Neritic sediments of the Merrimack Embayment (ANAN71 shapefile)

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.

梅里马克湾（Merrimack Embayment）的海岸沙丘、海滩及内陆浅海带（inner neritic zone）构成一个岩石学省。除重矿物分析外，多数样品均开展了粒度统计工作。借助统计参数散点图可区分浅海沉积物与海滩沉积物，但统计参数无法有效区分河流沉积物与浅海沉积物。
