摘　　要：在松辽盆地深层发育的中生代酸性火山岩中首次发现氟碳钙铈矿。氟碳钙铈矿的寄主岩为球粒流纹岩、流纹岩、流纹质熔结凝灰岩、流纹质凝灰岩，其寄主岩分布深度为2930～3830m，形成时代为早自垩世晚期。氟碳钙铈矿常与石英、碳酸盐、钠铁闪石、钠长石、绿泥石、绿帘石、粘土矿物等次生矿物共生，并与天然气储层有着一种内在的联系。氟碳钙铈矿是岩浆后期热液和大气降水多阶段、多次作用萃取的产物，这种相互作用是多元体系参与并经历了多阶段演化，氟碳钙铈矿形成于富Ca^2＋和CO2^3-的流体及还原环境。松辽盆地周边地区广泛发育的中生代火山岩与松辽盆地深层中生代火山岩十分相似，松辽盆地周边地区是否存在一个巨大的氟碳钙铈矿潜在资源，值得注意。In Songliao basin occur Mesozoic basic, intermediate and acidic volcanic rocks and parasite is first discovered in the acidic volcanic rock. Parisite is hosted in the granular rhyolite, rhyolite and rhyolitic ignimbrite. The host rocks were formed in Late Early Cretaceous Epoch buried to depth of 2 930-3 824m. Parisite is associated with secondary minerals, such as quartz, carbonate minerals, arfvedsonite, albite, chlorite, epidote and clay minerals and has intrinsic relation with reservoir. It is resulted from multi-stage and multi-times extraction from late magmatic hydrothermal fluid and meteoric water that is rich in Ca^2＋ and CO2^2- under reduced environment. Characteristics of extensive Mesozoic volcanic rocks in surrounding areas of the basin are quite similar to that the volcanic rocks buried in the basin thus attention should be paid to parasite mineral resources in the surrounding volcanic rocks.
