Rock Types

If the green mineral is chlorite the rock should be named chlorite schist ^ Greisen is a pneumatolytically altered granitic rock Greisen contains lots of quartz and mica plus several exotic minerals like cassiterite tourmaline topaz etc Greised is a metamorphic rock that metamorphosed itself — hot fluids that altered the rock were provided by the cooling magma body itself ^

Rock Types Their Resistance to Weathering

In a region containing multiple kinds of rock their relative weathering resistance or lack thereof helps shape the lay of the land Roughly speaking rock layers standing high on the countryside are more resistant to weathering as well as erosion – the two forces go hand-in-hand – than those underlying valleys and other lowlands

The Quartz Page Quartz as a Rock

- The lack of quartz in an igneous rock might be solely attributed to the bulk chemical composition of the magma it formed from if the concentration of SiO 2 is too low it does not allow for quartz to form as a mineral simply because there is no silica left over from the mineral forming processes

Mineral oil

Mineral oil is used in a variety of industrial/mechanical capacities as a non-conductive coolant or thermal fluid in electric components as it does not conduct electricity and functions to displace air and water Some examples are in transformers where it is known as transformer oil and in high-voltage switchgear where mineral oil is used as an insulator and as a coolant to disperse

Mineral

Minerals are not equivalent to rocks A rock is an aggregate of one or more minerals or mineraloids Some rocks such as limestone or quartzite are composed primarily of one mineral – calcite or aragonite in the case of limestone and quartz in the latter case Other rocks can be defined by relative abundances of key (essential) minerals a granite is defined by proportions of quartz
