【摘要】 基于蚀变矿物所含有离子或基团的诊断波谱特性和场的理论,对蚀变信息机理研究,认为蚀变作用与热水溶液的温度、压力及周围构造发育情况密切相关而具有场的特征。蚀变信息是由波谱信息与空间信息两部分组成,其中典型蚀变矿物所含离子或基团的波谱信息构成波谱特征向量,纹理的空间分布概率构成空间特征变量,因而提出蚀变信息场。蚀变信息场充分利用多光谱遥感数据中的空间维与波谱维信息,实现了遥感信息提取理论与地学蚀变作用理论的有机结合。更多还原

【Abstract】 Based on diagnostic spectral characteristics of the ions included in altered minerals and field theory,the authors believe that the alteration occurred in a rock body particle and is closely related to the temperature,pressure and surrounding structure of hydrothermal deposits,and has the field characteristics.The alteration information is composed of both spectral and spatial information.The spectral characteristic vectors are composed of the ions spectral information included in representative alteration minerals and the spatial characteristic variable is composed of texture spatial distributing probability.So the alteration field information theory has been put forward.The theory can fully use the spatial and spectral dimension information of multi-spectral remote sensing data and implement the full integration of remote sensing alteration information extracting theory with alteration theory of geosciences.更多还原
