| 摘 要： | 结合前人研究成果和本次勘探工作,分析了大四家子区沸石矿床矿体特征、矿石类型及矿物成分、矿石的化学成分、矿石的物理化学性能等,认为沸石矿由火山喷发的酸性碎屑岩和熔岩中的玻璃质,在火山活动晚期的热气液作用下脱玻而成,属于火山热水溶液型沸石矿床,提出了中生代断陷盆地内下白垩统义县组酸性火山熔岩和碎屑岩发育地带,特别是沸石岩、珍珠岩出露地带是下一步寻找沸石矿的有利地区,圈定了3个找矿远景区和2个找矿靶区。

| Abstract: | According to the previous research results and this exploration work,the characteristics of ore body,ore type and mineral composition,chemical composition and physical and chemical properties of ore in Dasijiazi area are analyzed.It is believed that the zeolite ore was formed by the devitrification of the acid clastic rocks and lava from the volcanic eruption under the action of gas-bearing hydrotherm in the late volcanic activity and belong to the volcanic hydrothermal solution zeolite deposit.It is suggested that the areas of acid volcanic lava and clastic rocks in the lower Cretaceous Yixian Formation of the Mesozoic graben basin,especially the exposed areas of zeolite and pearlite,are the favorable areas for further exploration of zeolite deposits,three prospecting areas and two prospecting targets are delineated. |
