本文主要研究内容
作者沈乐（2019）在《南陵-宣城矿集区典型矿床定量预测指标分析和成矿预测》一文中研究指出：随着地质野外踏勘和科研工作的开展,地质资料、图件也在爆发式增长。在大数据时代来临的现在,大数据的思维和方法已经开始与各个学科相结合,也给地质学提供了前所未有的良好契机,使多年积累的资料成果有了深入发掘利用的可能。本文选择了长江中下游具有找矿前景的南陵-宣城矿集区,系统化收集了本区的代表性矿床——姚家岭锌金多金属矿床和铜山~荞麦山铜硫钨矿床的已有资料。以前人的姚家岭锌金多金属矿床三维实体模型为参照和方法实验,对铜山~荞麦山铜硫钨矿床进行了完整的三维建模、成矿预测指标分析和成矿预测工作。对比研究了显式建模和隐式建模方法,选择客观性更强的隐式建模进行了铜山~荞麦山铜硫钨矿床三维模型构建;并使用了三维欧式距离场分析、空间相关程度定量化分析和三维隆起和凹陷形态分析等三维空间分析方法,挖掘了矿床有利成矿要素;最后基于证据权重法预测模型进行了成矿预测的探索,提出了找矿靶区。在论文工作中取得了如下成果:(1)从建模方式对比研究发现,显式建模方法要求建模人员对研究区数据有较深刻的了解和认识,模型易受人为因素影响,不确定性较大;但若建模人员地质矿床知识丰富对建模矿床了解深入则建模更为准确。而隐式建模方法更适用于数据稀疏区域,由于其对建模技巧的依赖性少,建模方式更加便捷,受人为因素的影响较小,但准确定可能受影响。(2)矿床定量预测指标分析结果表明,姚家岭锌金多金属矿床的铅锌、金、铜的产出与石炭纪和二叠纪地层、隐爆角砾化岩石特别是角砾化斑岩和角砾化大理岩关系非常密切,而金和铜的产出与角砾化灰岩也有一定关系;铜山~荞麦山铜硫钨矿床的铜、硫矿产的产出与石炭纪地层和五通组、闪长岩关系非常密切,而金和铜的产出与角砾化灰岩有一定相关性。分析结果与传统地质矿床学手段勘测的地质矿床情况基本吻合。(3)三维成矿预测表明,本文所采用相关建模、数据挖掘和证据权重成矿预测法具有使用意义。本文所采用的矿床定量预测指标分析对于地质数据使用的客观性得到加强,但是其用作成矿预测的准确性还有待提高。本文使用的数据的定量分析的三种方法虽然有效,但是还可以进行更多的尝试。本文使用了证据权重法进行成矿预测,其预测结果虽然具有使用意义但还可以使用其他方法进行验证。
