本区大地构造位置属于天山—内蒙—兴安地槽褶皱区内蒙古中部地槽系,苏尼特右旗晚华力西地槽褶皱带、锡林浩特中间地块锡林浩特—二道井复背斜西端南翼次一级复式向斜构造带中,由于受区域构造的控制,区内地层、侵入岩构造形式呈东西向展布。该矿床受控于下中志留统的第三、五岩段中,矿层与石英岩和含铁石英岩,严格受层位控制。矿床成因为沉积变质矿床。SiO2含量多,TFe平均含量36.56%,属低贫铁矿。通过该矿地质特征及矿床成因的探讨总结成矿规律。
The tectonism of this area belonged to the central Trench System of Inner Mongolia in the Tianshan-Inner Mongolia-Xing’an Trough Fold Zone, the Sunvarian Banner of the Late Western Lvliu Gorge Fold Belt in the Xilinhot Middle Block, and the western wing of the Xilinhot- In the sub-level synclinal structure belt, due to the control of the regional structure, the regional strata and intrusive rock structures are distributed east-west. The deposit is controlled by the third and fifth rocks of the Lower Middle Silurian, and is controlled by layers strictly in the ore layers, quartzite and iron-bearing quartzite. Deposits because of sedimentary metamorphic deposits. SiO2 content, TFe average content of 36.56%, is a low-iron ore. Through the geological characteristics of the deposit and the discussion on the genesis of the deposit, the metallogenic regularity is summarized.
