摘要
湖北南漳中三叠统巴东组是一套碳酸盐与陆源碎屑混合沉积,属低能的潮坪-泻湖环境。表现为下列七种形式:(1)碎屑岩与灰岩互层,(2)碎屑岩夹灰岩,(3)灰岩夹碎屑岩,(4)碳酸盐在碎屑岩中呈胶结物,(5)陆源碎屑散布于碳酸盐基质中,(6)陆源粉砂充填于砾屑灰岩的砾屑之间,(7)碳酸盐颗粒散布于陆源泥中。
The Middle Triassic Badong Formation,situated in Nanzhang,Hubei Province,isa set of mixed carbonate-terrigenous clastic sediments deposited mainly in a low energytidal flat-lagoon environment.The sediments occurred in following seven types:1.lime-stone-clastic rocks interbeds;2.clastic rocks intercalated with limestons;3.limestonesintercalated with clastic rocks;(?).carbonate appeared as cement in clastic rocks;5.terri-genous clastics distributed in carbonate matrix;6.terrigenous silts filled in pores of intra-clastic limestone;7.carbonate intraclasts distributed in terrigenous mud.
