Minerals, Rocks & Rock Forming Processes

Rock bodies that cool beneath the surface are generally described as Plutons.A batholith is a large former magma chamber, often many miles across. A sill is a sheetlike injection of magma between layers of sedimentary rock. A dike is a sheetlike body that fills a fracture that cuts across other rocks. A laccolith is a small magma chamber at shallow depth (roughly lens shaped).

Sedimentary Rocks: Meaning, Composition and Weathering

7. Lithification and Diagenesis of Sedimentary Rocks: Lithification means the formation of the sedimentary rock which involves the compaction of sediment by burial and subsequent expulsion of water or air from the spaces between the grains. In the process of compaction the porosity is very much reduced and the volume of the sediment decreases.
