Sedimentary strata

Sedimentary rocks illuminate many of the details of the earth's history: effects of sea level change, global climate, tectonic processes, and geochemical cycles are all recorded in the sedimentary strata of the earth. Mesozoic strata are well preserved and exposed in the study area and are characterized by coal-bearing volcano- sedimentary formations containing abundant animal and plant fossils. Studies of Mesozoic strata in the northeast- ern NCC and the establishment of their lithostratigraphic sequence began during geological surveying in the 1960s– 1970s. observations of strata led him to formulate the Law of Superposition: in any sedimentary succession that has not been overturned, the oldest strata occur on the bottom. This may seem blatantly obvious, but as you will see shortly, this is an important and terribly useful rule for interpreting geological maps and perspective Find professional Sedimentary Strata videos and stock footage available for license in film, television, advertising and corporate uses.

B) Horizontal lava flows lie below the unconformity and horizontal, sedimentary strata lie above.
