The presence of medium-grade organic matter confirmed by Raman spectroscopy is reported for the first time from the Zor diamictite of the Ramsu Formation, Tethyan Himalaya. The organic matter has undergone overmature thermal evolution. The sediment shows low total organic carbon (TOC) and low total sulfur (TS) values of <0.25% and <0.01%, respectively. Low TS/TOC < 0.08 suggests oxic bottom waters during the deposition of the Zor diamictite. The recovered palynomorph assemblage includes Leiosphaeridia spp., Kildinosphaera verrucata, Trachyhystrichosphaera sp., the filamentous cyanophyte Taeniatum sp., the clusters of simple, spheroidal forms Myxococcoides sp., and the colonial cyanobacteria Synsphaeridium sp. This palynomorph assemblage suggests a Neoproterozoic age for the Zor diamictite of the Ramsu Formation.

从印度查谟和克什米尔兰班地区拉姆苏组新元古代 Zor 混叠岩中发现有机质和孢粉体

首次报道了特提斯喜马拉雅山 Ramsu 组的 Zor 混叠岩中存在经拉曼光谱证实的中等有机质。有机物经历了过成熟的热演化。沉积物显示出低总有机碳 (TOC) 和低总硫 (TS) 值，分别为 <0.25% 和 <0.01%。低 TS/TOC < 0.08 表明在 Zor 混叠岩沉积期间底水含氧量高。回收的孢粉组合包括 Leiosphaeridia spp.、Kildinosphaera verrucata、Trachyhystrichosphaera sp.、丝状蓝藻 Taeniatum sp.、简单的球状形式 Myxococcoides sp. 和殖民地蓝藻 Synsphaeridium sp.。这种孢粉体组合表明拉姆苏组的佐尔混叠岩属于新元古代。
