Geological Survey. Federal government mineral exploration-assistance program files. Scanned documents describing applications for Federal assistance in exploring for certain strategic and critical minerals, including where the deposits were examined what minerals were found, and whether mining had occurred.
These files span the years to Coal mines and other energy resources. We have no comprehensive database of coal mines, but can provide links to some online resources. Geologic data. Geologic map data. Geologic maps of US states. Digital geologic maps of the US states with consistent lithology, age, GIS database structure, and format.
Geologic map of Alaska. Digital compilation and reinterpretation of published and unpublished geologic mapping of Alaska. Basement domains of the conterminous US and Alaska. Seventy-seven major components of the North American continent were delineated at a general scale ,, ; including the general composition, geological environment, and types of primary metals endowments that can be expected in each domain.
Geology of the conterminous United States. A digital version of the King and Beikman Geologic Map of the United States, originally published at a scale of ,, It excludes Alaska and Hawaii. Geology of Puerto Rico. Large-area material map of the conterminous US. Maps of exposed surface mineral groups derived from automated spectral analysis of satellite and airborne imaging systems; these data suggest areas that may contain mineral deposits of various types. Maps of hydrothermal alteration in the Basin and Range province of the US.
Maps and data showing the geographic distribution of surficial minerals likely produced by hydrothermal alteration, which may indicate areas permissive of gold and copper mineral deposits. National geochemical database. National Geochemical Database: Rock. Geochemical analysis of rock samples collected and analyzed by the USGS. National Geochemical Database: Sediment.
Geochemistry of sediments from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are of stream sediment in the continental US and Alaska. National Geochemical Database: Soil. Geochemistry of soils from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are from the continental US and Alaska.
National Geochemical Database: Concentrate. Geochemistry of concentrates from the National Geochemical Database. Recent, focused geochemical surveys. Alaska Geochemical Database. Geochemical analysis of rock, sediment, soil, mineral, and heavy mineral concentrate samples in Alaska analyzed from through Geochemical and mineralogical data from soils in the conterminous United States. No internet connection is required.
Ideal for field use. Entries for more than common mineral species cover the vast majority of occurrences without presenting an overwhelming number of obscure species rarely encountered. The software provides hand sample photos, photomicrographs of thin sections, physical properties, crystal structure animations, optical properties, classification, and occurrence data as well as partial data for many more species, varieties, groups, sub-groups, and series.
Search for color, hardness, and streak in field and classroom uses. Use the app as a companion to a polarizing light microscope by searching for birefringence or refractive index. Identify your unknown mineral through use of any or all 54 search criteria. The comprehensive search feature allows mineral identification by using known physical properties such as color, streak, luster etc.
Or, you can visually search the hand sample photos and photomicrographs using the pop-up image galleries. I love the 3D structure renderings that can rotated. But the interface is modal, so you must back out of a listing just to see the photos! There should be but a single screen for each mineral that I can just scroll. I would also appreciate a wiggle mode for the 3D structures. GameStop PS5 in-store restock. Baby Shark reaches 10 billion YouTube views.
Microsoft is done with Xbox One. Windows Windows. Most Popular. New Releases. Desktop Enhancements. Networking Software. Trending from CNET. Mineral identification is finally made easy with the Mineral Database compiled by M.
Darby Dyar and Mickey E. Gunter and illustrated by Dennis Tasa. This app provides a quick reference for students, educators, professionals, or anyone interested in minerals. This searchable database is easy to use. No internet connection is required. Selected mineral definitions spanning the last century defining the mineral kingdom as matter other than that of the plant or animal kingdom.
Crystallography This section contains tutorials on the 36 crystal classes. Along with this information are links to tables of each class with all the minerals in that class. Printer-ready PDF files of paper crystal models assembly required of the crystal classes can be found here. The rotating form on your left is an actual java applet and not an animated GIF image. The jmol version is located here.
