Study on forest fuel and classification of fire disk level of stand type;

地被可燃物与林型火险等级划分

On the basis of the actual material and data from three gold deposits(Changkeng, Gaolong and Guoti) in Guangdong and Guangxi provinces of China, we suggested that within the sediment-hosted micro-disseminated-type(Carlin-type) gold deposits, there is a subtype which could be called silicalite-type gold deposit.

根据广东和广西 3个金矿床 (长坑 ,高龙和果提 )的资料认为 ,微细浸染型金矿 (卡林型金矿 )中存在一种亚类 ,叫做硅质岩型金矿。

It may be correlated to Carlin-type gold deposit.

笔者认为新发现的川西北某金矿床与热液浸染交代的卡林型金矿床类型可以类比 ,成矿受断裂、破碎带控制 ;赋矿层主要为危关群泥灰岩 ;自然金呈微细粒和显微细粒赋存于黄铁矿、毒砂及褐铁矿之中。

Samples of zonal pyrite collected from the Carlin-type gold deposits in southern Guizhou Province were examined by using electron microprobe and three kinds of pyrite have been classi-fied.

利用电子探针对黔南卡林型金矿床中环带状黄铁矿进行研究，把它划分成三种类型，并分别测定内外带中As、Sb、Au、Hg和Tl等微量元素的含量，绘制了以步间距1μm，横穿环带的这五种元素的X射线强度变化曲线图，图中清楚显示出环带起因于微量元素含量的变化，这五种元素在微观尺度上呈正相关的振荡式变化，具有同源性。

In this paper an integrated geological and geochemical comparison is made of Carlin-para-Carlin type gold deposits in the South Qinling with their associated hydrothermal sedimentary lead-zinc deposits, the Carlin type gold deposits in the Yunnan-Guizhou-Guangxi gold triangle, China, the Carlin gold deposit, Carlin, western United States, and the Muruntau type gold deposit in Uzbekistan.

笔者将南秦岭卡林型—似卡林型金矿床与与其共生的热水沉积成因铅锌矿床、中国滇黔桂卡林型金矿床、卡林型金矿床命名地美国西部卡林金矿床、乌兹别克斯坦穆龙套型金矿床等进行了地质地球化学综合对比研究,可以发现,这些矿床的形成均与现代板块构造活动机制具有密切耦合关系,属于造山期成矿矿床。
