The Study On Early Bronze Metallurgy Within The Regions Of West Tianshan Mountains In Xinjiang During The 2^nd Mellenium BC

The regions of West Tianshan Mountains in Xinjiang link to Central Asia deep into the heart,the Andronovo from the Eurasian steppe impacted greatly on the regions and also amounts of early bronzes have been found here.Furthermore,a more than 3000-year-old site which was probably used for copper smelting,and this early site is the only one which we can prove that there had been a complete copper producing in the 2nd millennium BC.It’s a research project to figure out how ancient people were doing production here.In this research,we will study on the bronzes and metallurgical remains with optical microscope,scanning electronic microscope,lead isotope ratios detection and some other measures.Some problems will be discussed:where the bronzes and minerals came from,how the metallurgy changed and how the localized production went.The study shows that the decorations in quantity are the most and the styles of bronzes are simple from the sites in the first half of 2nd millennium BC.Adunchuluu cemeteries and inhabitation remains are the ones of such sites.The shapes and alloy of copper and tin are both Andronovo styles.These bronzes were probably traded,exchanged or carried into the regions.In the second half of 2nd millennium BC,the shapes of bronzes and alloys were diversified:the amount of tools and knives increased,copper-tin alloy were still being used,but also copperarsenic alloy were used,which might happen because of localized production.Ba has been detected in the slags and minerals samples from Jirentai site,which matches the characteristic that barite is the main composition of gangue mineral from the Awulale metallogenic belt,and Nulasai copper mine is in that belt.It proves that the localization production had been started..
