Micrite limestone - csmgeo.csm.jmu.edu

Micrite is one of the most common carbonate rocks. Most of what people call " limestone" is largely or exclusively micrite. As with clay (shale) it is deposited in generally quiet water, and appears in any environment where those conditions exist. This specimen could have come from a tidal lake, or a subtidal lagoon, or some similar environment.

What are sedimentary rocks? Shale and limestone - Quatr.us ...

Before sedimentary rocks When the Earth was first forming, about six billion years ago, there weren't any sedimentary or metamorphic rocks. The only rocks were igneous rocks like quartz. These formed when melted silica, carbon, and other molecules cooled off and stuck together. More about igneous rocks What are metamorphic rocks? Lots more geology articles Erosion [.]

Shale Rock: Geology, Composition, Uses - thoughtco

Shale forms via compaction, typically from particles in slow or quiet water, such as river deltas, lakes, swamps, or the ocean floor. Heavier particles sink, ultimately forming sandstone and limestone, while clay and fine silt remain suspended in water.Over time, these fine particles settle and build upon each other, forming rock.

Geology of Alabama | Encyclopedia of Alabama

Calcite Through much of Alabama's geologic past, the state was covered by ancient oceans, swamps, and other near-shore environments. The sediment left behind in these environments composes most of the state's bedrock: limestone, sandstone, shale, and chalk. All of these deposits are economically very important to Alabama.

The Density of Common Rocks and Minerals - ThoughtCo

Rock Densities. Rock density is very sensitive to the minerals that compose a particular rock type. Sedimentary rocks (and granite), which are rich in quartz and feldspar, tend to be less dense than volcanic rocks. And if you know your igneous petrology, you will see that the more mafic (rich in magnesium and iron) a rock is, the greater its ...
