摘要：

松辽盆地北部深层下白垩统的砂岩为成分成熟度很低的岩屑长石砂岩及长石岩屑砂岩。主要成岩作用有:自生粘土边、石英长石次生加大、斜长石的钠长石化、自生浊沸石,以及次生长石和浊沸石溶蚀等。斜长石的钠长石化作用是浊沸石析出的主要机制,而粘土矿物的转化则为浊沸石的沉淀提供了钠和硅的来源。

Abstract:

Deep buried sandstones of Lower Cretaceous in North Songliao Basin are compositionally immature lithic arkose and feldspathic litharenite. The main diagenesis of the sandstones includes:authigenetic clay rim, quartz and feldspar overgrowth, albitization,authigenetic laumontite and the dissolution of feldspar and laumontite. The albitization of anorthosite is the primary mechanism for generating laumontite, whereas the transformation of clay minerals provides sodium and silicon for the precipitation of laumontite.
