Petrology is important because it can inform mineral prospecting studies. Petrology is the branch of geology that is concerned with the study of how rocks are formed and how they change over time. This knowledge can help a geologist know ...

Granite is a common, coarse-grained, hard igneous rock consisting chiefly of quartz, orthoclase or microcline, and mica. Granite has been used as a building material since ancient times. It is one of the oldest and most durable building products available, ...
What is difference between basalt and granite?
How are extrusive and intrusive rocks formed? How igneous rocks formed?
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary Rocks Sedimentary rocks are formed from pieces of ...
The mining industry routinely collects samples to assist with decision making, whether for exploration, resource estimation, grade control, or plant design and balances. Poorly designed sampling protocols can result in elevated project risk by increasing variability. Critically, such variability produces ...
The process in which a portion (sample of ore) is selected in such a way, that its composition will represent the average composition of the entire bulk of ore. Such a selected portion is a sample, and the art of ...
The geological time scale is based on the the geological rock record, which includes erosion, mountain building and other geological events. Over hundreds to thousands of millions of years, continents, oceans and mountain ranges have moved ...
The transformation of limestone into marble usually occurs at convergent plate boundaries where large areas of Earth’s crust are exposed to the heat and pressure of regional metamorphism. Some marble also forms by contact metamorphism when a hot magma body heats adjacent ...
