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...

Beside the complexities and not readily practical applications resulting from full Zoeppritz equation, seismic amplitude reflection does give enough information beyond critical angle. Consequently, there are breakdown of equation approximations at angle incidence (Shuey’s approximation). More so, validity is only for slight contrast in elastic parameters across formations small assumed. In an a...

Reflection amplitude as a function of offset is effective in characterizing lithology in oil producing basins. Experience shows that AVO inversion methods based on amplitude-preserved prestack migration typically provides a more accurate lithology estimation than NMO-based AVO analysis. However, some artifacts may be introduced into the migration section, which can obscure the estimate of reser...

Introduction: Tagish Lake, an observed fall in the year 2000, was classified by [1] as a type 2 carbonaceous chondrite. It bears similarity to CI 1 and CM chondrites but is distinct from both. [2] noted that the overall trace elements abundance pattern in Tagish Lake is similar to those of CM chondrites indicating that Tagish Lake and CMs experienced very similar nebular processes. The mineralo...

The “Danxia landform” is an erosional landform type originally defined in China. It is characterized by redcolored sandstones and steep cliffs, and developed via long-term erosion. Detailed quantitative geomorphometric studies of the characteristics of Danxia landforms in China have not yet been conducted. Using GIS, we conducted DEM-based geomorphometric analyses of 42 watersheds on Mt. Danxia...

Assessing the impact of glaciations on topography and co-evolution ice-sheet dynamics requires a thorough understanding factors that control fjord morphology. We investigate role lithology glacial valley form using topographic analyses numerical landscape evolution models. measure depths widths from East Central Greenland (68°N–75°N), find width, with wider fjords in softer rocks (i.e., sedimen...
