Himalayan uplift impacts on methane flares

为了研究海洋天然气水合物储集系统，对孟加拉湾沉积物进行了元素、正构烷烃、稳定碳（δ 13 C）和氮（δ 15 Ntot）同位素组成的测定。TOC，C/N比和同位素组成的研究沉积物表明，海洋和陆源有机质的混合物。负的δ 13 C值也表明微生物甲烷占优势的天然气水合物沉积。沉积物的积累速率和TOC可能控制高地壳物质输入响应喜马拉雅山脉的隆升。

Sediments from the Bay of Bengal were measured for elemental, n-alkanes, and stable carbon (δ13C) and nitrogen (δ15Ntot) isotopic compositions to examine the gas hydrate reservoir systems in the oceanic region. The TOC, C/N ratio and isotopic compositions of the studied sediments suggest a mixture of marine and terrestrial derived organic matter. The negative δ13C values also indicate gas hydrate deposits of microbial methane dominant. Sediment accumulation rate and TOC are likely controlled by high crustal materials input in response to uplift of the Himalaya.
