Sediment are mechanically and/or chemically weathered rocks, they are unconsolidated materials. Present Research investigation conducted on the sediment of Coast line area of Markran. Six major areas selected for the collection of sediment sample which are Sur Bandar, Koh Mehdi, Ganz, Pishukan, Gwader and Jiwani. Total sediment sample stations are eighteen, out of which one station on the Sur Bandar, one station on Koh Mehdi, Three stations on Ganz, Three stations on Pishukan, Three stations on Gwader East Bay, Five stations on Gwader West Bay and Two stations on Jiwani. Latest scientific instrument and technique X-Ray Diffraction (XRD) used in this time for investigation of Minerals. Quartz, Kaolinites, Calcite are the common mineral found during this study. Calcite and Quartz are found throughout the targeted area of the coastal belt and a major area has Kaolinites during this research. Baratovite found in some places. These types of mineral into sediment are normally due to the weathering of pre-existing rock and transport by running water in rivers, Ocean currents. Other less common factors uses for transportation of sediments are wind, glaciers and landslides. River sediments originate by the erosion process of near surface, exposed igneous, metamorphic or sedimentary rock. The sediments are then deposited and form sedimentary rock.
