According to the time and space corresponding relation of the gold deposits with the key W elevation of Moho shape, the profound faults, the magmatism, the aerial magnetic, gravity anomalous field and the annular structure etc, the ore forming possibility of juvenile fluid is discussed in this paper. The study of isotopic geochemistry such as Pb, S, O, H and Ar indicate that the minerogenetic material source came from juvenile and crustal rock. The gold deposits belong to the products that miscellaneous hot fluid for juvenile fluid and metepric hydrothermal solution transformed crustal rock possibly.
