Roger Suthren Some of the links on this page are to sites in North America. Access to these is likely to be faster before noon, British time. These processes are just one small part of the Rock Cycle . The composition of a sediment may give evidence of tectonic setting .
Mechanical durability is also important.
Quartz is by far the most common of these stable, durable minerals, and the commonest component in clastic sediments. Mineralogically mature rocks are those which have undergone prolonged weathering, transport and reworking. In some cases, it may also be possible to recognize different types of the same mineral, such as varieties of quartz. Mineralogy of clastic rocks This page contains detailed information on the occurrence and recognition of minerals and other components in sedimentary rocks. It is also available as a paper handout.
