Florence Bascom Geoscience Center
The primary mission of the Florence Bascom Geoscience Center (FBGC) is to provide detailed scientific data and assessments to support natural resource management, public safety, and national security. The FBGC specializes in:
Geologic mapping and hazards
Paleontology, stratigraphy, and environmental geology
Special geologic studies at the intersection of national security and mineral resources
USGS Scientists Help Address Conflict Mining

Cosmic dust reveals dynamic shifts in central Arctic sea-ice coverage over the past 30,000 years Cosmic dust reveals dynamic shifts in central Arctic sea-ice coverage over the past 30,000 years
Arctic sea-ice loss affects biological productivity, sustenance in coastal communities, and geopolitics. Forecasting these impacts requires mechanistic understanding of how Arctic sea ice responds to climate change, but this is limited by scarce long-term records. We present continuous 30,000-year reconstructions of sea-ice coverage from the Arctic Ocean based on measurements of two...
10Be/9Be and 26Al/10Be support a late Miocene burial age for basal Gray Fossil Site sediments 10Be/9Be and 26Al/10Be support a late Miocene burial age for basal Gray Fossil Site sediments
We provide 2 independent radioisotopic age estimates for cored basal sediments of the Gray Fossil Site using cosmogenic nuclides. The first estimate uses meteoric 10Be/9Be from the bottom of the GFS-1 core, as well as from modern local grasses, to constrain the deposition of basal GFS sinkhole complex sediments to 6.60 ± 0.85 Ma. We corroborated this age estimate using in-situ 10Be and...
Calcareous nannofossil biostratigraphy and floral response to environmental changes recorded in the Pliocene Yorktown Formation, southeastern Virginia, USA Calcareous nannofossil biostratigraphy and floral response to environmental changes recorded in the Pliocene Yorktown Formation, southeastern Virginia, USA
The Pliocene Yorktown Formation, deposited on the U.S. Mid-Atlantic Coastal Plain, has played an important role in advancing our knowledge of Pliocene paleoclimate. To refine the age and paleoenvironment of the Yorktown Formation, we analyzed the calcareous nannofossil assemblage and compared it with variations in lithology and calculated sea surface temperature (SST) from previous...

Task 3 - Geologic Mapping of the (other) Non-Coalition Glaciated States
The area encompassed by Task 3 comprises the non-coalition (other) states within the glaciated region, including Montana, North Dakota, South Dakota, Iowa, Kansas, Missouri, Nebraska, and New Jersey. The primary objective of Task 3 is to continue the compilation of existing and create new 1:500,000-scale Quaternary geologic maps for the region, and to conduct new 1:24,000-scale mapping in areas of...
