The provenance of the highly radiogenic lead (HRL) contained in Chinese Shang bronzes has attracted great scholarly attention in recent years. A new study of the Hanzhong Shang bronzes has put forward a hypothesis that the HRL metal may come from the adjacent Qinling Mountains. This article reanalyses the lead isotope ratios and alloy compositions of the Hanzhong bronzes. Combining the analytical results, the modern ore data and the slags from Guanzhong area, we propose that there is no direct evidence to identify Qinling as the provenance of HRL metal (especially lead). Whilst over 80% of the Hanzhong bronzes contain HRL, the indigenous artefacts containing both HRL and special alloying elements (As, Sb, Ni) account only for minor portions. This fact cannot verify that HRL originates from Qinling, and even makes it difficult to prove that most of the Hanzhong bronzes use local metal resources. An alternative argument might be that the HRL used in Hanzhong derived from the Shang dynasty. The use of HRL reflects a unified system for allocating metal resources centred on the Shang kingdom, which has great significance for further understanding of the resource circulation patterns among different bronze cultures and locations during the Shang period.
