Crustal and lithospheric structure of the west Antarctic Rift System from geophysical investigations: A review Crustal and lithospheric structure of the west Antarctic Rift System from geophysical investigations: A review
The active West Antarctic Rift System, which extends from the continental shelf of the Ross Sea, beneath the Ross Ice Shelf and the West Antarctic Ice Sheet, is comparable in size to the Basin and Range in North America, or the East African rift systems. Geophysical surveys (primarily marine seismic and aeromagnetic combined with radar ice sounding) have extended the information provided...

Tectonic and sediment supply control of deep rift lake turbidite systems: Lake Baikal, Russia Tectonic and sediment supply control of deep rift lake turbidite systems: Lake Baikal, Russia
Tectonically influenced half-graben morphology controls the amount and type of sediment supply and consequent type of late Quaternary turbidite systems developed in the active rift basins of Lake Baikal, Russia. Steep border fault slopes (footwall) on the northwest sides of half-graben basins provide a limited supply of coarser grained clastic material to multiple small fan deltas. These...

Lithostratigraphy, petrography, biostratigraphy, and strontium-isotope stratigraphy of the surficial aquifer system of western Collier County, Florida Lithostratigraphy, petrography, biostratigraphy, and strontium-isotope stratigraphy of the surficial aquifer system of western Collier County, Florida
In 1996, seven cores were recovered in western Collier County, southwestern Florida, to acquire subsurface geologic and hydrologic data to support ground-water modeling efforts. This report presents the lithostratigraphy, X-ray diffraction analyses, petrography, biostratigraphy, and strontium-isotope stratigraphy of these cores. The oldest unit encountered in the study cores is an...

Geology of the Black Mingo Group (Paleocene) in the Kingstree and St. Stephen areas of South Carolina Geology of the Black Mingo Group (Paleocene) in the Kingstree and St. Stephen areas of South Carolina
Paleocene vertebrate remains from the areas of Kingstree and St. Stephen, South Carolina, come from the Rhems and Williamsburg formations of the Black Mingo Group. Sedimentary textures and fossils indicate that both units accumulated in shallow, nearshore marine, lagoonal, and deltaic depositional environments. Calcareous nannofossils and dinoflagellates indicate that the vertebrate...

Erosion, weathering, and sedimentation Erosion, weathering, and sedimentation
This chapter explains how a variety of nuclides have been applied to catchments throughout the world. One of the most exciting new approaches for quantifying the rate at which catchments erode is the measurement of in situ produced cosmogenic nuclides. The commonly applied nuclides for erosion rate measurements are 3He, 10Be, 26A1, and 36C1. Use of such nuclides was restricted to...

Oxic limestone drains for treatment of dilute, acidic mine drainage Oxic limestone drains for treatment of dilute, acidic mine drainage
Limestone treatment systems can be effective for remediation of acidic mine drainage (AMD) that contains moderate concentrations of dissolved O2 , Fe3+ , or A13+ (1‐5 mg‐L‐1 ). Samples of water and limestone were collected periodically for 1 year at inflow, outflow, and intermediate points within underground, oxic limestone drains (OLDs) in Pennsylvania to evaluate the transport of...

Ground-water age and atmospheric tracers: Simulation studies and analysis of field data from the Mirror Lake site, New Hampshire Ground-water age and atmospheric tracers: Simulation studies and analysis of field data from the Mirror Lake site, New Hampshire
The use of environmental tracers in characterization of ground-water systems is investigated through mathematical modeling of ground-water age and atmospheric tracer transport, and by a field study at the Mirror Lake site, New Hampshire. Theory is presented for modeling ground-water age using the advective-dispersive transport equation. The transport equation includes a zero-order source...
