Simply Discussing the Geology Forming Condition of Placer Gold Mineral Deposit

The geological chemical characteristics of the external condition to form placer gold,the carry medium,the power condition,the relationship between the structure condition and the formation of placer gold deposit,the influence of physiognomy condition,the condition of supply source of placer gold,the preservation of placer gold were discribed.Studying the laws of formation of placer gold deposit and metallogenic geological conditions of different placer gold deposits will have tremendous economic significance toward further searching valuble industrial placer gold orebody and expanding reserves.Meanwhile,the discovery of placer gold deposit often serves as instructive mark of primary gold deposit;therefore studying its metallogenic geological characteristics has great geological significance.
