a r t i c l e i n f o a b s t r a c t Keywords: spinel Moon Mg-suite plutonic lunar crust NASA's Moon Mineralogy Mapper (M 3) has identified and characterized a new lunar rock type termed pink spinel anorthosite (PSA) (Pieters et al., 2011). Dominated by anorthitic feldspar and rich in MgAl 2 O 4 spinel, PSA appears to have an unusually low modal abundance(More)
[1] New laboratory thermal infrared emissivity measurements of the plagioclase solid solution series over the 1700 $ 400 cm À1 (6–25 mm) spectral range are presented. Thermal infrared (TIR) spectral changes for fine-particulate samples (0–25 mm) are characterized for the first time under different laboratory environmental conditions: ambient(More)
The Piedmont region in the United States has been eroded and gullied due to deforestation and cultivation during the 1700 and 1800. Currently, a majority of these gullies are under forest vegetation and appear stable; however, neither the hydrology of these gullies, nor their sediment contribution to surface waters, has been quantified. This study(More)
