Sediments produced by the erosion filled some valleys within the park and spilled outside the Hills to the east, forming the layers now visible at Badlands National Park. Identify the correct steps in the transformation of a sedimentary rock into a metamorphic rock. Deposition of Cambrian through Cretaceous sediments occurred on the eroded PreCambrian metamorphic and igneous rock of the Texas Hill Country. What process(s) would be responsible for the transition labeled C? The removal by erosion of large volumes of rock from high altitude and its deposition elsewhere can result in a lightening of the load on the lower crust and mantle that can cause isostatic uplift. A buried body of shale is subjected to differential stress, causing clay minerals to realign and produce slate. Rocks and Unconsolidated Sediment. Deltas-when a river flows into an ocean, the river slows down and deposits the sediment it was carrying. The uplift of the Himalaya Mountains and resulting increased weathering has been cited as a principal cause of late Cenozoic cooling due to a drop in CO2 (Raymo, 1991). wind weathering. Answer (1 of 2): As with most things in geology the answers is it depends. the competence of rocks is considered as a controlling factor while weathering and erosion are termed as the decaying parameter. Each of these domains contain distinctive rock types and ages and were either erupted, intruded, or deposited in three separate areas and later tectonically juxtaposed during the Grenville Orogeny.
