| 摘 要： | 对大港探区下第三系砂岩和碳酸盐岩中胶结物和填隙物期次特征、来源、形成机理以及形成时代进行了地球化学研究。结果表明，石英次生加大边的硅质来自粘土矿物的转化、长石的溶解和热对流作用；寒武纪灰岩中的方解石脉来源于沉积时期的原生水的沉积，奥陶纪砂屑灰岩的胶结物来源于大气水成因，从而为有关古流体和古温压特征以及油气运聚规律的研究提供了重要的地球化学资料。

| Abstract: | Geochemistry study on the forming mechanism of the cement of sandstone and carbonate from Dagang exploration area was carried out in this paper The study results showed that the silicon in quartz overgrowth did not come from the pressure dissolution of the quartz grain,but from the transformation of the clay mineral,the dissolution of foldspar and the convection of heat The calcite veins in Cambrian period limestones formed through the diffusion of under ground water,the calcite veins in Ordovician period limestones formed mainly through the precipitation of atmosphere water The forming time of the overgrowth of quartz grain was also given,which provided a very important basis for the study on the paleo fluid and paleo temperature and pressure |
