%X Weathering crust is an interaction interface between the lithosphere, the atmosphere, the hydrosphere and biosphere, and thus keeps abundant information concerning the evolution of the Earth's multi spheres. It is a traditional work to reconstruct palaeogeographical conditions according to the zonal principle and the signals distilled from the weathering crust. Recent successful application of the laser 40 Ar/ 39 Ar dating technique of single crystal and "double surface" model to weathering study pioneers a new aspect of research on global change. The synthetical study of weathering crust can not only yield high resolving records of environmental change in denudation areas of continents, which provide a wide perspective for comparison of weathering episodes (events) with others global tectonic climate events, but also redound to an accurate quantification of weathering processes, which is in favor of a profound understanding of coupling relationship between tectonics, weathering, denudation and climate and an appropriate estimation of human impact on future climate.
