Definitions:

Siltstones

Fine-grained sedimentary rocks that consist predominantly of silt particles, smaller than sand grains but larger than clay, often formed in quiet water environments.

Lime Muds

Fine-grained sediments composed largely of calcium carbonate, typically formed in marine environments where organisms such as coral or foraminifera are prevalent.

Carbonate Rocks

Sedimentary rocks, such as limestone, that are primarily composed of carbonate minerals, typically formed in marine environments.

Oxidation

Oxidation is a chemical reaction in which a substance loses electrons, often resulting in rust in metals or changes in rock minerals due to exposure to oxygen and water.
