Here is a list of seven important metamorphic rocks: 1. Slate 2. Schist 3. Gneiss 4. Quartzite 5. Marble 6. Phyllite 7. Hornfels. 1. Slate: Slate is an extremely fine-grained metamorphic rock characterized by a slaty cleavage by virtue of which it can be readily split into thin sheets having parallel smooth surfaces. The slaty cleavage is due to parallel [...]
Metamorphic processes cannot be either observed directly or demonstrated practically. They are very gradual, large-scale processes involving geological times measurable in terms of millions of years. It is only through the study of their effects on the rocks that conclusions can be drawn regarding the nature of the process through which those rocks have passed. Different rocks behave differently under [...]
In this article we will discuss about:- 1. Introduction to Ore Deposits 2. Origin of Ore Deposits 3. Types. Introduction to Ore Deposits: Minerals form chief source of all the industrial metals and non-metals. The commonly used metals like aluminum, copper, iron, lead, zinc etc. are all manufactured using minerals as raw materials. Similarly non-metals like glass and refractories are [...]
