为了迅速解决当前国家极需的镍矿,1958年我们在山东某区及其外围地区用化探配合物探(磁法,自然电流,联合剖面,充电法等)展开了寻找镍矿的工作.通过这一工作,对应用化探配合物探寻找镍矿的方向和应采取的手段以及它的地质效果等方面获得了初步的经验.在这里介绍出来,供大家参考.一、矿区地要概况本矿区包括本区、降甘、西九群、岱密菴等地,面积约300平方公里.在大地构造上处于山东古地台的西南边缘.主要岩层为太山杂岩系,即片岩及片麻岩.本区在震且纪以前有过频繁的火成岩活动,先后使入到古老的片麻岩中.这些火成岩有花岗岩、角闪岩、辉长岩、闪长岩、辉绿岩、绿泥石角闪片岩、煌斑岩等.上述的基性岩多成中小型岩体沿北西及北东之裂隙侵入.其中沿北西20°侵入的角闪岩为本区主要的含镍矿岩层.本区构造线主要有两组,一组为北西20°～30°,一组为北东48°方向.以前组为主,为各岩层的片理方向,并为支配早期岩浆活动的要道.也
In order to quickly resolve the nickel ore that is very much needed in the current country, we started the search for nickel ore by using geochemical exploration (magnetic method, natural current, cross-section, charging method, etc.) in a certain area of Shandong and its periphery in 1958. By This work, the application of geophysical prospecting to find the direction of the nickel ore and the means to be taken as well as its geological effects and other aspects of the initial experience gained. Here to introduce for your reference. First, the mining area to profile The mining area Including the area, Jiang Gan, West nine group, Dai Mi Temple and other places, an area of about 300 square kilometers in the tectonics on the southwestern margin of the Shandong ancient platform .Main rock formations for the Taihe complex, that schist and gneiss Rocks have experienced frequent igneous activities before the earthquake and have been successively introduced into ancient gneisses such as granite, amphibolite, gabbro, diorite, diabase, chlorite Rock hornblende, lamprophyre, etc. The above basic rocks and multi-scale small and medium-sized rock intrusions intrude into the fissures of North West and North East, of which the amphibolite which invaded at an angle of 20 ° North-west is the main nickel-bearing rock formation in this area. There are two main tectonic lines in this area, one of which is 20 ° ~ 30 northwest , A group NE 48 ° direction before the main group, a sheet processing direction of the formation, and for the dominant early MAGMATISM arteries also
