右江造山带北缘吴家坪组灰岩中卡林型金矿的发现及其意义——以贞丰县毛安、播老金矿为例

Carlin-type Gold Deposit Found in the Limestone of the Wujiapin Formation on the Northern Margin of the Youjiang Orogenic Belt and Its Implication: A Case of the Mao'an and Bolao Deposits,Zhenfeng County

位于右江造山带北缘的毛安、播老等地,发现了上二叠统吴家坪组灰岩中的卡林型金矿,丰富了黔西南卡林型金矿的赋矿层位,本文从描述该类型金矿的矿床地质特征,分析了该类型金矿的成矿地质条件,探讨其地质意义,并对下步找矿提出建议,可供借鉴。

The Carlin - type gold deposits in the limestone of Upper Permian Wujiaping Formation, located in the Mao＇an and Bolao fields on the northern margin of the Youjiang orogenic belt, have been found, which enrich ore - bearing horizons of the Carlin - type gold deposits in southwest Guizhou. This paper studies metallogenic geological condition and discusses its geological implication based on description of geological characteristics in this paper, as well it puts forward the suggestion for further prospecting with the purpose of providing reference.
