Figure F29. A, B. DEBI-pt scanning results for an aphyric variolitic basalt sample from whole-round Sample 336-U1383C-26R-1-MBIOA. Although mineral fluorescence (maroon) was detected throughout the sample, there were greater regions of organic fluorescence (yellow orange) compared to Sample 336-U1383C-6R-1-MBIOA (Fig. F28). The fluorescence from organics produced a large enough signal to obscure mineral fluorescence. Scale bar = 12 mm.
