WebThis process is called sorting. 5. Poorly sorted sediments were probably not transported very far from their source rock by currents. Well-sorted sediments were either carried long distances by currents and/or were extensively winnowed in ... An aid to determining whether sediments have been transported long distances is by examining the shapes ... Webwith the mean diameter of 300 lm or so are still not well sorted, lists the grain size distribution of the sediments in the depths of 6.60–6.80 m. The formation of zibar in the Kumtagh desert in-volves wind flow, sand characteristic, existence of linear dunes with relative large spatial scales, and underlying fluvial deposition etc.
WebPorosity in sediments that contain a mix of coarser- and finer-grained components varies as a function of the porosity and volume fraction of each component. We considered sediment mixtures representing poorly sorted sands and gravely sands. We expanded an existing fractional-packing model for poros … WebPorosity in sediments that contain a mix of coarser- and finer-grained components varies as a function of the porosity and volume fraction of each component.
