WebAbstract. Many planetary surfaces have been shaped by eolian and fluvial processes, and understanding the resulting landscape is of critical importance to understanding changes in climate. Surface features on Earth and Mars are commonly observed using a variety of remote sensing methods.

WebThree quartzo-feldspathic gneiss samples were chosen for detailed SIMS analysis in this study. Samples were collected from extensional gneiss domes [ Hill , 1994 ; Little et al ., 2007, 2011 ] in the D'Entrecasteaux Islands, southeastern PNG (Figure 1 ), which occur in a zone of active extension (i.e., Woodlark Rift) at the western apex of the Woodlark Basin.
