Several Examples of Sedimentary Rocks

2021-6-5 · Limestone can be considered organic or chemical sedimentary rock. It is commonly made up of oceanic remains, calcite, and aragonite. It is very similar to dolomite however the big difference is that it dolomite contains magnesium. Limestone is used most commonly in architecture. This can include pyramids, buildings, and sculptures.

Chambers are also replaced by the dolomite at places. Planktons are broken at places and intact to broken ratio is about 3:1. Detrital quartz and dolomite are major non skeletal grains of this microfacies (Figure 5(d)). Quartz grains are generally sub rounded and silt sized. The quartz content generally ranges from 3% to 5%.

Our Dynamic Desert

Limestone consists dominantly of the mineral Calcite-CaCO3, whereas dolostone consists dominantly of the mineral dolomite-CaMg(CO3)2. Dolomite is typically a secondary mineral replacement of original calcite material. Ancient carbonate rocks like those in the Mojave region tend to be enriched in dolomite.
