From those informations, we can construct the facies model that’s a general summary of the characteristics of certain depositional system. Environmental analysis is based on properties of rocks that have environmental significances, which are sediment structures, textures, fossils and sedimentary facies associations. To gain the depositional environment, we need to do environmental analysis. Thus, depositional environments are important and essential not just in sedimentology, but also in other geological disiplines, such as stratigraphy. In sedimentology, determining the depositional environments from the properties of sediment or sedimentary rocks is the main purpose and focus. Depositional process and the properties of rock has really close genetic relationship. The properties of sedimentary rocks such as sediment textures and structures, are formed by chemical, physics and biological processes. These 5 processes with 4 types of rocks make up a cycle that is known as sedimentary cycle. Sedimentary rocks are formed by 5 processes, there are erosion, weathering, transport, deposition, and diagenesis process (Boggs, 1991). ![]()
