    2021-12-18 · Clastic sedimentary rocks are the group of rocks most people think of when they think of sedimentary rocks. Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped.

    Abstract. The accumulation of rockfall talus slopes has been studied for conditions in which stones are added relatively slowly, so that dynamic interactions between them may be ignored, and stone movements modeled "one-at-a-time." Laboratory scale models (1 m long) are compared with the results of mathematical and computer simulation.
