Basils due to
Ocean cracked from the middle, in the split, the hot magma plows from the crust, encounter seawater It is immediately to cool down to form a rock. The slurry is continuously emerging, and the new formation is extruded around the previously generated rock formation. After hundreds of millions of evolution, the older age is the largest, and the older rock is the smallest. Case. In fact, this crust evolution process has never stopped from the birth of the earth. In the long geological age, those collapsed have formed a large and small sea basis.
Basin Environment
In the wide ocean basin, since there is no light and temperature, the seabed animal group in the Daoyang is very rare, and the stock sediment is mainly Breeding the calcium and silicon skeleton of the top of the ocean surface to sink to the sea floor to form calcium soft mud and silica. In submarine sediments in depth greater than 4700 meters, a large distribution of manganese tuberculosis resources is found.
