摘要
羌塘地区是青藏高原最大的一块中比例尺地质调查空白区,许多关键地质问题集中于此。综合多年羌塘地区的地质实践,结合近年来1∶25万地质调查的初步成果,提出龙木错-双湖板块缝合带、蛇绿岩、高压变质带、羌塘的基底、南北羌塘地层序列及地层格架、盆地成因类型、羌塘盆地与油气资源、羌塘地区的深部地质结构、羌塘地区生态与环境等方面存在的问题,期望起到抛砖引玉的作用,提供给在羌塘地区从事地质调查的同行们参考。
The Qiangtang area is the largest geological blank in medium-scale geological survey of the Qinghai-Tibet plateau, at which many geological problems center. On the basis of many years of geological practice in the area, combined with primary results obtained in the recent 1∶250000 geological investigation, the authors put forward a series of geological problems about the Lungmu Co-Shuanghu Lake Paleo-Tethys plate suture, ophiolites, high-pressure metamorphic belt, basement in Qiangtang, stratigraphic successions and frameworks in southern and northern Qiangtang, genetic type of the Qiangtang basin, Qiangtang basin and its oil-gas resources, deep geological structure in the Qiangtang area, ecology and environment of the Qiangtang area and so on. We hope that these problems can catch people′s attention and be used for reference for colleagues engaged in geological investigation in the Qiangtang area.
