Metamorphic rocks are classified on the basis of foliation into the following types: 1. Foliated Metamorphic Rocks 2. Non-Foliated Metamorphic Rocks. 1. Foliated Metamorphic Rocks: i. Slate: Slates are formed due to dynamic regional metamorphism of shales and other argillaceous rocks. Slates are characterized by the ‘presence of numerous closely- spaced parallel planes of splitting […]

This article will help you to learn about the rock cycle with diagram. The change of one rock into another type under different conditions of heat, pressure, weathering and erosion is known as rock cycle. Initially, all minerals originated from igneous rocks. As soon as igneous rocks are exposed they are weathered and eroded by […]
