摘要
雅鲁藏布江缝合带是我国寻找铬铁矿的最有潜力地区,位于其东段的罗布莎岩体中的罗布莎铬铁矿为我国最大的铬铁矿矿床。罗布莎铬铁矿矿床根据地质特征及铬铁矿矿化特点分为北部边缘矿带、南部边缘矿带及中部矿带,矿体赋存于斜辉辉橄岩岩相带中。泽当岩体与罗布莎岩体相邻,两岩体的地幔橄榄岩具有相似的起源且蛇绿岩的形成时代相近,在泽当岩体中找到富矿的纯橄岩—方辉橄榄岩岩相带的可能性很大。
The Yarlung Zangbo Suture Zone is the most promising area for chromite prospecting in China. The chromite chromite in the Lop Nur rock mass in the eastern part of the Yangtze River is the largest CHROMITE DEPOSIT IN China. The LUOBUSHA CHROMITE DEPOSIT according to the geological characteristics and mineralization characteristics of chromite ore belt, divided into the northern edge of the southern edge of the ore belt and central ore belt, ore bodies occur in Xiehui harzburgite facies. Zedang LUOBUSHA and adjacent rock rock, two rock mantle peridotites have similar origin and age of the ophiolite is similar to find rich dunite and harzburgite facies in Zedang rock in great possibility.
