These xenoliths include pieces of limestone, clastic sedimentary rocks, and gneiss. The Early to Middle Proterozoic Roraima Group consists of continental clastic sedimentary rocks. The sequence mainly comprises carbonate reef deposits and shallow marine clastic sediments. This area consists of a heterogeneous series of dominantly clastic sedimentary rocks. In sedimentary rocks, rare-earth elements in clastic sediments are a representation provenance. The Sava Folds largely exhibit Paleozoic and Triassic rocks, and clastic sediments. The northwestern block consists of clastic marine sediments of Late Cretaceous to Pleistocene age. Where clastic sediment inputs are small, biogenic sedimentation can dominate especially nearshore sedimentation. Devonian limestones were found in Telen River, East Kalimantan, as fragments within Paleogene clastic sediments. Zircon is present in most soils and clastic sediments. Deltas are dominantly composed of clastic sediment (in contrast to chemical). They generally consists of clastic and carbonate rocks. The northeastern block contains fine to coarse grained clastic marine rocks of Cenozoic age. The equations included here describe sediment transport for clastic, or granular sediment. Thus hydrocarbons formed in clastic environments exchange more than those in carbonate settings.
