Geochemical mapping at national and continental scales continues to present challenges worldwide due to variations in geologic and geotectonic units. Use of the proper sampling media can provide rich information on the geochemical compositions of different geological units as well as geochemical responses to climate change, weathering and various types of mineralization. The abroad study on geochemical transect, is mainly for the North American continent scale geochemical transect research across Canada and the United States (Smith et al., 2008; Drew et al., 2010). However, China is still at the primary systematically studying the content and spatial distribution of geochemical elements on the national or continent scale, especially in the area of the geochemical transect. Different from the China geochemical baseline, which of study rang is a nationwide two-dimension planar, however, the study area of the geochemical transect is a national or continent one-dimension transect. The sampling density of the latter is high(1~4 km/site) along a linear sampling route to collecting regolith and rock samples, through which demonstrating the spatial distribution relationships between element content of sediments or rocks and the various factors, for example, geology, geography, climate et al. In order to study the regional geochemical composition and lateral spatial variation of the geochemical elements, a national-scale geochemical transect across the Xingmeng Orogenic Belt and the North China Craton has been completed as a part of the China Geochemical Baselines Project (Wang et al., 2015). Its purpose is to
