Sediment

Episode 2 of Sedimentology introduces sediment, the fundamental material studied in this field. Building upon the basic understanding of sedimentology, we will explore the sources of sediment, the processes that create it, and its various forms. We will discuss the different types of sediment, including clastic, chemical, and biogenic, and their characteristics. This episode lays the groundwork for understanding how sediment is transported, deposited, and eventually transformed into sedimentary rocks, which will be covered in future episodes.

Building on our understanding of *sediments*, *sedimentary environments*, and *facies*, this episode explores the specific locations where sediments accumulate. A **depositional environment** encompasses the unique physical, chemical, and biological conditions influencing sediment deposition. We will categorize these environments into three major groups: **continental**, **transitional**, and **marine**. You'll learn about characteristic settings within each group, such as rivers, deserts, beaches, deltas, and the deep sea, and how the processes within these environments lead to distinct sedimentary deposits (facies). Understanding these environments is key to deciphering Earth's geological past recorded in sedimentary rocks.
