Types and Succession of Pyroclastic Rocks Diagenesis in Lower Cretaceous of Wuerxun and Bei'er Depression in Hailaer Basin
-
摘要: 海拉尔盆地乌尔逊-贝尔凹陷下白垩统发育火山熔岩-正常碎屑沉积岩之间的过渡岩石类型，其成岩作用类型与正常沉积岩相比具有特殊性.采用显微镜下描述与扫描电镜分析相结合的方法对研究区成岩作用类型进行了研究，并总结出成岩作用序列.结果显示火山碎屑岩的成岩作用类型包括熔结作用、机械渗滤作用、压实作用、脱玻化作用、重结晶作用、胶结作用、自生矿物转化和溶蚀溶解作用.其中，熔结作用、脱玻化作用以及凝灰质的溶蚀溶解作用是火山碎屑岩所特有的成岩作用类型.研究区具有成因联系的成岩共生组合主要有4类，分别是：(1)微晶石英和微晶方解石；(2)石英的溶解与结晶；(3)自生白云母、蒙皂石、伊利石和绿泥石；(4)沸石与自生长石.成岩序列可以分为熔结作用阶段、机械渗滤作用阶段、脱玻化作用阶段、凝灰质溶蚀溶解作用阶段、粘土矿物混层阶段、自生白云母阶段、沸石胶结阶段、颗粒强烈胶结阶段以及铁白云发育阶段.研究区下白垩统处于早成岩B期至晚成岩B期，主要为晚成岩A期.Abstract: A set of rocks between volcanic lava and normal sedimentary clastic rock were developed in Lower Cretaceous of Wuerxun and Bei'er depression in Hailaer basin. Compared with normal sedimentary rocks, their diagenesis types are particular. The methods of description of microscopic sections and scanning electron microscope (sem) are used to research the diagenesis types, and to summarize succession of diagenesis. The results show that types of pyroclastic rocks diagenesis include weldition, mechanical percolation, compaction, devitrification, recrystallization, cementation, transformation of neogenic mineral and dissolution. Weldition, devitrification and dissolution of tuffaceous matter are specific diagenesis types in pyroclastic rocks. There are four typical diagenetic paragenetic associations which have genetic relationships, including (1) microcrystalline quartz and microcrystalline calcite; (2) quartz dissolution and crystallization; (3) authigenic muscovite; smectite; illite and chlorite; (4) zeolite and authigenic feldspar. The order succession of diagenesis is as follows: weldition, mechanical percolation, devitrification, dissolution of tuffaceous matter, claymineral mixed layer, authigenic muscovite, zeolite cementation, particles strong cementation and ankerite. The diagenesis stage of Wuerxun in Lower Cretaceous ranges from early diagenetic B to late diagenetic B. The main stage is late diagenetic A.
