Stalactites and stalagmites in caves are formed in the same way. Limestone rock is often riddled with caves because water and carbon dioxide dissolve the limestone. Chalk is a soft, white limestone containing the shells of foraminifera.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO 3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite. Under the conditions of metamorphism, the calcite in the limestone ...Knowledgeable people readily agree that both fossils and rock layers can and do form very rapidly. But there’s a catch. Fossils and rock layers are not just found “one at a time.” Rocks chock full of fossils are buried in layers stacked on top of one another, in places about two miles (three km) thick!

This fossil cold seep is of early Paleocene age, about 65 million years old. It has an outer shell of gypsum, visible around the left base. Its core is a jumbled mass of carbonate rock containing fossils of tubeworms, bivalves, and gastropods. Modern cold seeps are very much the same.Rock layers are also called strata (the plural form of the Latin word stratum ), and stratigraphy is the science of strata. Stratigraphy deals with all the characteristics of layered rocks; it includes the study of how these rocks relate to time.
