Insects Home Eastern Wildflowers General Topics Natural History Ecology Family Environment Evolution Home Education Home Conservation Geophysics Paleontology Commercial Organizations Return to Geology Main Page Photo courtesy of John Betts Fine Minerals Books About R ocks and Minerals I have always been slightly crazy about rocks and minerals. As a child my mother indulged me even though the suitcases on vacations always came back packed with rocks rather than clothes. Trying to collect rocks growing up in eastern North Dakota was an exercise in futility, however, and insects came to occupy me later in my professional life. However I still find myself poking around among the rocks and stones whenever I have the chance, and fossils and rocks seem to occupy every empty shelf in the house. This page is an introduction to the minerals section and contains links to web sites containing general information about mineralogy.

18. The Minerals Of Igneous Rocks Piece of cake you say, I saw most of these minerals when I did the minerals Exercise Biotite is differentiated from amphibole by shape of the crystals http://geology.csupomona.edu/alert/igneous/igmin.htm

MINERALS OF IGNEOUS ROCKS To correctly classify many igneous rocks it is first necessary to identify the constituent minerals that make up the rock. Piece of cake you say, I saw most of these minerals when I did the Minerals Exercise or I have them in my mineral collection. Well, its not quite that easy. The mineral grains in rocks often look a bit different than the larger mineral specimens you see in lab or museum collections. The following section is meant to assist you in recognizing common rock-forming minerals in igneous rocks. Refer back to it often as you attempt to classify your rock specimens. Plagioclase Plagioclase: the white or chalky looking grain is the common feldspar, plagioclase. Plagioclase is the most common mineral in igneous rocks. The illustration to the left shows a large chalky white grain of plagioclase. The chalky appearance is a result of weathering of plagioclase to clay and this can often be used to aid in identification. Most plagioclase appears frosty white to gray-white in igneous rocks, but in gabbro it can be dark gray to blue-gray. If you examine plagioclase with a hand lens or binocular microscope you can often see the stair-step like cleavage and possibly striations (parallel grooves) on some cleavage faces. Some potassium feldspar is white like plagioclase, but is usually a safe bet to identify any frosty white grains in igneous rocks as plagioclase. Expect to find plagioclase in most phaneritic igneous rocks and often as phenocryts in aphanitic rocks.

Overview Guide to Reading Key Terms Self-Test ... Glossary Crystals formed by precipitation from a solution may grow inward from the walls of a container. Geodes are a spectacular example of this phenomenon. Credit Stephen Marshak Guide to Reading Most of Chapter 3 is devoted to the scientific approach to mineral study, but woven throughout the chapter are consumer-type topics such as the questionable magical powers of crystals and the beauty and legends of gemstones (diamonds and more). Mineral identification is the next topic. How do you tell one kind from another when there are so many? Fortunately there are few enough common ones that examination of a few physical properties generally allows identification of specimens in either the field or the lab.
