对富金钠长石岩的岩石化学、微量元素及稀土元素分析显示，大沟谷钠长石岩与区域上震旦系乐昌峡群片岩及附近花岗岩没有成因联系．富金钠长石岩主要是热水沉积形成的．钠长石岩与金矿有紧密的内在联系，钠长石岩型金矿床是热水沉积＋改造作用形成的
The petrochemical, trace element and rare earth element analysis of the gold-bearing albite shows that there is no genetic relationship between the large-gable albite and the Upper Sinian Lechangxia Group schists and the adjacent granites. Gold-rich albite is mainly formed by hydrothermal sedimentation. Albite and gold deposits are closely linked, and albite rocks are formed by hydrothermal sedimentation + remodeling
