This paper introduces the efficient geochemical mapping project that was proposed by Prof. XIE Xuejin in 1990s and shows its resulting maps of element distribution. It used water chemical sampling and analysis to obtained 66 geochemical quantities. This method enjoys efficient and fact mapping process, but with lower spatial resolution comparing to the deep soil sampling. The resulting maps in Xizang(Tibet) show some regularity of elements distribution, as 2/3 maps have anomalies located along the Yarlung River Suture . The reason of this elements distribution patterns involved with closing of the Tethys Ocean that contained some rich elements and left along the Yarlung River Suture, causing highcontents of K2O and Na2O. On the other hand, it also caused lowcontent of CaO, due to the carbonate deposition in the Tethys Ocean . The resulting maps in Xizang(Tibet) may have significant also for mineral exploration as well as environmental and ecology studies.
