摘　　要：位于东昆仑拉陵灶火河中游的含钼花岗岩体,具有典型的岩浆成因特征。通过锆石U-Pb测年,获得其形成年龄为228.49±0.84Ma,属印支期。测年结果为研究东昆仑造山带的成矿期提供了重要的年代学资料,并对其地质意义进行了讨论。认为与拉陵灶火中游花岗岩有关的铁、铜、钼多金属的主要成矿期也应为印支期。因此今后该区的区域找矿方向,应该重点放在与印支期花岗岩岩株有关的铁、铜、钼多金属矿床。This article mainly describes the Lalingzaohuo with iron,copper,molybdenum polymetallic deposit is closely related So the granodiorite rock petrochemistry, geochemistry and isotopic characteristics, and its geological significance are discussed, gesearch shows thaS, Lalingzaohuo She mausoleum in granite body has advanced fire orogenic granitoid rocks and geochemical characteristics, its formation age for 228.49 ＋ 0.84Ma. belongs to the indosinian. According to Lalingzaohuo dating results, we think and Lalingzaohuo kitchen granite related iron,copper,molybdenum poiymetallic metallogenic period should be for the Indosinian period. Therefore the future of the regional prospecting direction, should focus on finding and Indosinian granite rock strain associated wish iron, copper, molybdenum polymetallic deposis.
