what is marine deposits
Answers
Answer
Marine Deposits
bottom sediments of modern and ancient seas. They are more common than continental deposits, constituting more than 75 percent of the volume of the sedimentary shell of the earth’s continental crust. Marine deposits first formed when seas appeared in the Archean or even farther back in the geological past, about 3.5–4 billion years ago, and have continued to form throughout geological history. As a result of diagenesis, fossil marine deposits have been transformed into sedimentary rock. Marine deposits include most of the lime-stones, dolomites, marls, and siliceous rocks, a significant part of the clays and argillites, siltstones, sandstones, and conglomerates, and of the minerals, many iron and manganese ores, most of the phosphorites, and combustible shales. Many metamorphic rocks (gneisses, schists, and marbles) first accumulated as marine deposits.
