摘要
根据不同地质体在不同波段上的光谱特征 ,选择不同波段的TM数据进行假彩色合成、主成分分析、匹配滤波及多种处理方法 ,对淖毛湖戈壁琼河坝地区的线环构造特征、赋矿岩层、矿化蚀变等示矿要素进行增强处理和特征提取 ,取得较好效果 ,为在戈壁地区快速追踪找矿信息、指导成矿预测提供了重要的基础资料。
Based on the spectrum characteristics of differ ent geological bodies in different bands, the optimum bands of TM are selected f or pesudo-color composite, principal analysis,and filter matching. Using above methods in combination with multi-image processing techniques,the signatures of linear and circular structures,ore-hosting strata and alteration in Naomaohu a re remarkably enhanced and extracted. The satisfied results have been obtained a nd important basic information is provided for quickly tracing prospecting and p rediction of ore deposits in gobi area.
