Granites have metallogenic specialization. At different tectonic settings and different orogenic stages, granitoids of various types, mineralogical and geochemical compositions, geneses, and differentiation evolutionary histories are formed by melting of different sources, and different zonations, fractures and metasomatisms are produced in granitoid plutons. There is correlation between them and associations of metal elements. Also, they play a key role in controlling mineralization of granitoid. Some diagnostic criteria for mineralized granites are summarized and reviewed, which include tectonic setting, zonation of granite, mobility of ore fluid, and geochemical and mineralogical indicators.
