分形在岩性分类及蚀变信息提取中的应用
|
摘要
为了推进多重分形思想在遥感地质找矿领域的应用,以新疆西准噶尔地区为实验区,通过分析该区的成矿特点与遥感影像特征,构建分形维数谱,并将其与图像光谱特征相结合进行岩性分类与含黄铁矿矿化蚀变信息提取,在现有矿点统计资料与专家经验知识的支撑下,确定找矿靶区。实践证明,基于遥感图像的分形理论并结合图像的光谱特征,建立相应的找矿模型和找矿标志,能更好地为区域矿产勘查提供决策支持。
In order to promote the application of multi-fractal theory to remote sensing exploration,this paper takes the West Junggar Region as the study area to build fractal dimension spectra by analyzing the characteristics of the region and the remote sensing image.Combined with spectra,the authors completed the lithologic classification and pyrite alteration extraction of the region.And then mineral targets of the region was identified with the support of the existing statistical data of mines and expert's experience and knowledge.Practice has proved that the appropriate prospecting model and criteria established on remote sensing images of fractal theory and spectral characteristics can satisfactorily supply decision support to regional mineral exploration.
