Charcoal from bat guano in Cripps Mill Cave
(2024-08-20)
This is charcoal data extracted from a bat guano sediment core that was collected from Cripps Mill Cave in Tennessee, USA
Petrology, Geochronology and Tectonic Setting of Early Triassic Alkaline Metagabbros From the Eastern Pontide Orogenic Belt (NE Turkey): Implications for the Geodynamic Evolution of Gondwana's Early Mesozoic Northern Margin
(2022-12-07)
The Triassic geodynamic evolution of the Pontides Belt, which geographically corresponds to northern Anatolia, is still a matter of debate. We present and interpret geological, petrographical, geochemical, and geochronological ...
Magma-facilitated transpressional strain partitioning within the Sawtooth metamorphic complex, Idaho: A zone accommodating Cretaceous orogen-parallel translation in the Idaho batholith
(2022-10-29)
Structural data from metasedimentary rocks and geochronologic data from intrusive rocks in the Idaho batholith provide evidence for the relationship between deformation and magmatism in the northern U.S. Cordillera. The ...
The U.S. educational effort in unsaturated zone hydrology
(2022-10-29)
The region of the earth below the land surface and above the water-saturated zone plays a major role in determining the behavior of hydrologic systems. To help educators and other interested individuals evaluate and continue ...
Impact Gardening as a Constraint on the Age, Source, and Evolution of Ice on Mercury and the Moon
(2022-10-26)
We update an analytic impact gardening model (Costello et al., 2018, https://doi.org/10.1016/j.icarus.2018.05.023) to calculate the depth gardened by impactors on the Moon and Mercury and assess the implications of our ...
Natural arsenic contamination of Holocene alluvial aquifers by linked tectonic, weathering, and microbial processes
(2022-10-26)
Linked tectonic, geochemical, and biologic processes lead to natural arsenic contamination of groundwater in Holocene alluvial aquifers, which are the main threat to human health around the world. These groundwaters are ...
An 40Ar/39Ar thermochronology of the Ofoten-Troms region: Implications for terrane amalgamation and extensional collapse of the northern Scandinavian Caledonides
(2022-10-25)
Fifteen Ar-40/Ar-39 cooling ages are reported for metamorphic hornblende and muscovite from far traveled terranes constituting the Ofoten nappe stack of northern Norway. Eight cooling ages on hornblende range from 425 to ...
Reactive transport of trace elements and isotopes in the Eutaw coastal plain aquifer, Alabama
(2022-10-25)
We integrate groundwater geochemistry, mineralogy, and numerical modeling techniques to study the reactive transport of heavy metals and isotopes in the Eutaw coastal plain aquifer, Alabama. Geochemical data show that the ...
Generation of rising-tone chorus in a two-dimensional mirror field by using the general curvilinear PIC code
(2022-10-12)
Recently, the generation of rising-tone chorus has been implemented with one-dimensional (1-D) particle-in-cell (PIC) simulations in an inhomogeneous background magnetic field, where both the propagation of waves and motion ...
Gap Formation Around 0.5 Omega(e) in the Whistler-Mode Waves Due To the Plateau-Like Shape in the Parallel Electron Distribution: 2D PIC Simulations
(2022-10-12)
The power gap around 0.5 Omega(e) (where Omega(e) is the equatorial electron gyrofrequency) of whistler-mode waves is commonly observed in the Earth's inner magnetosphere, but its generation mechanism is still under debate. ...
Magnetic Reconnection Inside Solar Wind Rotational Discontinuity During Its Interaction With the Quasi-Perpendicular Bow Shock and Magnetosheath
(2022-10-12)
Using a three-dimensional global hybrid simulation, we investigate the formation and evolution of ion-scale magnetic reconnection inside an interplanetary rotational discontinuity (RD) owing to its interaction with the ...
Laser Ar-40/Ar-39 age constraints on Miocene sequences from the Bengal basin: Implications for middle Miocene denudation of the eastern Himalayas
(2022-10-10)
Petrographic, mineral-chemistry and subsurface studies reveal that orogenic sedimentation had already begun in the Bengal basin by the early Miocene. Laser Ar-40/Ar-39 age determinations were made for detrital muscovite ...
