Were do the cements that hold sediments together come from?

Answer 1

Sedimentary rocks come from the fragments of pre-existing rocks called sediments. There are three types of sedimentary rocks, each coming from different kinds of sediments. Clastic sedimentary rocks are created from the broken pieces of other rocks, while chemical sedimentary rocks form from mineral crystals like halite and gypsum

Answer 2

The cement is derived from silicate, carbonate, iron oxide, and clay minerals which are present in the water between the rock particles. As the water is squeezed out, these minerals form between the rock particles, in essence, tying them together into a new sedimentary rock.

Answer 3

They come from cementation which is when dissolved minerals are deposited in the tiny spaces among the sediments

Answer 4

Sediments are derived from the weathering of preexisting rocks.

Answer 5

Sedimentary rocks come from the weathering and erosion of other rocks or from the precipitation in an aqueous solution.

Answer 6

if the water contains dissolved minerals, the minerals can form crystals in the gaps. The gaps act as a "glue" that cements the grains together.

Answer 7

The cements which are produced during diagenesis are a result of chemical activity including water and groundmass under some pressure.

Answer 8

They are usually deposits of silt at ocean beds or where rivers slow down

Answer 9

The cement holding sedimentary rock particles together could be clay minerals, iron, silica, or calcite.

Answer 10

They are usually deposits of silt at ocean beds or where rivers slow down.
