Rb—Sr法地质年代学研究表明,莲花山钨矿区内的花崗岩和酸性火山岩是同时形成的。其等时线年龄分别为:137.2±2.5百万年,(Sr初始值(Sr~(87)/Sr~(86))_0=0.70696±0.00056);135.8±7.3百万年,(Sr初始值(Sr~(87)/Sr~(86))_0=0.70613±0.00035)。成矿时代接近成岩时代。
Rb-Sr geochronology studies show that the Lianhuashan tungsten ore district and acidic volcanic rocks are formed at the same time. The isochrons ages were: 137.2 ± 2.5 million years (Sr ~ (87) / Sr ~ (86)) _0 = 0.70696 ± 0.00056); 135.8 ± 7.3 million years (Sr initial value (Sr ~ (87) / Sr ~ (86)) _0 = 0.70613 ± 0.00035). The mineralization age is close to the diagenetic age.
