  • The Acid Test for Carbonate Minerals and Carbonate Rocks

    The Acid Test on Rocks. LIMESTONE, DOLOSTONE, AND MARBLE. Some rocks contain carbonate minerals, and the acid test can be used to help identify them. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Dolostone is a rock composed of almost entirely of dolomite. It will produce a very weak fizz when a drop of cold hydrochloric

  • Metamorphic Rocks Lesson #14

    Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. Igneous rocks form when rocks are heated to the melting point which forms magma. Sedimentary rocks are formed from the cementing together of sediments, or from the compaction (squeezing together) of sediments, or from the recrystallization of new mineral grains which are larger than the original crystals.

  • Soil Unit Weight on the Geotechnical Information Website

    Unit weight of a soil mass is the ratio of the total weight of soil to the total volume of soil. Unit Weight, g, is usually determined in the laboratory by measuring the weight and volume of a relatively undisturbed soil sample obtained from a brass ring.Measuring unit weight of soil in the field may consist of a sand cone test, rubber balloon or nuclear densiometer.

    Most rock and soil contains numerous open spaces where water may be stored and through which water can move. Permeability, or hydraulic conductivity, is a measure of the ease of movement of fluid and gas through the open spaces and fractures. The properties of soil and rock have significant impact on water movement through the interstitial spaces.
