Web30 de set. de 2015 · For example, because high-density turbidity currents are defined on the basis of three different concepts (i.e., flow density, grain size, and driving force), there are no consistent criteria for recognition of their deposits. As a result, deep-water massive sands of debris-flow origin are routinely misinterpreted as high-density turbidites. Arnold H. Bouma, Charles G. Stone, ed. (2000). Fine-Grained Turbidite Systems.

The distinction is … Ver mais Turbidites provide a mechanism for assigning a tectonic and depositional setting to ancient sedimentary sequences as they usually represent deep-water rocks formed … Ver mais • Contourite • Flysch • High-density turbidity currents (Lowe sequence) • Sediment gravity flows Ver mais Turbidites were first properly described by Arnold H. Bouma (1962), who studied deepwater sediments and recognized particular "fining-up intervals" within deep water, fine-grained shales, which were anomalous because they started at pebble conglomerates and … Ver mais Submarine fan models are often based on source-to-sink [S2S] concepts linking sediment source areas, and sediment routing systems to the eventual depositional … Ver mais Turbidite sequences are classic hosts for lode gold deposits, the prime example being Bendigo and Ballarat in Victoria, Australia, where more than 2,600 tons of gold have been … Ver mais
