There are four types of sediment: cosmogenous (from outer space), volcanogenous (ash from volcanic eruptions), terrigenous (continents erosion and river runoff), and biogenous (skeletons of marine creatures). Sediments are classified according to their size. In order to define them from the smallest size to the largest size: clay, silt, sand ...The presence of limestone and ocean marine fossils at the top of these mountains is one of the key pieces of evidence cited that advanced the idea of plate tectonics (large chunks of the Earth’s surface moving over molten rock in the Earth’s core) when it was first proposed as a theory in 1915.

Limestone is a sedimentary rock made primarily from calcium carbonate, usually in the form of calcite and aragonite. Its grains vary in size and can consist of a variety of materials including shells, coral, and mud. It is typically off-white to gray in color and usually forms in shallow marine environments.Most limestone was formed in shallow marine environments, such as continental shelves or platforms, though smaller amounts were formed in many other environments. Much dolomite is secondary dolomite, formed by chemical alteration of limestone.Some parts of the ocean remain isolated and untouched, particularly marine national monuments. In fact, the country’s most precious sites in the ocean are protected by law, often to make it possible for researchers to better understand the ...of chalky limestone with pyritic, cherty strata in the lower part and interbeds of shale in the upper part (BARAKA T et al. , 1984, ABDEL HAMID, 1985 & GHANEM, 1985).

Limestone is mostly a biological rock that forms in clear, warm, and shallow marine waters. Limestone exists in various types and colors. Its composition varies slightly from one reserve to another, but all types contain calcium carbonate as the primary ingredient.Limestone origins. Limestone is a very common sedimentary rock consisting of more than 50% calcium carbonate. Although it occurs in many different forms, its origins can be traced back to either chemical or biochemical processes that occurred in the geological past, often tens to hundreds of millions of years ago. Rock - Electrical Properties: The electrical nature of a material is characterized by its conductivity (or, inversely, its resistivity) and its dielectric constant, and coefficients that indicate the rates of change of these with temperature, frequency at which measurement is made, and so on. For rocks with a range of chemical composition as well as variable … ….
