Abstract: Geological survey has played a prominent role in the implementation of chinese national strategies such as ore prospecting in Northwest China, development of the west region, national energy security construction, land and resources survey and ecological civilization construction. As the "eye" of geological survey, the importance of analytic technique is self-evident. First, we introduced the development of geochemical analytic technique in China and abroad, reviewed the development history of geochemical analytic technique in Northwest China, and discussed the status and main characteristics of geochemical analytic technique. We then expounded the progress of geochemical analytic technique in Northwest China in different historical periods especially in the past decade, and its application in the fields of geological survey, solid mineral resources survey, oil and gas energy geological survey, hydrogeology and groundwater pollution survey and soil ecological geochemical survey. We also discussed the needs and challenges of geochemical analytic technique in the field of strategic mineral survey, health geology, the construction of ecological civilization and the high-quality development of the Yellow River Basin in the new development stage, and finally prospected the direction and top priority of Geochemical analytic technique in the future.
