近年来，在华北板块北缘许多地区晚古生代地层中先后发现了多层火山事件沉积，而火山碎屑物质的物源区方向一直为地质界所关注。通过对辽宁西部南票矿区晚石炭世－ 早二叠世火山事件沉积与兴蒙槽区同期火山岩岩石化学及地球化学资料分析和研究，并采用多种判别图解进行了对比，令人信服地证明本区火山碎屑物质来自兴蒙槽区中酸性、钙碱性岛弧型火山喷发。这一研究结果对进一步探讨晚古生代火山喷发的古构造背景及火山事件沉积的时空展布规律具有重要的理论和实际意义。
In recent years, multi-layer volcanic events have been found in many Late Paleozoic strata in the northern margin of the North China Plate, while the source area of volcaniclastic matter has been of concern to the geological community. By analyzing and comparing the Late Carboniferous-Early Permian volcanic events and the petrochemical and geochemical data of volcanic rocks in the Xingmengang area in the Niaoqu area of western Liaoning Province and using various discriminant schemes, it is convincingly proved The pyroclastic materials in this area come from the acidic and calc-alkaline island arc volcanic eruptions in Xingmengang area. The results of this study have important theoretical and practical significance to further explore the Paleozoic volcanic eruptions in the paleotectonic background and the spatial and temporal distribution of volcanic events.
