Muhammad Usman - Visiting Research Fellow - UCL | LinkedIn As in case of the Devonian and Silurian strata found within the Llano uplift, these strata represent brief periods of inundation of the region by shallow epicontinental seas and marine sedimentation alternating with long periods of terrestrial exposure during which these marine sediments were almost completely removed by erosion. Consult the figure below. Specific rock types (igneous, sedimentary, and metamorphic) are commonly found in specific geologic settings. [16][18][19], The only Mesozoic rocks that are known in the Llano region are those of the Cretaceous system. This is an example of, Clay minerals within a buried body of slate are recrystallized at high temperatures and pressures to form mica, producing a rock called phyllite. The image below shows metamorphism related to the emplacement of an igneous pluton. As stated, weathering, erosion and deposition is the natural process of breaking down and taking away the rocks and minerals. These processes can occur over an enormous range of timescales. Unit 4- Weathering, Erosion and Deposition. Once these sediments are separated from the rocks, erosion is the process that moves the sediments away from it's original position. AP human geography physical feature dictionary vocabulary. Desert Landforms. Depending on the size of the range and the local climate, uplift may persist until erosion rates or the strength of the crust limits the average elevation of the range from increasing any more. Chamberlin (1899). 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.
