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 …Earth Sciences.

If the rock consists of transported grains it is called CLASTIC - "broken fragments." If individual crystals consist of interlocking crystals formed from direct precipitation for water it is considered NONCLASTIC. FEATURES IN SEDIMENTARY ROCKSThe sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. Sandstone has two different kinds.Travertine Classic. Travertine Classic is a dark beige travertine with a a striped structure, and delicate stains like linear watercolors, natural stone. Formed by precipitation of calcium carbonate. The main mineral is calcite.

Calcium Carbonate Calcium-carbonate-encrusted, ...Sedimentary rocks are formed by the lithification of inorganic and/or organic sediments, or as chemical precipitates. There are two types of sedimentary rocks: Clastic and Chemical Clastic sedimentary rocks form when existing parent rock material is weathered, fragmented, transported, and deposited in layers that compact,CHERT. Chert is a chemical precipitate formed by groundwater. Chert can also form by biochemical accumulation of silica-rich fossils in deep marine ...Sediments of all sorts may be lithified to become rocks. Clastic material typically comprises quartz and clays; less commonly other minerals. Minerals produced by chemical precipitation include clays, carbonates, sulfates, halides, zeolites, and chert. We name clastic sedimentary rocks based primarily on clast size.Compared to marble and granite, travertine is also more susceptible to weathering (e.g., chemical, physical, biological) due to its CaCO 3 content and porosity.

Sandstone is a clastic sedimentary rock comprised of sand-sized particles about .1 to .2 mm in size. It is usually tan, brown, or reddish in color, and often (but not always) displays noticeable layers. The sand grains are most often made of quartz, cemented together by calcite or silica. Cave deposits like stalactites and stalagmites are another form of chemical precipitation of calcite, in a form called travertine. Calcite slowly precipitates from water to form the travertine, which often shows banding.Examples of sedimentary rocks can be found around the world, but luckily, you don't have to travel.
