Sedimen permukaan dasar laut di perairan Paciran dan sekitarnya umumnya mengandung magnetit, hematit, limonit, piroksen, amfibol, biotit, pirit dan rutil. Ragam mineral berat ini terdapat pada satuan lanau pasiran, pasir lanauan dan pasir. Unsur utama pembentuk mineral berat yang terlihat dari analisis kimia berupa SiO2, Al2O3, Fe2O3, CaO, MgO, K2O,Na2O dan TiO2. Selain terbentuk secara mekanik endapan mineral berat ini, terutama magnetit dan pirit sebagian terbentuk secara insitu. The surficial sediments Paciran waters and its vicinity consist of magnetite, hematite, limonite, pyroxene, amphibole, biotite, pyrite and rutile. These heavy minerals can be found in sandy silt, silty sand and sand. The major elements of these heavy minerals can be seen from the chemical analysis as SiO2, Al2O3, Fe2O3, CaO, MgO, K2O,Na2O and TiO2. Another mechanical processes of these heavy mineral deposits, especialy magnetite and pyrite, some are formed authogenically.

Placer Deposits

Bintan Island is one of the areas traversed by the Southeast Asian granitoid belt which is known to have the potential for heavy mineral placer deposits. Due to the dwindling presence of heavy mineral placer deposits in land areas, it is necessary to look for the potential presence of heavy mineral placer deposits in water areas. Searching for placer heavy mineral deposits accomodation in these waters requires subsurface mapping.The method used in this subsurface mapping is a single channel seismic method with a total of 179 lines in the direction of northeast – southwest and west – east. The results of this seismic recording are then interpreted the boundaries of the seismic facies unit and distributed using the kriging method. Furthermore, the thickness calculates by using the assumption velocity 1600 m/s.Based on the facies unit boundaries that have been interpreted, the quaternary sediments that formed in the study area are divided into 2 types of units, namely: Unit 2 which is estimated to be fluvial – transitional sediment, and Unit 1 which is estimated to be transitional sediment – shallow sea. There is also a difference in thickness patterns in these two units, where unit 2 shows a pattern of sediment thickening that resembles a paleochannel trending northeast – southwest, while unit 1 is relatively uniform.From the results of this study, it can be said that the area that has potential for heavy mineral placer  deposits is in the west - center of the southern waters of Bintan Island. Where the potential for heavy mineral placer deposits should be in the paleochannel deposits that are part of Unit 2.
