The word mineral has many meanings, depending on what we are looking at. Minerals in the geological sense are substances or objects of chemical compounds original or composed of natural processes, have certain chemical and physical properties, and are usually solid in shape.
The use of physical properties to identify minerals will be necessary for the second lab exam, so you should become very familiar with using physical properties and the mineral identification charts to identify hand specimens of minerals. Other example questions that could appear on …
its physical properties. For example, the extreme hardness of diamond makes it a highly efficient abrasive, and the piezoelectric nature of quartz is the basis for its use in electronic equipments. Many of the physical properties of minerals that will be discussed in this lecture will simultaneously be correlated with the mineral's chemical ...
Pyrolusite mineral, essentially containing manganese dioxide is an important ore of manganese. It has a metallic luster, a black or bluish stream, and speedily tarnishes the fingers. The Pyrolusite is named from the Greek pyro and louein meaning " fire" and " to wash" because it was used to remove tints from glass.
