Description
Summary:Plate tectonics history provided an opportunity to geologists to reconstruct some stages in evolution of our planet and distinguish ancient continents—Arctic and Nena, supercontinents of Columbia, Rodinia amd Pangea, as well as to position them on the Earth's surface. More than billion years (1.85-0.65Ga) the ancient Baltica continent was rather close to Greenland. The youngest su-perconrinent started to be formed about 450Ma BP and ended 250Ma BP, when Baltica was close to Greenland again. Therefore, Lithuanian geologists are interested not only in Quaternary geology of Greenland, but also in older rocks, since mechanisms and rime of rock formation were similar. In 2006 the author took part in the expedition of Lithuanian geologists to Greenland, where she was concerned with crystalline rock origin and age.
