High density turbidite

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.
