GEOLOGY

Detailed explanation-1: -Fluids flowing through the rock and organisms may precipitate new minerals in the pore spaces between grains to form a cement that holds the sediment together. Common cements include quartz, calcite, and hematite.

Detailed explanation-2: -Compaction and Cementation Dissolved minerals in the ground water precipitate (crystallize) from water in the pore spaces forming mineral crusts on the sedimentary grains, gradually cementing the sediments, thus forming a rock.

Detailed explanation-3: -is where new minerals stick the grains together – just as cement (from a bag) binds sand grains in a bricklayer’s mortar. If you look carefully at the microscope photo, you can see mineral crystals that have grown around the sediment grains and bonded them together.

Detailed explanation-4: -Thus, of the eight common igneous minerals, only quartz, K-feldspar, and muscovite are commonly seen in sedimentary rocks. These minerals are joined in sedimentary rocks by clay minerals, calcite, dolomite, gypsum, and halite. The clay minerals form during mineral weathering.

Detailed explanation-5: -The definition of cementation is a process where sediment is chemically glued together when minerals precipitate from the water they are dissolved in and fill the pore space between compressed sediment.
