摘要
西祁连当金山清水沟一带的寒武纪火山岩发育在寒武纪拉配泉岩群火山岩组。对该火山岩分布特征和岩石学特征进行了研究,划分了3类火山岩岩相:爆发相、沉积相、喷溢相,并对火山岩喷发旋回进行了研究,揭示了当金山地区地层演化特征,对火山岩区域对比及火山机构恢复具有一定的指导意义。
Cambrian volcano rocks in Dangjinsha^-Qingshuigou area in western Qilian mountain developed in volcanorock group in Cambrian Lapeiquan group.Distribution characteristics ol the volcano rock and petrological characteristicshave been studied and divided into3types ol volcano rock lacies,such as eruption lacies,sedimentarylacies and effusive facies.Volcano eruption cycles have been studied as well.The formation evolution characteristicsin Dangjinshan area has been revealed.It has a certain guiding significance for the comparison ol volcanic rock areasand the recovery ol volcanic mechanism.
