Neritic sediments of the Merrimack Embayment (ANAN71 shapefile)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-05-12T00:00:00Z
The coastal dunes, beaches, and inner neritic zone of the Merrimack Embayment constitute a petrologic province. In addition to heavy mineral analyses, grain size statistics were generated on most of the samples. Neritic and beach sediments can be differentiated using scatter plots of statistics, but statistical parameters are ineffective in differentiating between river and neritic sediments.
