摘要(Abstract):

松辽盆地下白垩统下部地层中所发现的浊沸石,产于由长石、石英及酸性喷发岩岩屑所组成的混杂砂岩之中,呈胶结物形式,是一种典型的自生矿物,其埋藏深度多在3000米以上。它的出现,在勘探初期,对于粗略评价生储层,研究其纵向演变规律,具有重要的地质意义。
: The laumontite found at the lower part of the strata of lower Cretaceous in Songliao Basin came from apogrile which consists of feldspar, quartz, and acidic effusive rock cuttings. It is a typical autoyenetic mineral presenting as a matrix and buried at a depth less than 3000m. Its occurrence has important geological significance for grossly evaluating source rocks and reservoirs and for revealing their vertical evolution laws during the early stage of exploration.
