基于遥感预测模型的广东省找矿靶区预测与优选

Prediction and preference of prospecting targets in Guangdong Province based on remote sensing forecast model

通过总结广东省矿产地遥感影像构造特征,提出遥感影像异常是重要的找矿标志,建立了主要典型矿田影像模式,通过影像异常类比寻找类似矿床。通过线-环影像结构研究和典型矿田影像模式对比分析,建立遥感预测模型。通过区域成矿规律和遥感找矿五要素研究,根据遥感预测模型,建立不同矿种不同矿产预测类型的遥感预测模式,在广东省范围内圈定了18个矿种235个遥感找矿靶区;进一步缩小找矿有利地段,圈定了58个遥感最小预测区,通过优选遥感找矿靶区,选取6处找矿最有利地段,为广东省矿产资源勘查找矿突破提供遥感选区依据。建议在找矿潜力巨大的6个遥感最小预测区加大勘查投入力度,务求短期内取得找矿重大进展和突破。

The paper summarizes the characters of remote sensing images from mineral deposit areas,and brings forwards that anomalies in remote sensing images are an important prospecting indicator.The study established image models for the primary representative mines,and searched for similar deposits by analogy of image abnormity.We established the prediction model of remote sensing by studying string-ring image framework and the contrast analysis of representative mine image mode.We also set up remote sensing forecast modes for different mine types and mine forecast style,base on the prediction model of remote sensing,by the research of regional meta-llogenic regularities and five remote sensing prospecting indicators.A total of 235 remote sensing prospecting targets for18 mineral species were delineated in Guangdong Province.Furthermore,58 minimum remote sensing prediction areas were determined in order to further reduce the advantageous prospecting regions of seek deposit,which provides remote sensing evidence for mineral exploration in Guangdong Province.Moreover,we selected six optimal prospecting areas,by preferential selection of remote sensing prospecting targets; this will provide remote sensing evidence for the prospecting breakthrough in Guangdong Province.Finally,we suggested increasing perambulation devotion in the zone of six preferential remote sensing minimal predictions areas with an enormous prospecting potential in order to make great progress and prospecting in a short period.
