Step 1: List each of the geologic features shown in Figure 9.12 from youngest (1) to oldest (8). Unconformities (i.e., angular unconformity, disconformity, and nonconformity) are indicated by a wiggly line between rock layers. Rock units A, D, E, and F are sedimentary Rock units B and C are igneous. Rock unit G is metamorphic.Conglomerate is a clastic sedimentary rock that shaped from rounded gravel and boulder sized clasts cemented or in a matrix supperted. The rounding of the clasts show that rocks have been transported a long way from their source or on a seaside tide to wave movement.

By Christine Wilkerson. To classify and map layers of rock, geologists created a basic unit called a formation. A formation is a rock unit that is distinctive enough in appearance that a geologic mapper can tell it apart from the surrounding rock layers. It must also be thick enough and extensive enough to plot on a map.YENİ WEB SİTESİ. Web Sitemiz Yeni Arayüz Tasarımı İle Siz Değerli Kullanıcılarımıza Hizmet Vermektedir. 24 / 05 / 2017.
