松辽盆地周围沸石资源丰富 ,矿床类型多样 ,是中国东部环太平洋沸石成矿带的重要组成部分。研究区NE—NNE向深大断裂带控制着中生代火山岩和沸石矿带的空间展布 ,而不同方向深大断裂带的交接复合地段则决定了沸石矿田和主要矿床的空间定位。燕山中晚期以挤压-剪切 (左行 )为主的构造动力学机制控制了富碱高钾火山岩的发育 ,为沸石矿源岩的形成期 ;喜山期的构造反转以拉张 -剪切 (右行 )为主的构造动力学机制及其相伴的岩浆热事件 ,导致区域地热异常、地下流体增温和沸石矿化作用的快速进行。研究区中生代火山岩系中沸石矿床的主成矿期为喜山期 (6 4 5~ 5 5 0Ma)。
The zeolites around the Songliao Basin are abundant in resources and diverse in deposit types. They are an important part of the Pacific Rim metallogenic belt in the eastern part of China. The NE-NNE in the study area controlled the spatial distribution of the Mesozoic volcanic rocks and zeolite ore belts to the deep fault zone, while the transitional complex zones in the deep and deep faults in different directions determined the spatial location of the zeolite orefield and the major ore deposits. The tectonic dynamics dominated by extrusion-shear (left line) in late Yanshanian controlled the development of alkali-rich high-k volcanic rocks, forming the source rock of zeolite. The structural inversion in the Himalayan period was controlled by tension-shear The tectono-dynamic mechanism dominated by cutting (right line) and its accompanying magmatic thermal events led to rapid regional geothermal anomalies, warming of underground fluids and zeolite mineralization. The main mineralization stage of the Mesozoic volcanic rocks in the study area is the Himalayan period (64.5-550 Ma).
