Stratigraphy is the scientific study of rock layers and when these layers were created. It is basic to geology and is used in many fields, including archaeology and petroleum geology, or the search for hydrocarbons. Stratigraphy involves the study of how and where rock layers move under various conditions. It primarily focuses on sedimentary rock—which accounts for about 75 percent of the surface of continents—and is closely linked to sedimentology but may involve other types of rock, such... więcej

The earth's magnetic field has fluctuated between a polarity like that of today's field (“normal”) and one completely opposite (“reversed”) thousands of times in the last 600 million years. The magnetic minerals in erupting lavas and in settling sediments align with the prevailing field at the time the rock forms, thereby recording the earth's polarity history. The pattern of polarity changes in a thick sequence of rock and can be matched from area to area, providing... więcej

Biostratigraphy is that branch of the study of layered rocks—stratigraphy—that focuses on fossils. Its goals are the identification and organization of strata based on their fossil content. Biostratigraphy thus investigates one of the principal bases of the geologic time scale of earth history.
