Abstract: From 2011 to 2016, China Geological Surveyhas deployed and completed 1:250 000 geochemical data update and 1:50 000 geochemical exploration in the East Tianshan metallogenic belt, with the area of 34 843 square km and 6 200 square km respectively, it has also done the data updating of the geochemical exploration data of low availability level in Eastern Tianshan area. Thus, the 1:50 000 geochemical exploration has achieved full coverage in the middle part of EastTianshan metallogenic belt, which not only provides systematic and reliable geochemical data for mineral resources evaluation and basic geological studies, but also has found a large scale of lead-zinc ores in Aqishan, two middle scale of copper-nickel ores in Baixintan and Lubei, the small scale of lead-zinc ores in Qingbaishan, as well as some ore-finding information through carrying out the anomaly verification. The geochemical explorationhas remarkable effect,which is able to promote the mineral resources evaluation effectivelyin Eastern Tianshan area.
