Abstract:

On account of the current situation of Chinas increasing demand on energy sources and mineral resources, this article firstly analyzes the challenges encountered by current mineral exploration, summarizes research status of the new mineral exploration technology both at home and abroad, and then systematically introduces the basic concept, research contents and implementation significance of the "Spectral Crust". The paper points out that in the mineral exploration, through the spectral detection of the earths surface and crust surface within the scope of 1 km, the purpose of the "Spectral Crust" plan is to realize the use of hyperspectral technology on geological mapping of the Earths land surface and remote sensing detection of mineral altered information, as well as the spectrum detection of the core, establish the crust hyperspectral database set, and meet the need of mineral exploration using hyperspectral technology. The project of the "Spectral Crust" caters to the needs of national strategy, strengthens technological innovation and application mode innovation, improves the capability of mineral resources detection by spaceborne and airborne hyperspectral remote sensing, establishes the ground spectra measurement platform and spectral scanning, compiling, and analysis platform of the core, develops the integration of aerospace, aerial, surficial and belowground core based remote sensing stereo detection system. This project has great strategic significance and prospecting value, is the top design of hyperspectral remote sensing technology development, will solve the two big challenges of direct prospecting and deep prospecting and promote the development of whole countrys mineral exploration technology.

Key words: mineral exploration, hyperspectral exploration, the Spectral Crust
