摘要
简要介绍了白云鄂博矿区矿床地质概况,阐明了白云鄂博矿床资源丰富,铁矿体规模巨大。据前人地质工作成果显示,东矿体呈枝叉状尖灭于白云岩和黑云母化板岩中,深部变窄分叉尖灭于白云岩中,最大延深890 m。通过东矿体深部探矿揭示的矿体特征,结合前人工作资料认为:①东矿体严格受层位控制;②东矿体具有"沉积成矿"的主体成矿过程这一特性;③东矿体分布在向斜构造的北翼及其核部,并与南翼东介勒格勒矿体相连,且与主矿、西矿是同一构造体系;④东矿体在深部厚度变化不大,仍有向下延伸的趋势。根据以上几点认识推测在白云鄂博主、东、西矿深部存在较大储量的铁矿石资源。
The geological conditions of Baiyunebo deposit area are outlined, which has rich resource and enormous iron orebodies. The previous exploration results show that the east orebody dies out in branching in dolomite and biotite slate and in dolomite at depth in narrowed branching, with a maximum extension of 980m. It is concluded through the orebody characteristics disclosed by the deep exploration of the east orebody and in combination with the pervious work that ： 1 ） the east orebody is strictly controlled by the strata; 2） its main mineralization process has the character of ＂sedimentary mineralization＂ ; 3 ） the east orebody is distributed at the north wing and the core of the syncline structure , joins with the south east Dongjielegele orebody and belongs to the same structural system as the main orebody and west orebody; 4） it changes little in the thickness at depth and has a tendency to extend downward. According to the above understandings, it can be conjectured that there is large reserve of iron ore in Baiyunebo main, east and west orebodies at depth.
