Pildian

Pildian is a geological term used to describe a type of sedimentary rock formed during the Permian-Triassic period. The name Pildian refers to a specific geological formation in Estonia, which is characterized by a unique combination of sedimentary rocks.

Geologically, Pildian rock formations are classified as shallow marine sediments, deposited in a shallow sea environment. The rocks are composed of a variety of sedimentary materials, including quartz sand, limestone, and dolomite. They are often rich in fossils of marine organisms, such as corals and brachiopods.

Pildian rocks are an important part of the geological record, as they provide information about the environment and climate conditions of the Earth during the Permian-Triassic period. This period was a time of significant geological upheaval, with the supercontinent of Pangaea beginning to break apart and the start of a prolonged period of volcanic activity.

The Pildian geological formation spans a large area, including parts of Estonia, Latvia, and Russia. In Estonia, it is particularly well-represented in the northeastern and eastern regions. The formation is thought to have originated during the initial stages of the rifting of the supercontinent of Pangaea.

Pildian rocks have been studied extensively, providing valuable insights into the geological and climatic history of the region. Further research is ongoing to determine the full extent of the Pildian formation, as well as its relationship to other geological formations in the area.
