大跃进以来,为满足钢铁工业需要,在以钢为纲的带动下,根据大中小并举方针,我队勘探了某河流沉积砂铁矿床。今将该矿床的勘探经验介绍如下。一、地质简介本矿床系由原生之(?)钛磁铁矿及含铁角辉岩(花(?)闪长岩与辉长岩之混合岩)经风化沉积而成。原生(?)钛(?)铁矿:呈细网脉状分布于角辉岩节理裂隙中,含矿带最长者不过150米,一般均很 Since the Great Leap Forward, in order to meet the needs of the iron and steel industry, with the steel as the key link, our team explored a river sedimentary sand-iron deposit in accordance with the guidelines of both middle and small scale. The exploration experience of this deposit is as follows. I. Introduction to Geology The deposit is formed by the weathering and deposition of native (?) Titanomagnetite and hornblende (mixed rock of diorite and gabbro). Primary (?) Titanium (?) Iron Ore: Fine Mesh veins are distributed in horn-horn rock joints and fissures, but the longest ore-bearing zone is only 150 m
