What is the difference between mineralogy and petrology?
Petrology is the study of rocks – igneous, metamorphic, and sedimentary – and the processes that form and transform them. Mineralogy is the study of the chemistry, crystal structure and physical properties of the mineral constituents of rocks.
What is the hardest type of rock?
Since all minerals are also rocks, diamond is the hardest rock. Rocks that contain more than one mineral can’t really have a single ‘hardness’ rating because each of the minerals they are comprised of will have a different hardness. For example, most granite is made up of quartz, feldspar, and mica.
What is the difference between mineralogy and geology?
Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.
What is the difference between petrology and petrography?
Experimental petrology involves the laboratory synthesis of rocks for the purpose of ascertaining the physical and chemical conditions under which rock formation occurs. Petrography is primarily concerned with the systematic classification and precise description of rocks.
Why do we study mineralogy?
Rocks and minerals are important for learning about earth materials, structure, and systems. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math.
Why is petrography useful?
Archaeologists use petrography to identify mineral components in pottery. This information ties the artifacts to geological areas where the raw materials for the pottery were obtained. In addition to clay, potters often used rock fragments, usually called “temper” or “aplastics”, to modify the clay’s properties.
Why is it important to study mineralogy?
Mineralogy is an important discipline for several reasons. For one, the study of the composition of the earth’s crust gives scientists an idea of how Earth was formed. The discovery of new minerals could provide useful materials for industry.
