Carbonate rocks: limestones and dolomites. Limestones and dolostones (dolomites) make up the bulk of the nonterrigenous sedimentary rocks. Limestones are for the most part primary carbonate rocks. They consist of 50 percent or more calcite and aragonite (both CaCO 3).Dolomites are mainly produced by the secondary alteration or replacement of limestones; i.e., the mineral dolomite [CaMg(CO 3) 2 ...

In the vicinity of Kargil, these volcanics are dated as 110–90 Ma (K–Ar; Reuber et al. (1990)). The why do people get homesick Clastic sedimentary rocks are dominated by components that have been transported as solid clasts (clay, silt, sand, etc.). In contrast, chemical and biochemical sedimentary rocks are dominated by components that have been transported as ions in solution (e.g., Na + , Ca 2+ , HCO 3 – , etc.). SEDIMENTARY ROCK TEXTURES. In clastic sediments the sedimentary texture includes the grain size, rounding, and sorting of the grains, all of which are related to what happened to the sediment during the weathering-to-deposition process.Because the processes that lead to the formation of chemical sedimentary rocks do not involve the weather-to-deposition process, there is no widely agreed-upon ...Terranes Hai'an Range.
