Exhalative Deposit - an overview | ScienceDirect Topics

Sedex deposits generally form in restricted sedimentary basins or half grabens bounded by syn-sedimentary growth faults. The exhalative vents generally occur along the faults and the exhaled brine accumulates in adjacent seafloor depressions. As Sangster (2002) points out, most Sedex deposits are vent-distal.
