碳酸盐沉积物的胶结成岩环境一般与沉积环境是一致的,但也可不一致,如海面以下的沉积物可抬升至海水面以上成岩。各种胶结成岩环境的胶结物特征是不相同的,据此可判别各沉积成岩环境,区分深海、浅海、潮下带、潮间带、萨布哈、礁、滩等沉积环境,也可鉴别大气淡水渗流带、潜流带和埋藏成岩环境。大气淡水成岩的胶结物类型主要有触点-新月型、重力、渗滤砂、共轴生长边、淡水粒状亮晶等,并伴有大量溶孔等,有利于油气及某些金属矿产的储集。
The carbonate diagenetic environment of carbonate sediments is generally consistent with the sedimentary environment, but it may also be inconsistent. For example, sediments below sea level can be uplifted to diagenesis above sea level. Various cementing diagenetic environments have different cementation characteristics, so that diagenetic environments can be distinguished from each other to distinguish sedimentary environments of deep sea, shallow sea, subtidal zone, intertidal zone, Sabuha, reef and beach, Atmospheric freshwater seepage zone, subsurface flow zone and buried diagenetic environment. Atmospheric freshwater diagenetic cements are mainly contact - crescent type, gravity, percolation sand, co-growth edge, freshwater granular spangle, etc., accompanied by a large number of dissolved pores, is conducive to hydrocarbons and some metal minerals Storage.
