秦岭-大别造山带中、新生代中酸性火山岩的地球化学研究表明,该区中酸性火山岩是由幔源基性岩浆与壳源物质的混合物经过多种过程(部分熔融、分离结晶等)综合作用形成的。结合野外地质产状和同位素热年代学资料,作者认为研究区中、新生代火山岩产出于拉张的构造环境中。
Geochemical studies of Mesozoic and Mesozoic mid-acidic volcanic rocks in the Qinling-Dabie orogenic belt show that the intermediate-acid volcanic rocks in the area are synthesized by a combination of mantle-derived basic magma and crustaceous material (partial melting, separation and crystallization, etc.) The role of formation. Combined with the geology and isotope geochronology data, the author believes that the Mesozoic and Cenozoic volcanic rocks in the study area are in the extended tectonic setting.
