| 中文摘要: |
| 双河铁矿经多年采掘,资源已近枯竭。2013—2015年对矿区及外围进行了详查工作,现矿床已达中型规模。矿区内铁矿体呈层状、似层状分布于鞍山群大峪沟组磁铁石英岩—角闪岩带中,主要矿石矿物为磁铁矿,少量为赤铁矿,具典型的条带状构造,矿床平均品位TFe34.43%；矿床主要受控于鞍山群大峪沟组地层、早期褶皱构造及区域变质作用等因素,矿石自然类型为磁铁石英岩型,矿床成因类型属典型的鞍山式—沉积变质型铁矿。 |
| 英文摘要: |
| The Shuanghe iron deposit is nearly exhausted after many years of mining production. Based on the exploration work during a period from 2013 to 2015 in the deposit area and its periphery area, the Shuanghe iron deposit tonnage reaches the medium-size iron deposit. The iron orebodies occur in Dayugou formation magnetite quartzite- amphibolite of Anshan group in layered and stratoed forms. The main ore mineral is magnetite with minor hematite. The iron ore has a typical banded structure and the average iron grade is TFe 34.43%. The deposit is mainly controlled by Dayugou formation strata of Anshan group, early fold structure and regional metamorphism. The ore type is magnetite quartz, and the genetic type of the deposit belongs to Anshan type sedimentary metamorphic type iron deposit. |
