| 摘 要： | 本文利用航空高光谱CASI数据和岩石的光谱特征,提出一种快速提取富含Fe2+岩石信息的算法,并由此获取辉绿岩脉信息。经过实地验证,数据处理结果的精度较高,处理结果中辉绿岩脉规模及其走向等特征清晰。将提取的结果与铀矿异常信息对比分析,发现富含Fe2+的辉绿岩脉与铀异常具有很强的相关性。通过利用这种方法,在研究区南部又新发现了两条辉绿岩脉构造。

| Abstract: | Based on aerial hyperspectral CASI data and the spectral characteristics of rocks,an algorithm was proposed for extracting the information of rocks which is rich in Fe2+ in the paper.Then this method was used for obtaining the information for diabase dikes.The field result proved that the precision of this method was very good,as the scale and trend of diabase dikes and other features were very clear.After analyzing the extracted results and the information of Uranium anomalies,it was found that Diabase dik... |
