Geological Classification of Rocks

On the basis of geological occurrence, rocks are classified into three categories: Sedimentary Rocks Igneous Rocks Metamorphic Rocks Sedimentary Rocks Rocks formed due to deposition of minerals one over another due to action of water, wind, and other natural agents is called sedimentary rocks. Sandstone Limestone Shale Claystone Conglomerate Dolomite Igneous Rocks Rocks formed due to volcanic action when magma or lava cools down and solidifies is called igneous rocks There are two types of igneous rocks: Plutonic Rocks Igneous

Types of Geological Formation

There are four types of geological formation: Aquiduct Aquitard Aquiclude Aquifuge Aquiduct Aquiduct are geological formation which contains water and can yield water. They are porous as well as pervious. They are water bearing strata from from underground water is generally extracted. Aquitard Aquitard are geological formation which contains water but yield is very less as compared to aquiduct. They are porous strata but less pervious than aquiduct. Aquiclude The geological formation which contains water but doesn’t allow extraction of
