南华砷铊矿床位于云南省南华县城东南，北距县城55km。矿床产于上林罗统江边组雄黄厂段（Jc），以砷和铊元素组合为特征，属于典型的低温热液改造矿床。通过矿床地质、稀土元素和成矿模式的研究，对矿床成矿作用进行讨论。卤素，尤其氯是铊富集成矿的矿化剂，铊价态变化在富集成矿过程中具有重要作用。成矿流体是具有De和EU负异常的酸性溶液，基本保留了矿源层的稀土分布模式。在成矿过程中亲石元素和亲硫元素均不同程度地参与成矿作用。铊成矿期可分生物化学预富集期、构造活化成矿期和表生贫化期。
Nanhua arsenic thallium deposit is located in southeastern Nanhua County, Yunnan Province, Beiju county seat 55km. The ore deposit was produced in the Xiongmao Changxiong Xiongmai Plant Section (Jc), characterized by arsenic and thallium assemblages, belonging to a typical low-temperature hydrothermal alteration deposit. Through the study of ore deposit geology, rare earth elements and metallogenic model, the mineralization of the deposit is discussed. Halogen, especially chlorine, is a mineralizer for thallium-rich mineralization. The change of the valence state of the thallium plays an important role in the enrichment of mineralization. The ore-forming fluid is an acidic solution with De and EU negative anomalies, which basically retains the rare earth distribution pattern of the source bed. In the mineralization process, lithophile elements and pro-sulfur elements are involved in mineralization to varying degrees. Thallium mineralization period can be divided into biochemical pre-enrichment period, tectonic activation of mineralization and epigenetic degeneration.
