Abstract

Here, we present new results for the latter batch including micro-Raman spectroscopy to establish the mineralogy of the grains, and synchrotron radiation Xray tomographic microscopy (SRXTM) to precisely determine their volumes and masses. Furthermore we discuss an attempt to remove outer layers of extraterrestrial grains by Focused Ion Beam (FIB) technique, to minimize the interference of abundantly incorporated solar wind (SW, found within the uppermost 100s of nm of regolith grains) on the volumecorrelated cosmogenic noble gases. We also discuss the He and Ne content and CRE age of two newly studied grains from the first batch.
