摘要/Abstract

摘要： 根据SAI光谱吸收指数模型(王晋年,1996),本文分析金、铜矿主要蚀变矿物光谱曲线特征参量,并对其光谱吸收特征进行量化。其主要量化指标是：SAI、吸收宽度、吸收深度、吸收位置、吸收对称性。以ENVI为平台综合ENVI函数与IDL语言开发了蚀变矿物信息提取模块MineralExtractModule。通过实验区验证证明本模块能够根据光谱吸收特征快速并精确地识别出与矿化有关的蚀变矿物，实现了利用成像光谱技术快速并较为准确地提取蚀变矿物信息的目的。

关键词: SAI, 蚀变信息提取模块, IDL

Abstract: According to SAI mineral absorption index model (Jinnian Wang, 1996), this paper analyzes gold, copper spectral curves of the main alteration mineral parameters and quantifies their spectral absorption characteristics. The main quantitative indicators are as follows: SAI, absorption width, absorption depth, absorption position, absorption symmetry. Synthesizing the ENVI function and the IDL language based on ENVI platform develops alteration mineral extraction module MineralExtractModule. In addition the experiment proves that the module can be quickly and accurately identify mineralizationrelated alteration minerals using the spectral absorption features, so realizes the goal of using imaging spectroscopy to extract alteration minerals quickly and automatically.

Key words: SAI, alteration information extraction module, IDL
