1区域地质背景德勒诺尔铁矿勘查区,其构造属性位于祁连山造山带中祁连陆块区。属中祁连铁、铜、铬、镍、钨、钼、铅锌成矿带,该带位于平达坂深大断裂带两侧,中、上元古界地层发育,主要分布有长城系南白水河组(Chn)、蓟县系花儿地组(Jxh)、青白口系五个山组(Qnw)和哈什哈尔组(Qnh)、寒武系香毛山组(∈xm)及新生界覆盖层。地层褶皱轴向以EW向或NEE向为主,南北翼基本对称,倾角60~70°。伴随强烈的挤压褶皱,形成了一组与褶皱轴向大致平行的压性逆断层。区内岩浆
1 Regional Geological Background In the Geological Exploration Area of Dele Nuer, its tectonic attribute is located in the Qilian block area in the Qilian orogenic belt. It belongs to the mid-Qilian iron, copper, chromium, nickel, tungsten, molybdenum and lead-zinc metallogenic belts. The belt is located on both sides of the Pingda Sakae deep fault zone. The middle and upper Proterozoic strata developed mainly in the south of the Great Wall Chn, Jxh, Qnw and Qnh, Cambrian Xiangmushan Formation (∈ × m), and freshmen Boundary layer. The stratigraphic fold axis is dominated by EW or NEE, and the north and south wings are basically symmetrical with dip angles of 60-70 °. Along with the intense extrusion folds, a group of compressive thrust faults are formed that are approximately parallel to the fold axis. Area magma
