Deposits of all 12 geological periods from the Kembrian (570 mln years
ago) have been discovered on the territory of Kazakhstan. Palaeontological collection consists of approximately thirteen thousand articles of the Earth history; the oldest one is wavy-surf ripple (500 mln years). The sandstone plate preserved clear imprints of alder-tree leaves, conifers, grass sterms and leaves. It is evidently that about 500 mln. years ago leaves of trees and bushes, growing round stagnant reservoir with considerable concentration of ferric salt in water, felt in it. Owing to the calm condition of water and sufficiently low temperature in reservoir leaves had been preserved. By the time they were covered with silt and splendidly kept in sedimentary rocks. |
