that often form karst surfaces are limestone, gypsum, and salt. Scientists estimate that perhaps up to 1/5 of the Earth's land surface is made up of such karst areas. The second category, lava tubes, are formed when a specific type of volcano, called a "shield volcano", has been recently active. These tubes are generally shallow - only a few 10s of feet below the surface, and run down the slope of the volcano. They occur frequently in the areas of active volcanism, such as the Northwestern USA and the big island of Hawaii.

Home Page Haunted Cave ... Field Events THE ORIGIN AND GEOLOGY OF CAVES Woodward Cave is a solutional cave, formed by the removal of bedrock by circulating groundwater and by underground streams. The water transports the bulk of the material out of the cave in solution (i.e., - dissolved). Most solution caves are in limestone. Karst Topography Areas with abundant limestone caverns have karst topography. The term karst describes a landscape of characteristic landforms and subsurface features produced primarily as a result of solution of the underlying bedrock. The solution process is accompanied by other processes, particularly slumping of soil and bedrock materials, transport of insoluble debris through subterranean routes, and some mechanical wasting of slopes. The most characteristic landform is the sinkhole or doline.

Solution caves, however, have always been a source of wonder to man. How do these extensive, complex, and in some places beautifully decorated passageways develop? Solution caves are formed in limestone and similar rocks by the action of water; they can be thought of as part of a huge subterranean plumbing system. After a rain, water seeps into the cracks and pores of the soil and rocks and percolates deep into the ground. Eventually some of the water reaches a zone where all the cracks and pores in the rock are already filled with water. The term water table refers to the upper surface of this saturation zone.

STRUCTURAL, PETROGRAPHIC AND RELATIVE SOLUBILITY RELATIONSHIPS IN THE SINNETT-THORN MOUNTAIN CAVE SYSTEM, WEST VIRGINIA STOKOWSKI, S.J., Jr., 10 Clark Street, Suite A, Ashland, Massachusetts, United States of America, 01721 Sinnett-Thorn Mountain Cave System has passages in the limestones of the lower Helderberg Group and is on the eastern limb of a south-southwest plunging anticline. A petrographic examination of the limestone members exposed was undertaken; generally all are sparry allochemical carbonates with a ferroan calcite pore-filling cement that dissolves preferentially over adjacent calcite fossils. The major cave former, the New Creek biosparudite, has the least insoluble material and the coarsest pore-filling ferroan spar. In contrast to the active role in groundwater movement played by the solutional passages and fracture permeability mentioned above, there are passively formed "wells" connecting different levels of the cave. These wells follow steeply dipping fracture zones that are interpreted as compressive shear fractures related to local folding stresses. The wells have, at least initially, not channelized groundwater flow. Only one other major passively formed solution void has been found. It is in the "Big Room", where the New Creek limestone has been stratigraphically repeated by reverse faulting, and was developed subsequent to the major passage. from: Stokowski, S.

Home Tour information Buy Tickets On-Line About the cave ... Gift shop Pa Birthday Party Packages Press Receive information Geology of the Cave During this Ordovician Period, warm shallow seas covered the continent where we find Wisconsin today. Abundant shell life could thrive in these seas. Layers and layers of calcium carbonate shell debris accumulated and slowly hardened into limestone. Thousands of feet of limestone and other sedimentary rocks were laid down during this Ordovician Period. Millions of years ago, the seas receded leaving these layers of rock behind. Erosion began to wear them down. Today the exposed rock in Blue Mounds is a limestone called Galena dolomite, which is a specific kind of limestone containing some magnesium. Cave of the Mounds itself began to form about a million to a million and a half years ago when the Galena dolomite was still beneath the water table. The water table is defined as that level below

12. Cave Utah Geology UTAH cave geology. Many of Utah s caves began their lives over 300 million years ago as coral reefs at the bottom of a warm shallow ocean. http://www.caveutah.com/Geology.htm

UTAH CAVE GEOLOGY Many of Utah's caves began their lives over 300 million years ago as coral reefs at the bottom of a warm shallow ocean. As the planet buckled under the pressure of plate tectonics, the coral that had piled up on the bottom of the ocean over many millions of years, was compressed and uplifted into the limestone mountains and valleys scattered throughout the state of Utah. Today there is evidence of this reef in the limestone mountains. Small Crinoids, Horn Coral, Bryozoans, and other corals can be found protruding from limestone bands. As the limestone was pushed up and formed mountains, the rock cracked allowing water to seep into it, which led to the formation of Utah's spectacular caves. As rain water passes through the atmosphere it picks up small amounts of carbon dioxide turning the water into a weak carbonic acid. When this water passes through vegetation on the surface it absorbs even greater amounts of carbon dioxide and increases the acidity of the water. This is a weak acid to humans but over thousands of years it dissolves the limestone creating voids in the rock below. As long as water and carbon dioxide fill these chambers the rock continues to dissolve. However, the process begins to change once oxygen enters these passages. The oxygen allows the carbon dioxide to escape from the water as it enters the cave. With less carbon dioxide the droplet can no longer retain the minerals (calcium carbonate) it dissolved on it's way through the rock. These minerals are deposited on the walls, floors, and ceilings of the cave creating the beautiful formations typical of many caves. See Illustration.

13. Crescent Cave Geology Local geology. This section is based upon the survey of Crescent Cave, the British Geological Survey map of the area, Coal Board borehole data and W. http://www.cavinguk.co.uk/info/CrescentGeology.htm

Crescent Cave geology Navigation Back to the caving homepage Local geology This text has been reviewed by Andrew Farrant. The first 12 m depth of Crescent cave are in millstone grit and the remaining 69 m are in limestone. Therefore the cave has probably reached its limit of depth in the local area, although this seems certain to change should a major horizontal system be encountered. See paragraph on possibility of passing the shale band below. The altitude of the resurgence of Crescent cave is 355 m (Ffynnon Sion Sheffrey - dye trace 48 hrs). This is about 185 m below the entrance to Crescent Cave giving a maximum depth for the cave of 185 m plus whatever may be below the water table. From the appearance of the end of the streamway in Crescent Cave, it seems that any extension will remain small until the major system is encountered. Any major system encountered is likely to be gently dipping and will probably be running at the bottom of the Dowlais Limestone. Inlets are likely to be of a similar nature to Crescent Cave, being steeply dipping and due to extensive faulting, very much linear. It is also possible that many fossil passages exist from older, perhaps glacial, systems. Hydrology within the cave All of this section is based on speculation from the locations of passages and sinks with respect to each other, and not from dye tracing (except the trace to the rising).

Home About ELC Site Map Contact Us ... Food Caves Some of the most interesting landscapes in the world are hidden beneath our feet. One fifth of the landscape in the U.S. are karst ecosystems, which include caves, sinkholes, and underground streams formed by the slow dissolving of bedrock. Karst areas occur in twenty states, although smaller karst regions appear throughout the U.S. Caves and karst regions are found throughout the world. Karsts are formed when acidic groundwater moves through fractures and small openings in the rock to create larger passages. All rainwater is slightly acidic, because moisture in the air reacts with carbon dioxide to form carbonic acid. Most karst regions form at or just below the water table. Caves have been used as a source of water, for storage, and for mining. In the U.S. 250 caves were mined during the Revolutionary War, the War of 1812, and the Civil War for saltpeter, which was used to make gunpowder. Bat guano from caves was used as fertilizer until the early 20th century. Caves are mined for their limestone, marble, and dolomite.There are caves over the world, though some are more accessible than others. Check out this page to find out about caves you can visit.

Rates Blanchard Springs Caverns Cave Geology Millions more years passed, and the widening river eroded to a new level, deeper and deeper into the limestone. The surface of the land began to show signs of sinkholes, where rain water drained directly into the limestone below. The cavities formed beneath the surface in the saturated limestone joined into one continuous channel as the underground river moved sideways between the layers of rock. The water continued to seep and move through the rock, dissolving and enlarging the soon-to-be caverns. Still thousands, maybe even millions, of years later, the eroding river dropped to a new, lower level. The water drained from the underground river, leaving the cave high and dry. While another system of caves was forming at a new water level below, dripping water entering the dry rooms and passages started depositing calcium carbonate and other minerals in the form of stalactites, stalagmites, and numerous other dripstone features. The speleothems grow as long as groundwater enters the cave.

Of Caves and Speleothems This is a story told by Jerry Vineyard, former Missouri deputy state geologist and one of the founders of the MSS. The tale goes that a young boy wrote Vineyard, and asked him to send him "all the rocks in Missouri." Vineyard wrote back, and explained to the zealous youth that if he sent him all the rocks in Missouri, there would be no more Missouri, and he was very sorry, but could not fulfill his request. It is just as impossible in a few words to describe the cave geology of Missouri, since, by definition, a cave is that part of the geology which "isn't there". The processes by which caves are formed are fairly, but not entirely understood, as are the processes by which speleothems , commonly called cave deposits, are formed.
