| Text Description: | Luna pyroclastic deposits. A bag of hand-picked pumices from the young pfs that formed south shore bluff prior to 2008. These from about 1 m below 08 vegitation surface. Individual pumices present as two major groups. (a)Vesicular dark to light olive gray w/ orange-red oxidation and light olive gray rinds, glass threads and fibers in gms, very vesicular. (b) Denser med-olive-gray w/ finer vesicles and lacking obviously stretched glass fibers. Would have thought these were separate lithologies but pMax in bag (13x8x6.5 cm) has a core of (b) grading irregularly to (a) --- not obvious banding- may be diffuse banding. So (a) and (b) may be core vs rim, yet the same material - samples taken of each, just in case. These two lithologies similar to those in wes006. Chemistry sample of 009a is from pMax. 009b is two smaller pumices together. |
