What minarals are in sedimentary rocks?

Answer 1

Fossils ranging in size from single celled plant and animal organisms to whale bones to dinosaur footprints are found in sedimentary rock.

Answer 2

There are lots of different types of sedimentary rocks: Gravel, sandstone, shale, limestone, etc. Let's talk sandstone. Sandstones generally contain small grains of feldspar and quartz. The area between the grains is called porespace and can contain cement (calcium carbonate or silica), clay, water or oil. Other types of grains found in sandstones can be: limestone fragments, metamorphic rock fragments, sandstone fragments, fossils, and other minor constituents such as magnetite, zircon, anhydrite, mica, etc. Gravel is coarser grained than sandstone and usually contains rock fragments eroded from older rocks. Shale is very fined grained and is usually contains clay minerals. Limestones are made up of calcium carbonate (calcite) that is usually formed by marine organisims (corals, shells, etc.).

Answer 3

Common minerals found in sedimentary rocks include quartz, feldspar, calcite, and clay minerals. Additionally, minerals like gypsum, halite, and dolomite can also be present in certain sedimentary rocks. The specific minerals present depend on the composition of the original source material and the depositional environment in which the rock formed.

Answer 4

Fossils ranging in size from single celled plant and animal organisms to whale bones to dinosaur footprints are found in sedimentary rock.

Answer 5

Fossils are very commonly found in sedimentary rocks more than other rocks. It can be composed of sand, decomposed other rocks and parts of hills or mountains and possibly fish bones.
