Intergrowth texture forms when two minerals crystallize together or through exsolution in igneous rocks. Common types include graphic, myrmekite, exsolution, cavity, radiate, reaction, and pegmatite textures, each revealing mineral interactions and cooling history....

The textures of igneous rock define their crystallinity, grain size, and crystal relations, reflecting their cooling history and formation conditions. Various types of textures of igneous rock: (A) Crystallinity: Defines the degree of crystallization. Holocrystalline:...

Deposition definition refers to the process where transported sediments settle due to changes in fluid flow. Hjulstorm’s diagram illustrates its control by velocity and turbulence. Coarser particles settle near the source, while finer ones travel farther,...

Types of Metamorphic Texture form due to varying pressure and temperature conditions. They are classified into foliated (slaty, schistose, phyllitic, gneissic) and non-foliated (granulose, mylonitic, hornfelsic) textures. Other textures like augen, porphyroblastic,...

Metamorphic Reaction: The study of metamorphic reactions provides vital information about the pressure and temperature conditions of metamorphism. During metamorphism, chemical reactions between components take place to produce a new mineral assemblage. The agents of...
