甘肃省铁矿主要分布于北山、祁连山及秦岭区,其中以沉积变质型及沉积型铁矿最重要,占总储量的极大部分,沉积变质型主要分布于祁连山区;而沉积型主要分布于秦岭区。接触交代型与热液型以及火山岩型铁矿则主要分布于北山区,次为西秦岭与祁连山区,为富矿的主要对象。此外尚有岩浆型钒钛磁铁矿点,但规模均较小。本文主要据甘肃省1972年1∶50万编图资料加以整理,其中利用了省地质局文蜀屏及区测二队梁鼎新、刘晓祥等同志整理的资料。由于我们政治与业务水平所限,错误之处,请批评指正。
Iron deposits in Gansu Province are mainly distributed in the Beishan, Qilian Mountains and Qinling Mountains, of which sedimentary metamorphism and sedimentary iron ore are the most important and account for a large part of the total reserves, and the sedimentary metamorphic types are mainly distributed in the Qilian Mountains. The sedimentary types are mainly distributed in Qinling District. The contact metasomatism and hydrothermal types and the volcanic type iron ore are mainly distributed in Beishan area, followed by the West Qinling and Qilian mountains, which is the main target of the rich ore. In addition there are magmatic vanadium titanium magnetite point, but the size is small. This article is mainly based on Gansu Province 1: 500000 in 1972 to compile the compilation information, which uses the Provincial Bureau of Geology Wen Shu screen and regional measurement team Liang Dingxin, Liu Xiaoxiang and other comrades finishing information. Due to our limited political and operational level, the wrong place, please comment on criticism.
