东天山康古儿韧性剪切带分布有众多镁铁质-超镁铁质岩体,这些岩体在形成的空间和时间上都具有密切的联系。通过对该成矿带典型矿床岩石氧化物做变异图解,具有较好的线性关系。典型矿床的稀土元素也具有相似的特点。含矿岩体具有高镁、低碱、低钙、低铝、低钛和较高的Mg′特征,显示出深源岩浆充分分异的特征。根据TiO2/10-P2O5-MnO图判别出本区岩浆具有拉斑玄武岩到钙碱玄武岩过渡的性质,岩浆源具有钙碱性玄武岩浆特征。含矿性较好的的原岩具有高m/f值、高S和低Ni/Co值的特征。
There are many mafic-ultramafic rocks distributed in the Kangute children ductile shear zone in the East Tianshan Mountains. These rock masses are closely related in the space and time of formation. Through the variation diagram of rock oxide in the typical ore deposit, it has a good linear relationship. The rare earth elements of typical deposits also have similar characteristics. The ore-bearing rock mass is characterized by high Mg, low alkali, low Ca, low Al, low Ti and high Mg ’, which shows that the deep source magma is well-differentiated. According to the TiO2 / 10-P2O5-MnO map, the magma in the area is characterized by the transition from tholeiitic basalt to calcareous-basalt. The magmatic source has the characteristics of calc-alkaline basaltic magma. The protoliths with better oreability have the characteristics of high m / f value, high S and low Ni / Co value.
