| 中文摘要: |
| 花脑特银多金属矿位于内蒙古锡林郭勒盟东乌珠穆沁旗境内，矿区内共有4条蚀变带，其中Ⅰ号蚀变带为已发现的最大含矿带。为查明花脑特矿区Ⅰ号蚀变带三维地质特征以进行深部盲矿预测，依托CnGIM-ma软件构建了花脑特矿区Ⅰ号蚀变带三维地质模型，包括几何模型和属性模型。通过几何建模，清晰地展示了Ⅰ号蚀变带深部地质结构特征，解决了长期困扰矿山地质人员的岩体侵入接触界面展布问题；通过属性建模，完成了Ⅰ号蚀变带各单元素的三维异常图，并对前缘晕元素（Hg、B、Sb、As）、近矿晕元素（Ag、Pb、Zn、Cu、In、Au）异常在三维属性模型中的综合表达方法进行了研究探索，最后选用“分带赋值法”建立了前缘晕、近矿晕的综合属性异常模型，在已知矿体的深部预测了2个成矿靶区，可与传统构造叠加晕研究预测位置较好吻合。 |
| 英文摘要: |
| The Huanaote silver polymetallic deposit is located in the eastern Ujumuqin Banner of Xilingol League, Inner Mongolia. This deposit contains four alteration zones, and the No. I alteration zone is the largest discovered ore-bearing zone. This work aims to determine the three-dimensional geological characteristics of the No. I alteration zone, which will help to predict deep blind ores in the Huanaote deposit. A three-dimensional geological model of the No.1 alteration zone was constructed based on the CnGIM-ma software, including geometric model and attribute model. Through geometric modeling, the characteristics of deep geological structures of the No. I alteration zone were clearly displayed, which has determined the distribution of the rock mass intrusion contact interface that has long troubled mine geologists. Through attribute modeling, the three-dimensional anomalies of each single element in the No. 1 alteration zone were described. The comprehensive expression method of the front halo elements (Hg, B, Sb, As) and near-ore halo elements (Ag, Pb, Zn, Cu, In, Au) anomalies in the three-dimensional attribute model was studied and explored. And the "zoning assignment method" was selected to establish comprehensive attribute anomaly models for the front halos and near-ore halos, and two metallogenic targets were predicted in the depth of the known ore bodies. |
