| Database dump for this sample: |
| Top depth (cm) | 101.0 |
| Bottom depth (cm) | 102.0 |
| Lithology | Muddy Diamict, low opal (5 percent), TOC content (<0.25 percent), and low water content (around 15-20 percent). Clasts include: quartz, dolerite, granite,metamorphic lithologies (foliated/mylontic granitoids, metasediments, biotite schists, marble). Highly fragmented diatoms (0.3 * 10^9 valves/g). |
| Facies interpretation | Subglacial transport and deposition in a subglacial or a grounding line proximal depositional setting (i.e. subglacial basal debris melt out). Lowest values of diatom and opal (but still high relative to other tills in antarctica, suggesting reworking of older diatom oozes), TOC and water content similar to other diamicts interpreted as tills elsewhere in the Ross Sea (Licht et al., 1996; Anderson, 1999; Domack et al., 1999, Mckay et al., 2008) and the Antarctic margin ((Smith et al., 2011)). |
