Shaanxi In Different Parts Of The Soil Burial Environment And Bronze Corrosion Characteristics

China is well known in the world for its many ancient bronzes. The study on bronzes is always an important task and field in Bronze Age archaeology. However, the traditional scientific research on its provenance, age, manufacture technology and identification is far behind developed countries. As the same reason, now many shams congest the bronze market, lots of people and few of museums are caught with chaff for the shams, we must built a new appraisal system. Thus, it is an imperative task for us to systematically study the chemical composition, microstructure and physical properties of the bronzes of the typical areas in China.Another important means of study on provenance of bronzes in archarology site is trace element method. The 39 samples of the six areas were anaylzed for about 53 elements by Inductively Coupled Plasma-Mass spectrograph (ICP-MS) or Laser-Inductively Coupled Plasma Mass spectrograph (LA-ICPMS). In addition, the samples were analyzed by X-ray (XRD), scanning electronic and X-ray energy dispersive spectrometer (SEM-EDS) for the chemical composition of the bronze alloy. Lanthanide (REE pattern) between the bronze alloy, rusty of various bronze, formed by corrosion, and soil near the bronzes, were similared to each other. This can help people to authenticate the areas of the bronze's archarology site.
