都匀牛场早泥盆世暗河沉积,是我们1980年作古油藏综合研究时发现的。两年来对暗河沉积、暗河沉积的成岩、暗河砾石成砾以前的成岩,暗河沉积中的油气等等的研究,不同程度上加深了区域地质的某些认识,这对于探讨古油藏石油的生成、储集、再聚集、保存,以及其它领域中的一些问题都有直接或间接的作用。这里只谈暗河沉积的成岩系列,以及尚属首次发现的交代陆源碎屑形成的淡水白云石。 The Duyun deposit of the Early Devonian in Duyun Cattle was discovered during the comprehensive study of the ancient reservoirs in 1980. The research on the sedimentation of the under-river, the sedimentation of the under-river, the diagenesis before the gravel pebbles of the under-river gravel, the oil-gas in the sediments of the under-river and so on in the past two years have deepened some understanding of the regional geology in varying degrees. Tibetan oil generation, storage, re-aggregation, preservation, and some other areas have a direct or indirect role. Here only to talk about the sedimentary series of sedimentary rocks, as well as for the first time found to confront the formation of freshwater dolomite debris.
