都兰地区位于柴达木盆地东缘,交通尚称方便,是本省目前探明铁矿储量较多的地区之一。该区铁矿主要为与中酸性岩类有关的矽卡岩型铁矿,已探明储量××××万吨,其中(宀夫)矿储量>××××万吨,中型矿床二处,小型矿床十余处。区内构造活动频繁强烈,中酸性岩类广泛侵入,为形成矽卡岩型铁矿提供了良好的成矿条件,所以研究本区此类型铁矿扩大(宀夫)铁矿的远景,有着重要意义。现将本区铁矿的展布规律及成矿予测等问题讨论
Dulan region is located in the eastern edge of the Qaidam basin, the traffic is still said to be convenient for the province is currently proven iron ore reserves in more areas. The iron ore in the area is mainly skarn-type iron ore related to medium-acidic rocks. The proven reserves are ×××× 10,000 tons, of which the ore reserves are more than ×××× million tons and the medium-sized deposits have two , More than ten small deposits. The intense tectonic activity in the region and the extensive intrusion of moderate-acidic rocks have provided good metallogenic conditions for the formation of skarn-type iron ores. Therefore, it is important to study the prospect of expanding such iron ore mines in this area. significance. We will now discuss the distribution of iron ore in the area and the mineralization and other issues to be discussed
