Abstract:

The southern edge of Qaidam Basin gold metallogenic belt is located on the southern edge of Qaidam Basin.It contains two tectonic unites，such as Qimantag-Doulan back-arc residual basin at Early Paleozoic  (north Kunlun peak) and prepeak arc (middle Kunlun peak).The folds and faults in this gold metallogenic belt are developed.Northern Kunlun fault acrosses the mid-west part of the belt.Mid-Kunlun fault is the boundary fault of the south of Qaidam Basin gold metallogenic belt. Northern Kunlun fault and Mid-Kunlun fault make up the first order tecnonic of the belt，and it controls the stratum，magmatism，the forming and distribution of regional mineral resources.

Key words: Southern edge of Qaidam Basin, Gold metallogenic belt, Structural ore-controlling, Ore-forming age, Metallogenic regularity, Qinghai Province
