The Natural Resources Conservation Service (NRCS) installs, operates and maintains an extensive, automated system to collect snowpack and related climatic data in the western United States called SNOTEL (for SNOwpack TELemetry). SNOTEL sensors collect hourly data on temperature, precipitation and snow water equivalent. Data can be displayed as tables or graphs for individual stations, drainage basins ... Full description.

This site examines the crystal chemistry of some common mineral groups, including garnet, plagioclase, pyroxene, mica (muscovite and biotite), and amphibole. For each group, the topics considered include: the sites in the crystal structure on which the principal substitutions take place, the typical ranges of observed composition variation, how to assess the quality of analyses from looking at the ...

This site is a lecture by Dr. Stephen Nelson from Tulane University that explores the 32 possible combinations of symmetry operations that define the external symmetry of crystals. The lecture defines the six crystal systems (triclinic, monoclinic, orthorhombic, tetragonal, hexagonal, and isometric) and explains the derivation of the Hermann-Mauguin symbols (also called the international symbols) ...

This site provides the syllabus for Dr. Barb Dutrow's class, taught at Louisiana State University, entitled Earth Materials and the Environment. The course examines minerals and mineral dusts as both problems and solutions to environmental issues, as well as public policy. The syllabus includes direct links to required readings in the current literature, in-class overheads, and practice exams. The ... Full description.
