Sedimentary rock
Sedimentary rock
Breccia is the type of sedimentary rock that is made of other fragmented rocks. The mineral that holds the fragments together can be made from the same rock material as the larger fragments, or from a different type of rock entirely.
A sedimentary rock is formed when rock fragments are compacted and cemented together by pressure and minerals. Examples of sedimentary rocks include sandstone, shale, and conglomerate.
Clastic sedimentary rocks are formed from the accumulation of rock and mineral fragments, while chemical sedimentary rocks are formed from the precipitation of minerals out of solution. Organic sedimentary rocks are formed from the remains of plants and animals. They differ in their composition, formation process, and appearance.

The precipitation of minerals forms chemical sedimentary rocks. Examples include calcite deposits in vesicles in igneous rocks like pumice. The definition may be extended to include rocks formed by evaporation. Mineral Gypsum is formed this way.
Sedimentary rock, specifically a type known as conglomerate, is formed when small pieces of other rocks are deposited in layers and cemented together by dissolved mineral material. This process can result in a rock with a varied composition and appearance due to the assortment of rock fragments present.
Epidote is formed from a set of minerals, and it is used to form other mineral types of its own kind by chemical reactions on it.
The first kind to settle in Alberta were the Cree and Blackfoot peoples.
Detrital sediment consists primarily of mineral grains that were eroded from rocks on land. These mineral grains are transported by wind, water, or ice and eventually settle and accumulate to form detrital sedimentary rocks, such as sandstone or shale.
In the desert, the winds transport sediment near the surface through a process called saltation. This is because the deserts have no or very little soil moisture to hold the mineral and rock fragments.
