摘要: 2011~2016年中国地质调查局先后在东天山成矿带部署完成1：25万区域化探数据更新34 843 km2、1：5万化探6 200 km2，完成了部分区域化探资料可利用程度较低图幅的数据更新，实现了东天山成矿带中段1：5万化探的全面覆盖，不仅为矿产资源评价和基础地质研究提供了系统可靠的地球化学资料，异常查证中还发现了阿齐山大型铅锌矿、白鑫滩与路北2个中型铜镍矿和清白山小型铅锌矿及一批矿产信息，地球化学勘查效果显著，找矿成果丰硕，有力促进了东天山地区矿产资源调查评价工作。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.
