摘　　要：中—低温热液型拖布卡金矿,与碱性(钠质)岩浆作用密切相关,尤以与纳长斑岩、二长斑岩最为明显。三类矿源岩石组合提供金质。自然金、显微裂隙金及包裹金组成金的主要赋存状态。提出拖布卡—播卡金矿成矿模式。The Tuobuka Au deposit of middle-low T hydrothermal type has a close relationship with the alkaline （sodic） magmatism, which especially has an evident relation to the albite porphyry and monzonite porphyry. The Au is originated from 3 rock assemblages. The main occurrence states of Au are the native Au, the microfissure Au and the inclusion Au. And the metallogenetic model of Tuobuka - Boka Au deposit is put forward finally in this paper.
