Fluvial paleochannels
In geology, a palaeochannel, palaeovalley, or palaeoriver (US spellings paleo-) is the remnant of an inactive river or stream channel that has been filled or buried by younger sediment. The sediments that the ancient channel is cut into or buried by can be unconsolidated, semi-consolidated, consolidated or lithified. … See more A palaeochannel is distinct from the overbank deposits of currently-active river channels, including ephemeral water courses that do not regularly flow (such as the Todd River, Central Australia) because the See more There is a large palaeovalley underneath Anangu Pitjantjatjara Yankunytjatjara (APY lands) in the remote north-west of South Australia. See more • Sedimentology • Erosion • Ore genesis • Paleoshoreline • Placer mining • Uranium ore deposits See more Paleochannels form when river channels aggrade and so deposit sediment on their bed. For the channel deposits to be preserved, the flow … See more Palaeochannels are important to geology for a number of reasons: • Understanding movements of faults, which may redirect river systems and so form stranded channels … See more Palaeochannels can host economic ore deposits of uranium, lignite, precious metals such as gold and platinum, heavy minerals such as tin, tungsten, and iron ore preserved as paleo- See more WebJul 1, 1974 · The reach of the channel that has been S. A. SCHUMM most consistently cited as evidence for fluvial erosion is the "braided reach" in the central portion of the channel (Fig. 7). This reach is approximately 30km wide, and the individual bars are on the order of … WebMar 1, 1987 · Alternatively, the channel sinuosity may be estimated by Schumm's (1972) equation P= 3.5 F-27 where F is the width/depth ratio. Using the values of mean angular range as measured in the field, the estimated channel sinuosity (P) is 1.39, whereas from Schumm's equation it comes out to 1.23, which is about the same. my mobile groomer chattanooga
