东天山-北山成矿带高光谱矿物填图数据集

本数据集为西北地区东天山-北山成矿带蚀变矿物地表分布数据（图）产品，主要包括27个标准地质图幅（1：25万）分幅矿物分布图。本数据产品共利用334景国产高光谱遥感卫星数据（GF-5和ZY1）和基于美国地质调查局Tetracorder算法框架自主开发的GeoAHSI矿物填图工具完成。通过地质资料对比和实地采样验证，本数据产品可以在地表30米分辨率的精度上探测出碳酸盐矿物、层状硅酸盐矿物、硫酸盐矿物及混合矿物共计60余种，并能够准确反映各类矿物的空间分布特征。

This dataset is a product of surface distribution data (and maps) of altered minerals in the Eastern Tianshan-Beishan metallogenic belt, Northwest China. It primarily comprises 27 standard 1:250,000 scale geological map sheets, each with a dedicated mineral distribution map. This data product was developed using 334 scenes of domestic hyperspectral remote sensing satellite data (GF-5 and ZY1) and the GeoAHSI mineral mapping tool independently developed based on the algorithm framework of the U.S. Geological Survey's Tetracorder. Through comparison with geological data and field sampling verification, this product can detect more than 60 types of minerals including carbonate minerals, phyllosilicate minerals, sulfate minerals and mixed minerals at a surface spatial resolution of 30 meters, and accurately reflect the spatial distribution characteristics of various minerals.
