<![CDATA[Sedimen di sepanjang pantai Kabupaten Rembang terdiri atas sedimen muda (aluvial) dan sedimen tua (breksi dan batugamping). Sedimen muda merupakan sedimen lepas dan terdapat di daerah sedimentasi. Sedimen tua berupa sedimen kompak yang secara fisik mempunyai resisitensi tinggi terhadap abrasi Batuan yang terdapat di kawasan pesisir adalah: pasir kuarsa, andesit, tras kaolin, batugamping, batubara dan lempung. Peta sebaran sedimen dasar laut perairan Kabupaten Rembang, menunjukkan dominasi endapan pasir, lanau (pasir halus) dan lanau pasiran (pasir halus - kasar). Kandungan mineral yang terdapat di perairan Kabupaten Rembang terdiri dari: magnetit, pirit, hematit, zirkon, ilmenit diopsid, augit, hornblende, kuarsa, biotit, muskovit dan dolomit Kata Kunci: sedimen, mineral, Rembang The coastal sediment along the coastal of Rembang District consists of young sediment (alluvium) and old sediment (breccias and limestones). Young sediment is placer sediment that occupies the sedimentation area. Old sediment is massive sediment that has a high resistance to abrasion Rocks content in the coastal zone area consist of quarzt sand, andesite, caoline, limestone, trass, coal and clay. Seafloor surficial sediments map of the Rembang water area shows the domination of sand deposits, silt (fine sand) and sandy silt (fine to medium sand). Mineral content in Rembang waters area consists of magnetites, pyrites, hematites, zircons, ilmenite diopsides, augitse, hornblendas, quartzs, biotitse, muskovites and dolomites.
