Stratigraphy, a branch of geology, is the science of describing the vertical and lateral relationships of different rock formations formed through time to understand the earth history. These relationships may be based on lithologic properties (named lithostratigraphy), fossil content (labeled biostratigraphy), magnetic properties (called magnetostratigraphy), chemical features (named ...Final answer.

Choose one: A. Radiometric dating can be used only if some uranium is present in a rock. B. Dating a mineral within a metamorphic rock gives the age when the rock cooled below the closure temperatures of that mineral. C. Dating a sand grain in a sandstone gives the age of the sandstone's formation. D.In comparing permeability by sedimentary formation, the permeability is lower in well 2 than in well 1 for each stratigraphic formation, contrary to the comparison based on the two formations together (Table 4.5). The reversal is caused by the variation in the thickness of sedimentations due to the back-stepping structure in the reef.the boundary surface between two rock bodies (as between two stratigraphic formations, between an igneous intrusion and adjacent rock, between two igneous rock bodies, or between rocks juxtaposed by a fault) correlation.Overview.

Stratigraphy organizes bodies of rock chronologically and spatially in accordance with their contained characteristics. It puts indirectly connected rock units together in a relationship. Stratigraphy is the substructure for remodelling the Earth's history. It also plays a part in solving general geological questions.
