The Holocene Officially divided into three periods. The International Commission on Stratigraphy (ICS) </strong></p> <p> has officially classified the last 4200 years as a distinct geological period in the history of our planet. It was named Magadaskara period. </p> <p> To obtain a distinct line in the official classification of the geological period must reflect all events that have implications on a global scale that has led to the formation of a new layer of rock. </p> <p> One of the most obvious boundaries existed 66 million years ago, when the Cretaceous gave way to the Tertiary (on a modern scale, it includes several periods): sedimentary rocks separated by a layer of high iridium content, scattered We live in the Holocene epoch, which began 11.7 thousand years ago – after a major global warming led to the end of the last ice age . But the Holocene is now also divided into several geological periods: the early phase, the intermediate phase and the late phase. </p> <p> Each phase was preceded by a major climate change. The last is the Magalasi period begun 4200 years ago with the great drought, whose disastrous consequences were felt for two centuries and caused irreparable damage to the civilizations of Egypt, Greece, Syria, Palestine, Mesopotamia, Valley from the Indus and Valley of other periods of Magalasi geological scale different in that its beginning coincided with the overall development of the culture, which was caused by the same climate changes. </p> <p> The Magalasi period is distinguished by the presence of specific chemicals the most obvious compounds can be observed in the stalagmitic deposits in the caves of the state of Meghalaya in northeastern India </p> <p> The intermediate phase from the Holocene, Mahalaxmi before, called Northrupthu and began 8300 years ago with the cold. It caused the rapid and massive melting of glaciers in modern Canada, which made the world's oceans huge amounts of fresh water, changing ocean currents. The first Holocene period, occurring after the end of the Ice Age, named Greenland. </p> </p></div> </pre> </pre> [ad_2] <br /><a href=Source link
