Amber:Arboreal Gold from "Amber: Window to the Past", Abrams/AMNH (NY), courtesy of Dr. David Grimaldi. Welcome to “ Amber: Arboreal Gold ”. As you can see, I really ‘dig’ amber. November of 1998, I was able to travel to Cape Breton Island, Nova Scotia, where I retrieved a fine collection of Baltic amber and brought it home. My partner Paul Howell and I have established a website, the Amber Gallery . On this new site, you may view or purchase Baltic amber specimens. My own web page features Dr. George Poinar of Oregon State University, and his wife and research partner Roberta. He has given me permission to publish photographs and excerpts of his book “ The Quest for Life in Amber ”, a follow-up to his book “ Life in Amber ”. Dr. Poinar released his new book, The Amber Forest in July of 1999. This book covers the origins of Dominican amber. Most recently in 2002, he has published his work with Lebanese amber. These books are available on Amazon and Barnes and Noble's site, and probably in your local university library in the geology and entomology departments. Dr. David Grimaldi of the American Museum of Natural History in New York City also granted me permission to showcase his book “ Amber: A Window to the Past .” Grimaldi has a new publication due out in October of 2000. Both are exceptional scientists and sometimes disagree on research technique and method. I have a great deal of respect and admiration for them both. So what is good science without a little controversy? I enjoy reading and following their work and hope you will, too.

The Geology of Placer Deposits If you are interested in finding gold it is important to first learn about placer deposits. A good amount of the information that we know now has been given to us by the early miners and prospectors went through absolutely everything you can imagine digging through and searching every possible place they could to find gold. Geologists have said that they do not know which is the best method at finding everything there is to know about the gravel deposits that are still in the earth and pretty much all we can do is continue doing what the early miners did. The history and structure of geological structures are very complex and even the best engineers are stunned by some of them. There are fragmentary benches and places with rich gravel deposits that are still totally hidden from the top and even from the passages underground that enter into the lower main channels that are very tempting for those interested in getting gold too. It has been said that there is still a great amount of gold to be found the thing is finding it. Something important to keep in mind is that almost all the areas you go to have probably at some point or time been prospected on. Make sure to not waste time in areas that you know have not been productive before. Look through areas where you know there is gold and use the knowledge you have learned from those that were there before you.

EXPLORE THE GEOLOGICAL WONDERS OF SOUTH AFRICA... VISIT THE GEOLOGY OF THE WITWATERSRAND TOUR 2 DESCRIPTION Back to Tours main page The geology and gold mines of the Witwatersrand are world-famous. Nearly half of all gold ever mined has come from the extensive Witwatersrand conglomerate reefs that were first found near Johannesburg in 1886, not far from the city centre. Our tour focuses on the important and exposed geological formations that make up the Witwatersrand stratigraphy in and around Johannesburg. The tour includes numerous short geological stops in the suburbs, as follows: We see several outcrops of intrusive granodiorite and tonalite, and even earlier metamorphosed greenstone remnants of serpentinite and amphibolite, all forming part of the ancient Johannesburg Granite Dome on which the Witwatersrand formations were deposited. The top of Northcliff Hill in the north-western suburbs of Johannesburg provides a panoramic view of the city and a regional geological overview. We see the main formations making up Johannesburg's prominent ridges. Later we make stops at some key horizons of the West Rand Group, such as the Orange Grove Quartzite, the well-known Contorted Bed, and the Brixton Quartzite.

THE FORMATION OF GOLD: Formation Gold is formed in a wide variety of hydrothermal deposits, which may then be eroded and the gold re-deposited as sedimentary placer deposits. In hydrothermal deposits, gold is most commonly associated with silver and the base metals, copper, lead and zinc. Most of these deposits are quartz veins deposited from hydrothermal fluids in fault zones at medium (mesothermal) or shallow (epithermal) depths in the crust. Gold deposit within quartz rock GEOLOGY OF THE THAMES GOLD FIELD: Epithermal quartz lodes in Cenozoic volcanic rocks Epithermal gold-silver deposits in Northland and in the Hauraki Goldfield were formed in past geothermal systems associated with volcanism that was active in the Miocene­Pliocene, whereas gold is being deposited today in active geothermal systems in the Rotorua-Taupo area, in association with Quaternary volcanism. The Hauraki Goldfield contains about 50 known epithermal gold-silver deposits that were deposited by geothermal systems associated with volcanism that was active during the Miocene and Pliocene. About 1360 t of gold-silver bullion were produced between the 1860s and 1952 (about 34% of New Zealand's total gold production), mostly from deposits hosted by andesite and dacite.

Ministry of Lands and Mineral Resources Fiji Mineral Resources Department FIJI'S GEOLOGY Regional Setting Fiji lies at the midpoint of the opposing Tonga­Kermadec and New Hebrides convergence zones, separated from these actual convergence zones by two extensional back­arc basins, the North Fiji Basin to the west and the Lau Basin to the east, and a series of transform faults including the Fiji Fracture Zone and the Matthew­Hunter Ridge. Most reconstructions of the past configuration of this part of the Pacific indicate, however, that Fiji was not so long ago an integral part of the Pacific " Rim of Fire ", the complex plate boundary between the Pacific and the Indo­Australia Plates. This boundary is well recognised as the locus of several major world-class porphyry copper­gold and epithermal gold systems. View Regional Setting Geological Map - SW Pacific (45Kb) or the smaller .gif version of it. Before the Late Miocene, roughly 8 million years (Ma) ago, the Pacific crust was subducted from the east along this plate boundary, with Fiji forming part of an extended Outer Melanesian island arc system, the Vityaz arc, that incorporated the Solomon Islands, New Hebrides, Fiji and Tonga island arcs. Remnants of this subduction zone are preserved as part of the Vityaz Trench, whilst Eocene­Miocene cores of the ancient arc system form part of the geological basement in Tonga ('Eua), Fiji (Viti Levu) and Vanuatu.

GEOLOGY OF THE JINFENG GOLD DEPOSIT - A CHINESE ‘CARLIN’ ANALOGY - Greg Jones Asset Manager and Chief Geologist Sino Gold Limited, Level 8, 17 Bridge Street, Sydney, NSW 2000 Key Words : gold, Carlin type, geology and geochemistry, resource estimate, China. ABSTRACT Located within the Golden Triangle region in southern China, Jinfeng is believed to be China’s largest undeveloped gold deposit. Sino Gold Limited has commenced bankable mine feasibility study on the deposit and is hoping to develop a 200,000oz/a operation. Drilling and underground development has successfully defined robust mineralization to a depth of over 500m below the surface and outlined a resource of 2.6Moz. Mineralization is hosted within Triassic marine turbidites, including calcareous clastics, deposited on the southern margin of the Yangtze craton. The bulk of mineralization is primarily hosted by the composite F3 fault, a west-north-west striking, reverse structure cutting the turbidites at a high angle. Recent drilling has also intersected significant stratabound mineralization hosted by calcareous arenites within the footwall of the F3. Sino Gold’s work has confirmed the continuity of mineralization and clearly indicated that the deposit exhibits many of the features that characterise the Carlin deposits of Nevada, USA including gold morphology (submicron within arsenical pyrite and pyrite), geochemical signature (elevated As, Hg, Sb, and Tl), alteration and general host lithologies (fine grained clastics, often calcareous). The overall depositional environment (depth of formation and temperature) and probable fluid chemistry (eg. pH, NaCl%) also mimics that generally accepted for these deposits and it is considered that the Jinfeng deposit represents a true “Carlin” analogy.

Geology of the Great Falls-Bethesda area, Maryland by Bob Kopp 4 March 02001 Physical Setting The State of Maryland is located on the Mid-Atlantic seaboard of the Eastern United States. It is bordered by Pennsylvania to the north, West Virginia and Virginia to the south and west, and Delaware to the east. It is home to much of the Chesapeake Bay. Most of its southern border is defined by the Potomac River, whose northern and southern branches join together in the northwest of the state, at Cumberland. Figure 1: The physiogeographic provinces of Maryland, with the Falls Church quadrangle indicated. Maryland encompasses five physiogeographic provinces: the Appalachian Plateaus Province, the Ridge and Valley Province, the Blue Ridge Province, the Piedmont Plateau Province and the Coastal Plain Province. The Appalachian Plateaus Province, the Ridge and Valley Province and the Blue Ridge Province consist mainly of folded and faulted sedimentary rocks. The Appalachian Plateaus Province is largely composed of shale, siltstone and sandstone, with exposed Devonian rocks. The Ridge and Valley Province consists of two sections, the Folded Appalachian Mountains Section in the west and the Great Valley in the east. The western section is composed of middle Paleozoic shale and sandstone. The eastern section, home to the Hagerstown Valley, consists of early Paleozoic limestone and dolomite.

Host rocks consist of an intrusive subvolcanic gabbro sill and mafic and felsic volcanic rocks formed in a volcano-sedimentary environment* This sequence was intruded by felsic and diabase dykes. Mineralization consists of native gold and chalcopyrite in brecciated quartz veins, formed as fracture-fillings, located in three subparallel shear zones cutting the gabbro, mafic and felsic volcanic rocks. Chalcopyrite, pyrite, pyrrhotite and minor sphalerite are found in breccia interstices and in disseminations near the veins but are not spatially related to the gold mineralization. The gold is contained in quartz and albite. Textures show it was the last mineral to be deposited in the veins. A mineral identified as anhydrite is found in the 'main' shear and the mafic volcanic rock unit of the mine sequence. As anhydrite has not been found elsewhere in the region it may be possible to use its presence as a stratigraphie indicator.

Home About DES DES Programs Public Information ... Geology Environmental Fact Sheet Print Version CO-GEO-1 Gold in New Hampshire by Eugene L. Boudette, retired N.H. State Geologist To many, the mention of gold conjures up an image of a lonely old prospector toiling away in a far-off desert or in the high Sierra or Yukon Territory. But gold can be found a lot closer to home. Small amounts have been found in vein and placer deposits in New Hampshire. This document is intended to shed some light on this precious metal and its presence in the Granite State. The nature of gold Gold is a noble element in several ways. Its unique qualities have led to the creation of artifacts of aesthetic beauty and, indeed, empires across the planet. The rocks of New Hampshire Volcanic rocks, not abundant in the state, are only found associated with the granitic rocks of the southern White Mountains. About 50 percent of the state is underlain by metamorphic rocks which are in part derived from the recrystallization of rocks which were of volcanic origin. The remainder of the rocks of the state are granitic or related rocks ( see map Gold in the rocks and water Trace amounts of gold are found in nearly all of the rocks and surficial deposits of New Hampshire, and they can be identified dissolved in natural water (usually less than one part per billion). Gold in water, especially groundwater, is of scientific interest only. Mapping the distribution of gold in groundwater is a technique (geochemical exploration) that can be used to find gold lode deposits as well as other metals. Rocks enriched in dispersed gold in New Hampshire are of primary interest to mineral producing companies which have been exploring here. Modern gold exploration is centered more on low grade, large volume deposits than on high grade lode deposits such as quartz veins. Such quartz veins are, however, important sources for rock and mineral collections throughout the state.
