陕西金堆城斑岩钼矿床是中国最大的钼矿床之一，按照脉体相互切割关系，成矿过程可分为两期十个阶段。矿区内流体包裹体研究表明：成矿流体以富ＣＯ２为特征，温度介于８３℃～４１２℃之间，盐度介于２７５～４２５ｗｔ％ＮａＣｌ和０６１～１７ｗｔ％ＮａＣｌ两个区间内，具有典型的双配分模式特征。氢、氧同位素资料研究表明成矿物质主要来自岩浆流体。晚阶段有大量雨水混入热液流体中，导致流体的温度、盐度和δ１８ＯＨ２Ｏ、δＤ值降低，引起了成矿流体中的钼金属沉淀，形成了金堆城超大型斑岩钼矿床。
The Jinduicheng porphyry molybdenum deposit in Shaanxi Province is one of the largest molybdenum deposits in China. According to the relationship between veins and cutting, the mineralization process can be divided into two stages of ten stages. The study of fluid inclusions in the mining area shows that the ore-forming fluid is characterized by rich CO2, the temperature is between 83 ℃ and 412 ℃, the salinity between 275 ~ 425wt% NaCl and 061 ~ 17wt% NaCl Within a range, with a typical dual-mode features. Hydrogen and oxygen isotope data indicate that ore-forming materials are mainly derived from magmatic fluids. In the late stage, a large amount of rainwater is mixed into the hydrothermal fluid, causing the temperature, salinity and δ18OH2O, δD values of the fluid to decrease, causing the molybdenum metal precipitation in the ore-forming fluid and forming the Jinduicheng ultra-large porphyry molybdenum deposit.
