Most known exposed porphyry Cu-(Mo-Au) deposits in east China districts have been discovered．Present-day how to exploration is focused on searching for covered deposits，and re-assessment deposits in known explored district．It is an important for exploration geologists to require knowledge of geological history on a regional scale and an understanding of magmatic-hydrothermal deposits in the various tectono-magmatic setting，in addition to a deposit-scale appreciation of ore-forming processes．This paper is just pay attention to intuduce the knowledge and advancing on types，characteristics，and mineralizing patterns of the hydrothermal deposits related to shallow and deep-seated plutonism，volcano-plutonic and volcanic complexes in the environment of the plate collision， and post-orogenic extension from domestic and oversea geologists．This content also includes definitions and types of hydrothermal systems， fluid compositions and natures，intrusion types and its morphology characteristics， from magmatic，magmatic-meteoric，predominantly meteoric hydrothermal system，as well as alteration characteristics due to fluids，and fluid-wall rock interaction controlled by various depths and temperatures，and so on．
