Hydrothermal transformations and weathering are important mineralizing processes in carbonatite-related ores. But the transformation products of mafic minerals, such as the clay minerals, vermiculite and interstratified phases, preclude the use of X-ray diffraction, particularly the Rietveld method, for mineral phase quantification.

4.4 Electrical conductivity of minerals and rocks

A subset of minerals, principally metallic sulfides (ore minerals), are electronic semiconductors. A form of carbon, graphite, is a metallic conductor which is found in many crustal rocks. Figure 4.4.1 shows the range of conductivities encountered in crustal minerals and rocks.

Ore | RuneScape Wiki | FANDOM powered by Wikia

An ore is an item (usually a type of unrefined metal) that can be mined from rocks or mineral veins using the Mining skill and a Pickaxe. Items such as gems, clay, granite, and essences are not ores per se, however they are still discussed on this page as they can be obtained via Mining. Metal ores can be smelt into bars using the Smithing skill.

Clay minerals - Wikipedia

Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them.
