Abstract:

In order to effectively guide further exploration,we study the metallogenic regularity of Boka gold deposit in Yunnan Province.On the basis of previous work,combining the field investigation and previous data studied further,we summary the characteristics of Xinshan-Majiagou gold deposit,analysis the ore-controlling factors,discuss material source and formation mechanism of the Xinshan-Majiagou,conclued that gold deposit belonged to gold broken alteration type gold deposit,establish the signs of the ore prospecting for the Xinshan-Majiagou gold deposit,which can effectively guide the next exploration.

Key words: Boka gold deposit, Deposit characteristics, Ore-controlling factors, Formation mechanism
