通过对喀拉通克矿区1号和2号岩体中铜镍硫化物矿石的Re_Os同位素测年,获得两个等时线年龄数据分别为282.5±4.8Ma和290.2±6.9Ma,187Os/188Os初始比值分别为0.2563±0.0037和0.2721±0.0053,γOs值分别为202.23～1061.59和195.07～473.24,平均值分别为495.05和289.83。上述结果表明成岩成矿年龄极为接近,均介于石炭纪末至早二叠世之间,并且在成矿和岩浆侵位过程中有大量地壳物质混入成岩成矿系统。喀拉通克镁铁质超镁铁质岩带形成于后碰撞的伸展构造环境。
Based on the Re_Os isotope dating of copper-nickel sulfide ores in rock masses No.1 and No.2 of Kalatongkang, the two isochron age data were obtained as 282.5 ± 4.8Ma and 290.2 ± 6.9Ma respectively, and the initial values of 187Os / 188Os The ratios were 0.2563 ± 0.0037 and 0.2721 ± 0.0053, respectively. The values of γOs were 202.23 ~ 1061.59 and 195.07 ~ 473.24, with the average values of 495.05 and 289.83, respectively. The above results indicate that the age of diagenetic mineralization is very close, ranging from the end of Carboniferous to the Early Permian, and a large number of crustal materials are mixed into the diagenetic mineralization system during mineralization and magmatic emplacement. Kalatongke mafic ultramafic belt was formed in the post-collision extensional tectonic setting.
