| 中文摘要: |
| 文章初步总结了黑河上游地区铁矿分布特征,按其地理分布、成矿时代、含矿建造及成矿地质特征,可划分为走廊南山铁矿带(北带)和托勒山铁矿带(南带)两个成矿带,含矿岩系为泥钙质硅质板岩,层位延伸较稳定,具有一定的层控性,矿石具明显层纹状、条带状构造,其铁矿床成因类型为热水沉积变质型。通过对矿床成因和成矿地质条件分析研究,总结出了该地区成矿找矿模式,提出了进一步的找矿方向。 |
| 英文摘要: |
| The distribution characteristics of iron deposits in the upper stream of the Black River, Qilian mountain range are preliminarily summarized in the paper. The iron deposits mainly distribute along two sub-belts in the region. The host strata mainly is mud calcareous siliceous slate which extends stable in layer form, therefore the deposit has the characteristics of strata-bound type. The ore texture has apparent laminar and banded structures. The iron deposit is classified into the metamorphic hydrothermal sedimentary deposit. Based on the study of deposit genesis and ore-forming geological conditions, the metallogenic and prospecting models in this area were set up, and prospecting targets were outlined for further exploration in this region. |
