Sedimentary rocks names
In this course you will learn to describe clastic sedimentary rocks in order to better understand how and where they were formed. Geoscientists may be trying to match rocks from one location to another. Rocks seen at two different outcrops may have the same name (for example, sandstone), but this is far from enough information for a geologist ... Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks. As discussed in the “Earth’s Minerals” chapter, dissolved ions in fluids precipitate out of the fluid and settle out, just like the halite in Figure below. The evaporite, halite, on a cobble from the Dead Sea, Israel.

42 6.2 Chemical Sedimentary Rocks . Whereas clastic sedimentary rocks are dominated by components that have been transported as solid clasts (clay, silt, sand, etc.), chemical sedimentary rocks are dominated by components that have been transported as ions in solution (Na +, Ca 2+, HCO 3 –, etc.).There is some overlap between the two because …Sedimentary rock - Classification, Deposits, Types: In general, geologists have attempted to classify sedimentary rocks on a natural basis, but some schemes have genetic implications (i.e.,knowledge of origin of a particular rock type is assumed), and many classifications reflect the philosophy, training, and experience of those who propound them.Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, ...
