Question details

may provide agments) 4. Each of the following diagrams illustrates a different tectonic setting. Areas in A and B are tectonically active haracterized by high relief. A shows a volcanic arc associated with subduction. B shows and, therefore, are c a thrust-faulted mountain belt which formed during a continent-continent collision. The mountains in B are dominated by sedimentary a or no active tectonism and, therefore, an area of low relief. Rocks exposed in this example are very old gran- ites and granitic gneisses. nd metasedimentary rocks. The area in C is a stable craton where there İs little A. What types of sands would you expect to be produced from these source areas-quartz sands, feldspathic sands, or lithic sands? In the case of lithic sands, what types of rock fragments would be common? SETTING Volcanic Arc | SAND TYPE TYPE OF LITHIC FRAGMENTS (if any) Collisional Orogen Stable Craton B. How might sand composition change if the stable craton was to experience a rifting event that produced up- lifted blocks and downdropped basins (normal-faulted basins)?
