the nayband strike-slip fault forms the western margin of the micro-continental lut block in eastern iran. neogene and quaternary mafic volcanic rocks collected near tabas, along the northern part of the fault (nnf; 15 ma), and further to the south, along the middle part of the fault (mnf; 2 ma), are within-plate sodic-series alkali olivine basalts with high tio2 and up to >16% normative nephel...

The National Aeronautics and Space Administration (NASA)’s Operation IceBridge (OIB) was a 13-year (2009–2021) airborne mission to survey land sea ice across the Arctic, Antarctic, Alaska. Here, we review OIB’s goals, instruments, campaigns, key scientific results, implications for future investigations of cryosphere. primary goal use laser altimetry bridge gap in fine-resolution elevation meas...

Late Jurassic NE-trending A-type granitoids are widespread in the Shihang belt, South China, though their petrogenesis and geodynamic settings remain controversial. The Guiping complex is located on southwest margin of belt. In this study, petrography, major trace element geochemistry, whole-rock Sr-Nd isotopes, zircon U-Pb geochronology were investigated. composed Fenghuangling Xishan plutons;...

Abstract. Antarctic digital elevation models (DEMs) are essential for fieldwork, ice motion tracking and the numerical modelling of sheet. In past 30 years, several DEMs derived from satellite data have been published. However, these either coarse spatial resolution or aggregate observations spanning which limit their further scientific applications. this study, new generation laser altimeter I...

The Basalt of Summit Creek is an enigmatic basalt unit that is about 55 million years (Ma) in age, located south of Mount Rainier. These basalts formed in a transitional time between the formation of the Coastal Range Basalts and the present Cascade arc. Through geochemical and paleomagnetic techniques, samples were collected and analyzed. Paleomagnetic samples showed nearly complete post erupt...

The Nayband strike-slip fault forms the western margin of the micro-continental Lut block in Eastern Iran. Neogene and Quaternary mafic volcanic rocks collected near Tabas, along the northern part of the fault (NNF; 15 Ma), and further to the south, along the middle part of the fault (MNF; 2 Ma), are within-plate sodic-series alkali olivine basalts with high TiO2 and up to >16% normative nephel...

The Multi-Channel Coherent Radar D e p t h S o u n d e r (MCoRDS) system was developed by the Center for Remote Sensing of Ice Sheets (CReSIS) at the University of Kansas to map the thickness and underlying bed elevation for glaciers in Antarctica on the NASA Operation Ice Bridge (OIB) mission. Scientists believe that the lubricating effect of liquid water at the bed-ice interface will signific...
