近年来,西泰岭北带中泥盆世地层中发现了大型和超大型微细浸染型金矿而成为热点地区,其中古地理环境则是沉积学者关注的重要研究课题。当前有两种截然不同的观点:(1)认为中泥盆世为浅海陆架至潮坪环境;(2)为半深海-深海的海底峡谷-水道-浊积扇体系。近期笔者对该组进行了详细的研究,得出与前两种观点不尽相同的认识。 In recent years, large and extra-large finely disseminated gold deposits have been found in the Middle Devonian strata in the northwestern part of the Xitian Mountains, becoming a hot area. Among them, the paleogeographic environment is an important research subject of sedimentary scholars’ attention. There are currently two distinct perspectives: (1) that the Middle Devonian is a shallow shelf-tidal flat environment; and (2) a semi-deep sea-deep sea submarine canyon-water-turbidite fan system. Recently I conducted a detailed study of the group, reached with the first two views of different understanding.
