商南松树沟超基性岩体位于北秦岭东段南侧豫陕交界处,长18.5公里,中部最宽2.2公里,面积约20平方公里。从一九五七年开始,该岩体及铬矿经有关地质、物探和科研等单位的详细工作,特别是陕冶七一三队的勘探和研究,为国家提供了一定的铬矿储量。为了查明矿区远景,扩大储量,以满足矿山开采的急需,一九七六年我们配合陕冶七一三队和陕冶地研所,对该岩体及铬矿的成矿规律和找矿标志共同进行了研究。由于时间短,岩体规模较大,资料很多,因此我们只能在学习和综合分析前人的主要工作成果及认识的基础上,通过实际调查,按照为进一步找矿评价工作指出方向的任务要求,对其主要地质问题进行重点研究。
The Shangnan Songshugou ultrabasic rock mass is located at the junction of Henan and Shaanxi on the southern side of the eastern section of North Qinling Mountain, with an elevation of 18.5 kilometers and a maximum width of 2.2 kilometers and an area of about 20 square kilometers. Since 1957, the rock mass and its chromium ore have provided some reserves of chromium ore to the country through the detailed work of geologic, geophysical and scientific research units, in particular the exploration and research of the Shaanxi 717 Group. In order to ascertain the prospect of the mine area and to expand its reserves to meet the urgent need of mining, in 1976, in cooperation with the Shaanxi 731 team and Shaanxi Metallurgical Research Institute, we investigated the metallogenic regularity and ore prospecting of this rock mass and chromite Logo jointly conducted a study. Due to the short time, the rock mass is large in scale and there are many materials, we can only study and comprehensively analyze the main achievements and understanding of predecessors, through actual investigation, according to the mission requirements that point out the direction for further prospecting and evaluation , Focusing on the major geological problems.
