As a result, deep-water massive sands of debris-flow origin are routinely misinterpreted as high-density turbidites.

Web30 de out. de 2012 · High-density turbidite deposits (T A, T B-2 and T B-3) have a tabular shape consistent with hindered settling, and are typically overlain by a more extensive drape of low-density turbidite (T D and T C,). This core and drape shape suggests that events sometimes comprise two distinct flow components. WebNeutron and density logs are important borehole measurements for estimating reservoir capacity and inferring saturating fluids.
