Holocene reworking of a sand sheet in the Merrimack Embayment, Western Gulf of Maine Holocene reworking of a sand sheet in the Merrimack Embayment, Western Gulf of Maine

Recent bathymetric, backscatter, and seafloor sediment samples demonstrate that a large sand sheet was formed in the inner shelf by the reworking of the Merrimack River lowstand delta (deposited 12 kya; currently at 45 m depth) and braid plain during the Holocene transgression. Asymmetric bedforms and distinct grain size distributions suggest the sand sheet is actively being reworked by...

Overview: The Chemehuevi Formation along the lower Colorado River Overview: The Chemehuevi Formation along the lower Colorado River

A distinctive set of fine-grained deposits occurs throughout the lower Colorado River Valley, extending from just below the mouth of Grand Canyon to well into the river delta below Yuma, AZ (Figure 1), an along-channel distance of over 700 km. Upstream of Parker, Arizona, the deposits consist of scattered erosional remnants up to 150 m above the modern floodplain. Below Parker, they...

Stratigraphy of Colorado River deposits in lower Mohave Valley, Arizona and California Stratigraphy of Colorado River deposits in lower Mohave Valley, Arizona and California

Deposits in lower Mohave Valley and upper Topock Gorge near Topock, Arizona and Park Moabi, California record a succession of depositional and erosional events since late Miocene time that relate to the development of the Colorado River. Upper Miocene alluvial fans were deposited toward a depocenter east of the present valley bottom, indicating there was no valley outlet then through the...
