Limestone environment.

The process of limestone formation typically occurs in shallow, warm, marine environments where the accumulation and compaction of sedimentary materials takes place over long periods of time. Limestone can also form from the evaporation of water in caves and other confined spaces.Changes in rock type: During a transgression, deeper water sediments, such as shale and limestone, are deposited over shallow water sediments, such as sandstone and conglomerate. During a regression, the opposite pattern is observed. ... Transgressions and regressions can have a significant impact on the environment and on human …Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg (CO 3) 2.

Shale is made of fine clay particles, and therefore indicates deposition in relatively still water. In contrast, sandstone is made of slightly larger grains and therefore deposition of sand can happen in water that is moving slowly. Limestone is often associated with essential carbonate minerals and contains variables of silica, clay, chalk, silt, sand, feldspar, pyrite, quartz, and considerable amounts of magnesium carbonate (dolomite). Most of the limestone forming environment is found in shallow water areas between 30 degrees north and 30 degrees south latitude.Limestone is a carbonate sedimentary rock consisting of calcium carbonate as the main constituent and magnesium carbonate as a secondary component.

Shale is the most common sedimentary rock, accounting for about 70 percent of the rock in the Earth's crust. Shale is a fine-grained rock made from compacted mud and clay. The defining characteristic of shale is its ability to break into layers or fissility. Black and gray shale are common, but the rock can occur in any color.
