Introduction: Northwest Africa 773 is one of the more unusual lunar meteorites found in recent years because it contains a prominent clast lithology, which appears to be an olivine-rich cumulate [1-4] and because it is a very-low-Ti (VLT) mare breccia with relatively high incompatible-trace-element concentrations and LREE/HREE enrichment [3]. A lunar origin was verified by Fagan and coworkers [...

We present lithology and fossil pollen data from a 384 cm sediment section from Qingtu paleolake in arid northwest China and discuss their environmental interpretations. The chronology was controlled by four accelerator mass spectrometry (AMS) radiocarbon dates on peat and bulk lake sediments. Lithology changes suggest a general sequence of local environment shifts from a non-lake environment b...

Terminal restriction fragment length polymorphism and 16S rRNA gene sequencing were used to explore the community composition of bacterial communities in biofilms on sediments (epipssamon) and rocks (epilithon) in stream reaches that drain watersheds with contrasting lithologies in the Noatak National Preserve, Alaska. Bacterial community composition varied primarily by stream habitat and secon...

The purpose of this study was to demonstrate the value of the proposed Hyperspectral Infrared Imager (HyspIRI) instrument for geological mapping applications. HyspIRI-like data were collected as part of the HyspIRI airborne campaign that covered large regions of California, USA, over multiple seasons. This work focused on a Southern California area, which encompasses Imperial Valley, the Salton...

Isotopic signatures of nitrogen, argon, and xenon have been determined in separated millimeter-sized pockets of shock-melted glass in a recently identified lithology of the meteorite Zagami, a shergottite. The ratio of nitrogen-15 to nitrogen-14, which is at least 282 per mil larger than the terrestrial value, the ratio of xenon-129 to xenon-132 = 2.40, and the argon isotopic abundances match t...

With increases in the mining depth and area Ordos coal field, failure law of super thick sandstone Zhidan group leads to frequent disasters, such as rock bursts mine earthquakes, which have become a significant issue, restricting large-scale continuous mining. To adequately understand movement mechanism super-thick weakly cemented overburden, promote resources under it, this study analyzes phys...

Differences in the impact of irrigation with freshwater versus wastewater on the underlying shallow groundwater quality were investigated in the Coastal Aquifer of Israel. Seven research boreholes were drilled to the top-most 3–5 m of the saturated zone (the water table region-WTR) in the agricultural fields. The unsaturated zone and the WTR below the irrigated fields consist mainly of clayey s...

The Jones Mountains (lat. 73°30’ S, long. 94° W) were discovered in January, 1960. In November of the same year, a University of Minnesota party led by Cam Craddock initiated studies of the geology of this previously unknown small group of mountains. The rocks exposed in this east-west trending group consist of a Mesozoic basement complex of granites in fault contact with younger felsic rocks. ...
