U-Pb zircon data for: Cretaceous plutonic rocks of western Glacier Bay National Park and Preserve U-Pb zircon data for: Cretaceous plutonic rocks of western Glacier Bay National Park and Preserve
In 2016, with National Park Service support, several previously undated plutons were sampled in Glacier Bay National Park and Preserve along the west side of Glacier Bay for age determinations. Geochronologic analyses were conducted to determine the ages of the plutonic rocks in the Glacier Bay area. Five samples were collected by Frederic Wilson (USGS Alaska Science Center), from Dundas...
U-Pb detrital zircon data for: Select Pennsylvanian-Triassic sedimentary rocks from Colorado U-Pb detrital zircon data for: Select Pennsylvanian-Triassic sedimentary rocks from Colorado
This dataset includes U-Pb detrital zircon age data for samples from the Ingleside and Lyons formations in north-central Colorado collected from Owl Canyon and Park Creek Reservoir, from the Molas and Hermosa formations in southwestern Colorado collected from Molas Pass, and from the Lykins formation and its equivalents along the Front Range and in southeastern Colorado. It accompanies
U-Pb detrital zircon data for: lower Paleozoic sedimentary rocks near Silverton, CO USA U-Pb detrital zircon data for: lower Paleozoic sedimentary rocks near Silverton, CO USA
This Laser ablation ICPMS U-Pb detrital zircon data set supports mapping and stratigraphic interpretations of the Upper Devonian Ignacio Formation in southwestern Colorado (Silverton area). All samples were collected from a measured stratigraphic section called "Sultan Creek South" located at 37.710010 and -107.67530 (Evans and others, 2019). The Ignacio Formation was previously...
U-Pb detrital zircon geochronology of cores and cuttings from selected wells in Arctic Alaska U-Pb detrital zircon geochronology of cores and cuttings from selected wells in Arctic Alaska
Select samples were collected from boreholes in Arctic Alaska to determine the U-Pb ages of zircon to determine a maximum depositional age of the geologic units and/or provenance of the zircon in the samples. Samples were collected from the Department of Natural Resources-Alaska Geologic Materials Center in Anchorage Alaska and sent to U.S. Geological Survey-Geology, Geophysics and...
U-Pb zircon data for: The Poncha Pass and Deadman Creek areas, northern Sangre de Cristo mountains of south-central Colorado U-Pb zircon data for: The Poncha Pass and Deadman Creek areas, northern Sangre de Cristo mountains of south-central Colorado
Geologic mapping, characterization of geologic structures, and sampling for geochronology was completed in two areas of the northwestern Sangre de Cristo mountains from 2011 through 2017. This data release provides the raw analytical data, metadata and sample information for 20 zircon U-Pb age analyses from laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS). The two...
