SALINA PERIOD Meaning and
Definition
-
The Salina period refers to a geological epoch that spanned between 443.8 and 433.4 million years ago during the Silurian period. It is named after the Salina Formation, a prominent rock unit found primarily in North America. This period is defined by its distinctive sedimentary deposits, which consist predominantly of evaporites such as halite (rock salt) and gypsum. These evaporites formed due to the evaporation of shallow marine waters in a restricted basin environment.
During the Salina period, the Earth experienced a worldwide transgression, where sea levels rose and shallow seas covered extensive areas of the continents. This transgression led to the widespread depositions of marine sediments and the subsequent formation of evaporites.
The Salina period is significant in the geological history as it marks an important event known as the Ordovician-Silurian extinction event. This mass extinction, which occurred near the end of the period, resulted in the decline and disappearance of many marine species, particularly trilobites, brachiopods, and graptolites.
The Salina period provides valuable insights into the geological and paleontological history of the Earth. By studying the unique evaporite deposits and the fossils preserved within them, scientists can reconstruct past climate conditions, identify ancient marine ecosystems, and gain a better understanding of the processes that shape our planet.
