      [摘要]文章针对矿产资源GIS 评价中成矿信息尤其是地质信息提取不充分的问题,提出了一种 基于场模型的成矿信息提取方法即成矿信息场分析方法,并以桂西-滇东南地区锰矿为例进行了成矿信 息的场分析提取实例研究。通过成矿信息的距离渐变性和影响叠加性的特征分析,引入场论概念,讨论 了成矿信息的场模型表达方法,包括成矿影响场模型和成矿距离场模型。利用场论叠加原理和空间距 离分析方法,借助参数方程和积分方法,推导出了地质体(点状、线状和面状)的成矿影响场数学模型和 成矿距离场数学模型。在成矿背景分析的基础上,利用成矿信息场分析方法,建立了同生沉积断裂和成 锰沉积盆地的成矿信息场模型,分析了同生沉积断裂和成锰沉积盆地的成矿信息场与锰矿化分布的空 间关联关系。实例分析表明,成矿信息场分析方法可有效地提取研究区同生沉积断裂、成锰沉积盆地的 控矿信息,提取结果具有显著的统计效果和明确的地质意义。
英文摘要:
      Abstract:Focusing on the issue of inadequate extraction of metallogenic information especially geological information, this paper proposes a new method of extracting metallogenic information based on field model, i. e. the method for field analysis of metallogenic information, and made an case study of the extraction of metallogenic information with the method by taking the western Guangxi and southeastern Yunnan areas as an example. The presenta鄄 tion method for the field models of metallogenic information, including the metallogenic influence field model and the metallogenic distance field model, is discussed under the field theory by analyzing the presentation ways of the distance gradualness and the influence superposition of metallogenic information. According to the field theory superposition principle and the spatial distance analysis method, the mathematical models for the metallogenic influence field and the metallogenic distance field of point, line and area geological bodies are deduced by using parameter equation and calculus. Based on the metallo鄄 genic background analysis, the metallogenic information field models of synsedimentary faults and manganese sedimentary basins are built, and the correla鄄 tion relationship between the metallogenic information fields and the manganese mineralization distribution is investigated, by using the method of metallo鄄 genic information field analysis. The case study indicates that the method of metallogenic information field analysis is useful for extracting the ore-control鄄 ling information of synsedimentary faults and manganese sedimentary basins in the study area, and that extraction results are both statistically and geologi鄄 cally significant.
