This paper puts forwards a new kind of technical approach-Band Sequence Structure Analysis (BSSA) by using the
hyperspectral data as the band-series data which have almost continuous sub-band. This new technical approach includes such means
as band sequence histogram, left (right) skew parameter analysis, relevant (similar) matrix and regression skew analysis. In this
paper, the BSSA of hyperspectral data is applied to such fields as statistical character analysis and quality evaluation,
evaluation of potentiality of alteration information, selection of characteristic bands and extraction of mineral alteration
information. The result of the application demonstrates the scientific value and practicality of the new technical idea.
