Sedimentary Rocks - Canada Mines

Since sedimentary rocks have for the most part only been physically broken, they will usually retain some indication of the source rock – which as stated in the Igneous section – is important to mining exploration. Sometimes you may need a microscope to see it but the source rock is there.Sedimentary Rocks - Geology,There are three basic types of sedimentary rocks. Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris. Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate fromRocks and Minerals - Utah Geological Survey,How can sedimentary rocks tell you about Utah’s history?

Rock classification. Rocks are classified by their minerals and chemical make-up. The processes that formed them are also noted. Rocks may be igneous, sedimentary and metamorphic.Rock types may change in a so-called 'rock cycle'. Igneous rocks For the main article, see Igneous rock. Igneous rocks are formed when molten magma cools,Common Sedimentary Minerals - University of Pittsburgh,Thus, of the eight common igneous minerals, only quartz, K-feldspar, and muscovite are commonly seen in sedimentary rocks.
