University of Minnesota''s Mineral Pages: Calcite

If a mafic magma cools slowly enough, dense magnetite crystals may settle as they crystallize, to form large magnetite ore bodies with a strong magnetic character. Magnetite can also form during contact metamorphism of impure ironrich limestone, and in high temperature hydrothermal sulfide vein deposits.

electrical conductivity of sandstone, limestone and

Summary. The electrical conductivity of cylindrical cores of Westerly granite, Indiana limestone and Nugget, St Peter and Kayenta sandstones was measured at about 25°C in vacuo, in air, and after saturation in distilled water, tap water, and 0.1 MNaCl solution.The threeelectrode technique with a guard ring and the twoelectrode technique without a guard ring were used.

Magnetic properties. The magnetic properties of rocks arise from the magnetic properties of the constituent mineral grains and crystals. Typically, only a small fraction of the rock consists of magnetic minerals. It is this small portion of grains that determines the magnetic properties and magnetization of the rock as a whole, with two results: (1) the magnetic properties of a given rock may
