通过对萨瓦亚尔顿金（ 锑） 矿床矿石中共生石英的流体包裹体作 Ｒｂ Ｓｒ 等时线年龄（２３１ ±１０ Ｍａ） 的研究，表明成矿时代为印支期，与南天山造山带陆内造山晚阶段一致。由于矿区主体赋矿地层的（２）（３） 岩性段中无化石，故采集其中的一组无矿石英脉作包裹体 Ｒｂ Ｓｒ 等时线年龄（３８９ ±４２ Ｍａ） ，推测赋矿地层年龄上限为志留 泥盆纪。根据近年来在赋矿岩系的（１）（２） 段所发现的动物化石年代依据，指出含矿浊积岩系东部和西部二个岩性段即（１） 和（４） 段为石炭系。
By studying the Rb Sr isochron age (231 ± 10 Ma) of the fluid inclusions of the symbiotic quartz in the gold of the SAWAR gold (antimony) ore deposit, the metallogenetic age is Indo-Chinaian and coincides with the southern Tianshan orogenic belt Intracontinental orogenic phase late. Due to the absence of fossils in the (2) (3) lithology of the ore-hosting strata, a group of ore-free quartz veins were collected for inclusion Rb Sr isochron age (389 ± 42 Ma) The upper limit is Silurian Devonian. According to the data of animal fossils found in paragraph (1) (2) of the ore-bearing rock series in recent years, it is pointed out that the two lithologic segments in the eastern and western parts of the turbidite series of ore-bearing are (1) and (4) system.
