ALLUVIUM

QalFlood plain sands, silts, gravels, and clays. In the Pascagoula Riveralluvium, Chert gravel is exclusive to the basal portion. ThePascagoula River Alluvium is approximately 40 to 60 feet thick.Chert-bearing gravels were absent outside the Pascagoula River alluvium in the Gautier North Quadrangle. Quartz pea gravels were noted in the smaller second order streams.in the smaller second order streams.

Geology field checked in 2016 - 2017 using the 1982, Provisional Edition, United States Geological Survey (USGS) 7.5-minute topographic quadrangle, Universal Transverse Mercator projection, 1927 North American Datum, contour interval 5 feet. Universal Transverse Mercator projection, 1983 North American Datum. GRS80 spheroid. 1000-meter Universal Transverse Mercator 1983 datum grid ticks, zone 16, shown in red. January 01, 2018, magnetic declination in quadrangle center is 1°54' west of true north, ± 0°20' uncertainty, changing by 0°7' west per year.
