摘 要: 古岩溶及其成矿作用的研究是鄂东南多金属成矿带沉积学和矿床学工作的较薄弱环节之一。作者依据大量野外观测资料,提出识别该区古岩溶岩系的地层、构造、形态和岩石学等四种标志及其古岩溶岩系的成因分类方案,对古岩溶在时间、空间上发育之强度、多期性及其优先发育部位亦作了分析,并阐述岩浆活动对该区古岩溶发育的影响。最后对古岩溶岩系的生成环境,形成作用和时间进行初步探讨。 The research on paleokarst and its minerogenetic role in the south-eastern Hubei ore belt is still weak up to now. Some stratigraphic structural, morphological and petrologic criteria can be used to judge paleokarst system in Southeastern Hubei based on field observation. The paleokarst system can be classified into six types of rocks. The intensity, the multistage in time and the prefe rence in space as well as the influence of magmatism in the process of developping palaeokarst are analysed in this paper. Besides,the sedimentary environment, the time and process of the genesis of the paleokarst system are also discussed.
