| 摘 要： | 通过对埃塞俄比亚地层、构造、岩浆岩及矿产分布与特征的研究,初步认为：①埃塞俄比亚的地质研究程度普遍偏低,尤其基础地质及其成矿作用和成矿规律方面急需开展重点研究。②地层单元可划分为3类,分别为前寒武纪基底岩系、晚古生代—中生代沉积岩系和第三纪—第四纪火山岩沉积岩系,大地构造位于＂泛非构造带＂中的东非造山带,多期次构造岩浆活动强烈。③前寒武纪变质岩区主要矿产为金、铂、稀有金属、镍、铜、铁、铬、高岭土、长石、黏土、石棉、滑石、大理岩、花岗岩等;中生代沉积岩区主要有石灰岩、砂岩、石膏、黏土、油气资源等;新生代火山岩沉积岩区主要有褐煤、蛋白石、油页岩、红土型铁矿、斑脱土、黏土矿、珍珠岩、硅藻土、钾盐、石盐、油气及地热资源等。

| Abstract: | Through study on strata,structure,magmatic rocks and distribution and characteristics of mineral resources in Ethiopia,it is regarded that： ① the degree of geological research in Ethiopia is generally low,especially basic geology,mineralization and mineralization rule are urgently needed to be studied.② stratigraphic units can be divided into three categories,namely the Precambrian basement rocks,late Paleozoic-Mesozoic sedimentary rocks and Tertiary-Quaternary volcanic sedimentary rocks.Tectonic structures locate in the eastern African orogenic belt in the ＂universal Africa tectonic belt＂ with strong multi-stage magmatic activities.③Major mineral resources occurred in Precambrian metamorphic rock areas are gold,platinum,rare metals,nickel,copper,iron,chromium,kaolin,feldspar,clay,asbestos,talc,marble,granite,etc.,while mineral resources in Mesozoic sedimentary areas are limestone,sandstone,gypsum,clay,oil and gas resources.Mineral resources in Cenozoic volcanic rocks area are lignite,opal,oil shale,laterite iron ore,bentonite,clay mineral,perlite,diatomite,potash,stone salt,oil and gas and geothermal resources. |
