根据对秦岭泥盆纪沉积盆地的构造成盆 -后期构造变形特征研究 ,秦岭造山带泥盆纪热水沉积成矿盆地中构造 -热流体地质事件可初步厘定如下 :1中泥盆世伸展构造成盆 -热水同生沉积成矿事件 (D1)。2晚泥盆世 -石炭纪伸展变形 -深源热流体叠加事件 (D2 )。3印支期挤压收缩变形 -热改造事件 (D3 )。 4燕山期逆冲推覆构造改造 -深源热流体叠加及脆性变形事件 (D4 )。 5喜玛拉雅山期脆性变形 (D5)。从盆地热状态及热演化研究角度看 ,盆地内充填地层体中有机质及矿物可以记录热状态及热演化历史 ,利用盆地内充填地层体中有机质及矿物温度计可以反演盆地内充填地层体形成时盆地热状态和盆地底部热流。认为热水沉积成矿盆地热状态及热演化主要研究方法有主要矿物流体包裹体测温、镜质体反射率 (R0 )法、氧同位素地质温度计法等。
Based on the tectonic basin-late tectonic deformation of the Devonian sedimentary basin in the Qinling Mountains, the geological events of the tectono-thermal fluid in the Devonian mineralization basin in the Qinling orogenic belt can be initially determined as follows: 1 Middle Devonian extensional structure Formation basin - hot water syngenetic sedimentary mineralization event (D1). Late Devonian - Carboniferous extensional deformation - superimposition of deep source thermal fluids (D2). 3 Indosinian extrusion shrinkage deformation - thermal reforming event (D3). 4 Yanshanian thrust nappe tectonic alteration - superposition of deep-hydrothermal fluid and brittle deformation event (D4). 5 Himalayan brittle deformation (D5). From the perspective of thermal state and thermal evolution in the basin, the organic matter and minerals in the filling formation in the basin can record the thermal state and thermal evolution history. Using the organic matter and mineral thermometers filled in the basin, the formation of the filling strata in the basin can be inverted Basin thermal status and basal heat flow. It is considered that the main research methods of thermal state and thermal evolution of hydrothermal sedimentary metallogenic basins include temperature measurement of main mineral fluid inclusions, vitrinite reflectance (R0) method and oxygen isotope geothermometer method.
