An open research platform integrating Pb isotope ratios, bulk-composition analyses (36 elements), and geological ore reference data for Chinese bronzes and other metal artifacts — Neolithic through Imperial periods.
Lead isotope ratios (206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb + derived) from published studies on Chinese bronze artifacts, coins, ceramics, and other metals.
Concentrations of Cu, Sn, Pb, Fe, Zn, As, Sb, Ni, Ag and 27 more elements in weight %. Detection-limit flags preserved; multiple analytical methods supported.
Pb isotope analyses of galena, K-feldspar and sulfide minerals from Chinese ore deposits (Hsu & Sabatini 2019). 16 metallogenic provinces across all major tectonic terranes.
Archaeological sites with province, period, and coordinates, plus the published sources linked to every sample in the database.
Filter by site, province, period, reference, or any combination. Multi-select supported for both Pb and TE data.
Pb scatter with KDE margins and ore overlay; TE plots with any X/Y element pair, log/linear axes, and custom data paste.
Read access needs no key. Writes require an X-API-Key: bulk-upload endpoints for Pb and TE samples, and reference creation.
Team members add data via the pbisodb-client skill — HTTPS only, no server access needed.
