Finally, it can be concluded for the first time that there was a large time gap between diagentic process of the volcanic rocks related to the Dapingzhang VHMS deposit and the ore-forming process, then a ore-forming model of the Dapingzhang deposit can be made, that is, the deposit passed through two important stages: the ore-forming metals concentrated during formation of the Early Palaeozoic spilite-quartz keratophyre on the island-arc belt, and the mineralization caused by the Late Palaeozoic magmation.

最后，首次提出与块状硫化物矿床有关的火山岩成岩过程和成矿过程可以有较大的时间间隔。在此基础上建立了大平掌矿床的成矿模式，并认为成矿作用可能经历了两个重要阶段，即早古生代岛弧型细碧岩-石英角斑岩建造形成过程中成矿元素的初始富集和晚古生代岩浆活动最终导致成矿。

The ore-forming materials were mainly derived from the volcanic rocks, the spilite providing quite more Cu, and the quartz keratophyre providing quite more Pb, while the spilite, keratophyre, and quartz keratophyre possibly providing quite more Au and Zn.

成矿物质主要来源于火山岩，其中细碧岩可能提供较多的Cu，而石英角斑岩可能提供较多的Pb，Zn的来源则相对较广，细碧岩、角斑岩、石英角斑岩均提供较多的Au。

The genesis and evolution of spilite-quartz keratophyre formation are discussed through studies on Sm-Nd, Rb-Sr, K-Ar isotopic characteristics of the volcanic rocks and its geological setting, and comprehensive studies of petrology, lithochemistry, trace element, REE characteristics of the volcanic rocks.

从Sm-Nd、Rb-Sr、K-Ar同位素年代学和区域地质背景以及岩石学、岩石化学、微量元素、稀土元素等方面探讨了细碧岩-石英角斑岩建造的成因及演化。

Iron deposit is concerned with spilite keratophyre, rich in Fe, Na〓O, Alternative types are similar-skarnization, Iron deposit is of aeromagnetic anomaly. Indexes of Cu, Pb-Zn deposits are contemporaneous fault, ore-bearing bed, volcanic rock with high potassium, volcanic structure, a serious of alternative in ore-bearing bed and under ore-bearing bed, high content of Pb, Zn, Ag, Cu, Cd, Ba, As, CaO, Fe, Mn, low Na〓O, Al〓O〓 in mineralizing body.
