When igneous rocks are exposed to weathering, many of their common minerals completely dissolve or partially dissolve and convert into clay minerals. As a result, olivine, pyroxene, plagioclase, amphibole, and biotite are uncommon in sedimentary rocks.yrite is not a rock-forming mineral, but it is commonly present in sedimentary rocks that formed in or near seawater (oceans, lagoons, and coastal swamps).

Detrital refers to mineral grains and rock fragments, such as sand grains or pebbles, that are produced during the weathering process and transported to the site of deposition as particles. The most abundant detrital minerals in sediments are quartz and clays. Quartz is an abundant mineral in many rocks.hus quartz can be thought of as a residual mineral, left over and concentrated in detrital sediments after the other rock-forming minerals, such as feldspars and ferromagnesians, have been decomposed. Clays are major components of shales and mudstones but are rarely abundant in other common rocks.

Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. A clast is a fragment of geological detritus, chunks and smaller grains of rock broken off other rocks by physical weathering.lastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock.

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.The other four minerals are salts that precipitate as water evaporates. The elemental constituents of these salts are ultimately also derived from mineral weathering.yrite is not a rock-forming mineral, but it is commonly present in sedimentary rocks that formed in or near seawater (oceans, lagoons, and coastal swamps).

Sedimentary rocks are types of rock that are formed by the deposition of material at the Earth 's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral and/or organic particles (detritus) to settle and accumulate or minerals to precipitate from a solution.Particles that form a sedimentary rock by accumulating are called sediment.Before being deposited, sediment was formed by weathering and erosion in a source area, and then transported to the place of deposition by water, wind, ice, mass movement or glaciers which are called agents of denudation.ost sedimentary rocks contain either quartz (especially siliciclastic rocks) or calcite (especially carbonate rocks). In contrast to igneous and metamorphic rocks, a sedimentary rock usually contains very few different major minerals.

Detrital Rocks-these rocks have a clastic texture, that is they are composed of fragments compressed and cemented together. In detrital rocks, the clasts are fragments of detritus, the product of weathering of pre-existing rocks.Non-detrital rocks-these rocks can have clastic or crystalline textures.They are made from materials which did not directly result from the weathering of other rocks.alcite: calcite forms and is stable at the Earth's surface. Some calcite is formed from precipitation, but much of the calcite in sedimentary rocks is formed by biological activity. Many marine organisms secrete skeletal material (shells) of calcite.

Clastic sedimentary rocks are composed of silicate minerals and rock fragments that were transported by moving fluids (as bed load, suspended load, or by sediment gravity flows) and were deposited when these fluids came to rest.ost sedimentary rocks contain either quartz (especially siliciclastic rocks) or calcite (especially carbonate rocks). In contrast to igneous and metamorphic rocks, a sedimentary rock usually contains very few different major minerals.

The formation of a clastic sediment and sedimentary rocks involves five processes: 1  Weathering-The first step is transforming solid rock into smaller fragments or dissolved ions by physical and chemical weathering as discussed in the last lecture.uch material, called detritus, consists of fragments of rocks and minerals. When the energy of the transporting current is not strong enough to carry these particles, the particles drop out in the process of sedimentation.
