阿勒泰造山带（AOB）位于中亚造山带（CAOB）中部，是我国最重要的成矿带之一。康布铁堡组是一个晚古生代地层单元，蕴藏着许多重要的铁矿和铅锌矿床。康布铁堡组由夹层火山岩和沉积岩组成，经历了区域性绿片岩到下角闪岩相变质作用，主要出露于麦子盆地、巴朗盆地和冲呼尔盆地等三个北西向断层火山沉积盆地中。康布铁堡组三块变冰晶岩锆石的SHRIMP分析。巴生盆地的206Pb/238U加权平均年龄分别为412.6±3.5 Ma、408.7±5.3 Ma和406.7±4.3 Ma，可以解释为巴生盆地康布铁堡硅质火山岩的喷发年龄。这些年龄表明康布铁堡组形成于晚志留世至早泥盆世。他们还证明，康布铁堡组中的矿床是在 412-407 Ma 之后形成的。它们对于了解中国AOB南缘古生代构造演化和成矿作用具有重要作用。
The Altay orogenic belt (AOB), situated in the middle part of the Central Asian Orogenic Belt (CAOB), is one of the most important metallogenic belts in China. The Kangbutiebao Formation is a Late Paleozoic stratigraphic unit that hosts many important iron and Pb–Zn deposits. The Kangbutiebao Formation consists of intercalated volcanic and sedimentary rocks that have undergone regional greenschist to lower amphibolite facies metamorphism, and mainly outcrops in three NW-trending fault-bounded volcano–sedimentary basins, including the Maizi, Kelang, and Chonghuer basins. SHRIMP analyses of zircons from three metarhyolites of the Kangbutiebao Fm. in the Kelang Basin yield weighted mean206Pb/238U ages of 412.6±3.5 Ma, 408.7±5.3 Ma and 406.7±4.3 Ma, respectively, which can be interpreted as the eruption age of the Kangbutiebao silicic volcanic rocks in the Kelang Basin. These ages indicate that the Kangbutiebao Formation was formed during the Late Silurian to Early Devonian. They also demonstrate that the deposits hosted in the Kangbutiebao Formation were formed after 412–407 Ma. They play a key role in understanding the Paleozoic tectonic evolution and metallogenesis of the southern margin of the Chinese AOB.
