In this study , we have collected a mass of pertinent data , such as the geological , the mineral , the geophysical and the geochemical , etc . , 本文收集了云南澜沧江铜成矿带的地层、矿产、地球物理和地球化学等资料，研究了区域成矿规律。
Wudi has three world - rare shell placer deposit belts . stretching a total distance of 56 kilometers , these deposits have total reserves of 360 million tons 无棣县拥有3条长56公里，总地质储量3 . 6亿吨世界罕见的贝壳沙矿带，具有很高的开采利用价值。
Building size of project to this mineralization zone the forecasted stock size totals up to 0 . 183 billion tons . it is divided into two parts with each part is 92 million tons 项目建设规模:该矿带预测资源量合计1 . 83亿吨，分为两块，每块可达0 . 92亿吨。
5 . yulong - mangkang and leiwuqi - zuogong metallogenic belts are formed in collision - orogeny circumstance , and the ore - forming process is related with lava - thermal fluid tightly 张性火山岛弧环境下形成了德格?乡城成矿带，成矿与火山沉积作用密切相关。
Located in the central part of the qianhe - miaoling - manyu metallogenic belt , the xiaonangou deposit in songxian county is a typical tectonic altered rock type gold deposit 摘要嵩县小南沟金矿床位于前河庙岭蛮峪成矿带中部，是典型的构造蚀变岩型金矿床。
Compared with other kinds of ore deposits , zinc - tennantite is a kind of typomorphic mineral in the altai mineralization province and is useful for the exploration of volcanogenic massive sulfide deposits 与其他各类矿床相比，锌砷黝铜矿是阿舍勒黝铜矿的主要类型，也是阿尔泰成矿带的主要黝铜矿类型。

This paper systemically contrasts and analyses the background value and its distribution , the relationship between element enrichment and ore - foming of the four units 依据1 ： 20万水系沉积物测量数据，对比分析了主要成矿元素在整个成矿带及4个构造单元的背景值、元素的空间分布规律、元素富集特征及其与成矿的关系等。
As the degree of study at this place is low , especially the study of law is lack and the forecast means fall behind . so there has been no big breakthrough up to now in gold exploration 由于该区研究程度较低，尤其是成矿规律方面的研究相当薄弱，找矿预测方法手段落后，因此该矿带上的找矿工作始终没有较大突破。
The nw yunnan area is one of the famous tectonic - metallogenic regions in southwestern china , and a series of engineering problems always occur because of the existence of altered rocks formed by hydrothermal action 摘要滇西北地区是中国西南地区最重要的构造成矿带之一，与其相伴出现的蚀变岩常引起一系列工程问题。
