Database dump for this sample:
Top depth (cm) 79.0
Bottom depth (cm) 80.0
Lithology Weakly-stratified muddy diamict with common granule-sized intraclasts of mud and diamict. TOC (0.27- 0.37 percent), low water content (25-30 percent). Clasts include: quartz, dolerite, granite,metamorphic lithologies (foliated/mylontic granitoids, metasediment, biotite schists, marble). Highly fragmented diatoms (0.4 * 10^9 valves/g).
Facies interpretation Glacimarine sediment deposited proximal to grounding line by melt out of subglacial basal debris. A lower sand content than Facies Dm suggest some water sorting during deposition, while the slightly elevated diatom abundance, water content and TOC compared to the underlying massive diamict suggest an increasing marine influence. (Domack et al., 1999). Common intraclasts are consistent with the granulated facies of Domack et al., 1999.
