The determination of lithosphere thickness is not only useful for the study of its origination and evolution character,but also very helpful for the explanation of its shallow response to different underlying mantle convection and surrounding plate tectonic.We present a rapid method based on the assumption of lithosphere local isostasy and use CRUST1.0 model to map the global lithosphere thickness.By comparing with the latest research results of global thermal lithosphere and regional seismic lithosphere thickness,it is conformed that our results has some practical significances.The distribution of global lithosphere thickness shows the following properties: (1) The thickness of oceanic lithosphere has positive relationship with the geological age of oceanic crust.Around mid-oceanic ridge,the youngest lithosphere on earth has a lithosphere thickness of about 40kilometers.The farther the distance from mid-ocean ridge,the older of oceanic geological age,and the thicker of corresponding lithosphere thickness, when the oceanic geological age is of 120 million years,the corresponding lithosphere thickness reach 110kilometers.The cooling plate model is a perfect model to explain the distributing characteristic of oceanic lithosphere. (2)The lithosphere heterogeneity is more complicate in the continental area. Generally,the stable craton has a thicker lithosphere root ranging from 120to 220 kilometers,and the lithosphere thickness of craton has a nearly positive relationship with its geological age,like in Africa,the Archean craton has the thicker lithosphere root than that of Precambrian craton.But in Australian the situation is different,that is the Precambrian craton has the thicker lithosphere root than Archean craton. The relationship of lithosphere thickness between craton and its adjacent orogenic belts is not clear,in North America the lithosphere thickness of craton is thicker than its adjacent Cordillera Mts orogenic belts,but in South America the lithosphere thickness of craton is shallower than its adjacent Andes orogenic belts.(3)By analysing the linear relationship of Moho depth and LAB (Lithosphere Asthenosphere Boundary)depth, We find that,for the same type of lithosphere,the Moho depth and LAB depth has a clear linear relationship,but for different type of lithosphere,the linear relationship is different.The reason for these may be associated with lithosphere forming times,its long-period tectonic environment and mantle melting process et al.
