Geological Evolution of the Earth's Crust in Ukraine

The geological evolution of the Earth's crust in Ukraine can be divided into several major eras. These eras represent different periods of time during which geological processes shaped the land and formed the Earth's crust. The eras are as follows:

A. Archean Era: The Archean Era is the oldest era in the geological history of Ukraine. It spans from approximately 4 billion to 2.5 billion years ago. During this era, the Earth's crust was forming, and the first continents were beginning to take shape. The rocks formed during this era are primarily composed of granite and gneiss [[1]].

B. Paleozoic Era: The Paleozoic Era occurred from approximately 541 million to 252 million years ago. It is characterized by the development of marine life, including the appearance of early fish, plants, and insects. In Ukraine, the Paleozoic Era is marked by the formation of sedimentary rocks, such as limestone, shale, and sandstone. These rocks can be found in various regions of Ukraine, including the Carpathian Mountains and the Dnieper-Donets Basin [[2]].

C. Mesozoic Era: The Mesozoic Era took place from approximately 252 million to 66 million years ago. It is often referred to as the "Age of Dinosaurs" due to the dominance of these reptiles during this time. In Ukraine, the Mesozoic Era is associated with the formation of sedimentary rocks, including limestone, sandstone, and clay. Fossils of dinosaurs, marine reptiles, and other prehistoric creatures have been discovered in various regions of Ukraine, such as the Crimea Peninsula and the Donetsk Basin [[3]].

D. Cenozoic Era: The Cenozoic Era began approximately 66 million years ago and continues to the present day. It is the most recent era in the geological history of Ukraine. During this era, the Earth's climate and ecosystems underwent significant changes. In Ukraine, the Cenozoic Era is characterized by the deposition of sedimentary rocks, such as sand, clay, and gravel. These rocks can be found in various regions of Ukraine, including the Dnieper-Donets Basin and the Black Sea coast [[4]].

In summary, the geological evolution of the Earth's crust in Ukraine can be divided into the Archean, Paleozoic, Mesozoic, and Cenozoic eras. Each era is associated with different geological processes and the formation of specific types of rocks.
