Classification of Geological Rocks

Geological rocks can be classified based on various criteria, including their formation process, mineral composition, and texture. Here is a brief overview of the classification of geological rocks:

1. Igneous Rocks: Igneous rocks are formed from the solidification of molten material, such as magma or lava. They can be further classified into two types:

- Intrusive Igneous Rocks: These rocks form when magma cools and solidifies beneath the Earth's surface. Examples include granite and diorite. - Extrusive Igneous Rocks: These rocks form when lava cools and solidifies on the Earth's surface. Examples include basalt and obsidian.

2. Sedimentary Rocks: Sedimentary rocks are formed from the accumulation and lithification of sediments. They can be further classified into three types:

- Clastic Sedimentary Rocks: These rocks are formed from the accumulation of fragments of pre-existing rocks. Examples include sandstone and shale. - Chemical Sedimentary Rocks: These rocks are formed from the precipitation of minerals from water. Examples include limestone and rock salt. - Organic Sedimentary Rocks: These rocks are formed from the accumulation of organic remains, such as shells or plant material. Examples include coal and chalk.

3. Metamorphic Rocks: Metamorphic rocks are formed from the transformation of pre-existing rocks due to high temperature and pressure. They can be further classified into two types:

- Foliated Metamorphic Rocks: These rocks have a banded or layered appearance due to the alignment of minerals. Examples include slate and gneiss. - Non-foliated Metamorphic Rocks: These rocks do not have a banded or layered appearance. Examples include marble and quartzite.

It is important to note that this is just a general overview of the classification of geological rocks. There are many more specific rock types within each category.
