Yanjiagou Cemetery, located on the boundary of Guanzhong area and northern Shaanxi, features several complicated cultural factors. For the first time, twelve bronze containers unearthed from Yanjiagou Cemetery were analyzed to determine compositions and metallographic structures. The results show that five pieces of the twelve bronze wares were made of red copper, four made of lead-arsenic bronze, two made of arsenic bronze and one made of lead bronze. The twelve bronzes were cast and some bronzes were heat-treated. According to a literature review, the “no tin, high lead and high arsenic” materials of the bronze wares unearthed from Yanjiagou Cemetery are different from those from the Central Plains and northern China. Its own heavy food tradition is very different from other Lijiaya cultural sites in northern Shaanxi, which shows that its own cultural traditions still dominate in some respects at Yanjiagou area. However, special as this phenomenon is, it is still a member of Lijiaya Cultural Sites. The analysis results could provide a reference for the study of the cultural exchange between Guanzhong area and northern Shaanxi during the late Shang Dynasty.
