| 中文摘要: |
| 四川红格钒钛磁铁矿是我国重要的岩浆岩型铁矿石产出基地。在过去几十年中，对红格地区进行了不同程度的勘探，积累了大量地质、物化探资料。但是，这些工作比较分散，不同单位不同时期用多种方法开展了多种比例尺的地质、物化探工作，资料零散的分布于不同单位，没有进行过系统的梳理及研究。本文对红格矿区进行有地质约束的三维磁异常反演，建立了三维地质模型，并实现了三维可视化。分析所建三维地质模型，从宏观上推测了红格铁矿的成矿控矿规律及岩浆运移通道，微观上预测了红格矿区矿体空间位置、形态及控矿、容矿、含矿地质体的分布规律。另外，结合地质模型还进行了找矿潜力评价，分析了矿区外围和深部的找矿前景。 |
| 英文摘要: |
| The Hongge vanadium-titanium magnetite deposit is one of significant iron ore outputs in our country. In the last few decades, exploration of varied degrees have been conducted in this area, accumulating a large number of geological, geophysical and geochemical data. However, these surveys are relatively scattered, with data collected in different institutions at different times, using a variety of methods on various scales. These data have not been processed in a systematic way. In this paper, geological constraint is adopted to perform three-dimensional inversion of magnetic data and a 3D geological model is constructed for the Hongge mine area, And 3D visualization is realized. By the analysis of the 3D geological model, the laws of mineralization and ore controlling and metallogenic magma migration pathways are inferred, and the spatial positions and morphology of ore bodies, as well as regularities of ore control, ore capacity and the distribution of ore-bearing bodies are predicted for the study area. Moreover, in combination with the geological models, prospecting potential of this mine is evaluated and the ore-search prospect of the perimeter and deep subsurface of this area is also analyzed. |
