Turbidite. Turbidites can be defined by sediment samples or deduced (e.g., distal end members in deep areas affected by mass-transport deposits, sheet-like turbidites and megaturbidites) by stratified reflections with high acoustic amplitudes and lateral continuity and by prominent transparent layers bounded at the base by a relatively high acoustic احصل على السعر
