【摘要】 在大量文献调研的基础上,探讨了云南省页岩发育的地质背景,总结了页岩形成时代和特点,明确了勘探开发的目标层位,研究了潜质页岩的形成环境和分布规律.结果表明,下寒武统筇竹寺组、下志留统龙马溪组、上志留统玉龙寺组和上三叠统须家河组可作为勘探开发的重点层位.筇竹寺组潜质页岩主要形成于陆棚环境,主要分布在滇西保山地区、滇中北部、滇东、滇东北和滇东南广大地区;由于大规模海退,龙马溪组潜质页岩仅分布在滇西保山地区、滇中北部和滇东北北部地区;因为滇东及滇东北地区继续发生大面积海退,玉龙寺组潜质页岩局限于曲靖、马龙、昆明、澄江一线;须家河组潜质页岩形成于陆相环境,主要分布于滇中分区和滇西兰坪-思茅地区.更多还原

【Abstract】 The geological background,forming ages and characteristics,target strata,forming environment and distribution regularity of shales in Yunnan Province are studied on the basis of a large number of literatures. The results show that the exploration should focus on the Lower Cambrian Qiongzhusi Formation,Lower Silurian Longmaxi Formation, Upper Silurian Yulongsi Formation and Upper Triassic Xujiahe Formation. The potential shales of Qiongzhusi Formation formed in the continental shelf environment are mainly distributed in western,north central,eastern,northeastern and southeastern Yunnan,while those of Longmaxi Formation are only occurred in western,north central and northeastern areas due to large-scale regression. With the continuous large-area regression in the east and northeast,the potential shales of Yulongsi Formation are confined to Qujing-Malong-Kunming-Chengjiang areas,and those of Xujiahe Formation formed in continental environment mainly in the central subarea and Lanping-Simao area.更多还原
