Irrigator Responses to Changes in Water Availability in Idaho's Snake River Plain
… changes in water availability in Idaho's Snake River Plain over the past 33 years. Google Earth Engine's high performance cloud computing and big data processing capabilities were used to compare the performance of three spectral indices, three compositing algorithms and two sensors for …

Evaluation of Paleo-climate for the Boise Area, Idaho, from the last Glacial Maximum to the Present Based on delta 2H and delta 18O Groundwater Composition
… and divides the batholith from the western Snake River Plain. The Nampa-Caldwell system is in the volcanic, fluvial and pluvial sediments of the western Snake River Plain. Groundwater ages for these systems are modern, 5-15 ka, 10-20 ka, and 20-40 ka respectively. Local meteoric water lines …

Late Cenozoic basalts from the Basin-Range province, western United States
… Cenozoic basalts from adjacent regions (Columbia River Plateau, Snake River Plain, Yellowstone area, High Cascades and Sierra Nevada) are predominantly tholeiitic. This apparent petrologic provincialism is supported by complementary variations in heat flow, seismic velocities, crustal thickness, …

Testing the hypothesis of the slab-plume interaction on the formation of the Yellowstone hotspot system
… province that includes the mid-Miocene Columbia River flood basalt (CRFB) and subsequent Yellowstone and Newberry hotspot tracks. We find that the sinking slabs dominate the buoyancy and dynamics of the system, and that evolution of the mantle upwelling is subject to that of the slabs. Our …

Microstructural evolution of silicate immiscible liquids in solidifying ferrobasalts
… tholeiitic basaltic glass from Hawaii (USA), the Snake River Plain (USA), and the Laki eruption (Iceland). High-resolution imaging, electron probe microanalysis, and atom probe tomography are combined to examine the role played by compositional boundary layers in promoting unmixing around growing …

Variations in δ56Fe during magma differentiation at Cedar Butte volcano: signatures of thermal diffusion?
The Snake River Plain (SRP) is a volcanically active region lying along the Yellowstone hot spot track. Cedar Butte is a SRP volcanic complex which erupted a compositional progression of lavas from initial high silica rhyolite to final basaltic trachyandesite in the late pleistocene (~0.4 Ma). The …

The Origins of Four Paterae of Malea Planum, Mars
Malea Planum is a volcanic plain on the southern rim of Hellas Planitia, the largest impact basin on Mars. Four large circular structures on Malea Planum have traditionally been identified as paterae, or low relief, central vent volcanoes (Plescia and Saunders, 1979). A geologic map was constructed …

The geochemistry of the Atlanta Lobe of the Idaho Batholith in the western United States, Cordillera
… age province boundaries with the Wyoming and Snake River Plain Archaean provinces exist to the east and close to the southern margin of the Atlanta lobe. The Tertiary bimodal granitoids consist of a 55Ma-47Ma, metaluminous dioritic suite characterised by high Sr and Ba, low LILE and moderate …
