Located in the Qimantage area, Qinghai Province, the Hutouya is a typical skarn-type lead-zinc polymetallic ore district consisting of contact and exocontact substyles, relationship with Indosinian intrusive rocks. In this ore district, a plurality of containing carbonate stratum outcropped in different ages. Ore-forming metal element combinations were complicated. Occurrences of intermediate-acidic intrusive rocks were changeable and lithology were diversiform. But ore-forming rock bodies and abilities restricted perambulation of ore districts and areas. This thesis are based on field geological investigation, we studies rock body thermochronology and rock geochemistry. The LA-MC-ICP-MS U-Pb dating of zircon from adamellite yield ages of 230.3±3.7 Ma (n=13, MSWD=1.4) of Sample HTY016. And 40Ar-39Ar dating yield plateau ages of 229.6±2.3 Ma from biotite and 219.3±1.8 Ma from plagioclase. The petrogenic age is Indosinian. The rock body condensing rate of different minerals from adamellite shows that the adamellite in Hutouya is rather quick and the thermal effect is much larger, so the metallogenic potential much larger. The adamellite is high-K calc-alkaline series and resulted from deep penetration or deep penetration of antique crust joined with mantle materials.
