Detrital Mineral Composition of the Sediments from Huanghe and Its Hydrodynamic Environmental Constraints
The composition of detrital minerals of the sediments from Yellow River mainstream and major tributaries are similar in general, albeit certain variation between different rivers. The main assemblages of heavy minerals are opaque minerals-garnet-epidote-carbonate and altered minerals. As a whole, the mineral compositions are not only controlled by their sources, but also constrained by seasonal hydrodynamic intensity of the river and the mineral gravity differentiation induced by sedimentary environment changes. It should be careful to identify sediment sources in the marginal sea just based on the mineral assemblages of the river, such as Yellow River.
