花岗岩接触带热液成矿理论著述众多，然而多调强由岩浆热中心向外的热液流，而往往忽视由岩浆热场引起的，从围岩向热中心的内向热液流的作用。外向型与内向型热液流的双向汇聚是造成接触带热液成矿多样性的重要原因。环绕岩体的双向汇聚成矿元素增长带与围岩矿源层叠加部分———双控矿质富集区是热液成矿的最佳区段。然而，富集区并非固定不变，它是随岩浆热场演化而向外推移和向内收缩，直到岩体内部。矿床的定位与成矿时期有关，受地质构造控制明显。
Although there are many works on hydrothermal mineralization in the contact zone of granite, the hydrothermal flow from the magma thermal center is mostly emphasized and the inward hydrothermal flow from the surrounding rock to the thermal center is often neglected. Bidirectional convergence of extroverted and introverted hydrothermal fluids is an important reason for the mineralization diversity of hydrothermal fluids in the contact zone. The two-way convergent ore-forming elemental growth zone and the surrounding rock source zone superimposed on the surrounding rock bodies --- the double-controlled mineral enrichment zone is the best section for hydrothermal mineralization. However, the enrichment area is not static, it is outward evolution and inward shrinkage with the thermal evolution of the magma, until the interior of the rock mass. The location of the deposit is related to the ore-forming period and obviously controlled by the geological structure.
