Methyltrimethyltridecylchromans (MTTCs) are structurally similar to tocopherols, which were identified in large numbers of source rocks and crude oils (Pleistocene to Early Cambrian). The occurrence of MTTCs was widely used as a proxy indicator of paleosalinity in the field of organic geochemistry. However, their origin and geological formation pathway still remain greatly debated. Here, we review the progress made over the past 30 years in the distribution and origin of MTTCs and their applications. Furthermore, we discussed several key points for future studies on MTTCs.
甲基三甲基十三烷基色满(MTTCs)在结构上与生育酚相似,在大量源岩和原油(更新世至早寒武世)中被发现。在有机地球化学领域,MTTCs的存在被广泛用作古盐度的替代指标。然而,它们的起源和地质形成途径仍存在很大争议。在此,我们综述了过去30年里在MTTCs的分布、起源及其应用方面取得的进展。此外,我们还讨论了MTTCs未来研究的几个关键点。
