B ides the tellurides mentioned above that are common in gold deposits, Te isalso seen in such rare minerals as hessite, Au2Te and, a variety of unnamed telluritesand tellurates that may be subdivided into Au-bearing and Au free minerals. Theformer includes AtteO3, Au2TeO4, AuTeO4; and the latter schieffinilite, Zn2Te3O8,H2Pb2Fe4[TeO4]9.7-12H2O that were found by the author and are yet to be furtherstudied for acceptance by IMA-CNMMN as potential new minerals.

Most of thesete1lurites and tellurates in these deposits are found to be products of coeval oxidationof calaverite, altaite and sufides, by Which "refractory gold" of Au tellurides will bereleased as naive gold. Most native gold released through oxidation of tellurides,however, will be trapped in the telluraes or tellurites; or be combined by Te intellurites or tellurates, which prevent gold of hyPergene from secondaxy enrichmentunder the supergene oxidation environrnenis.

研究表明，这些碲含氧盐大多数为碲金矿、碲铅矿与硫化物共同氧化的产物，&难溶金&矿物在氧化条件下发生分解，一般释放出自然金；由于金要么以自然金形式被&捕获&于这些含氧盐，要么重新与碲形成Au－Te含氧盐，所以抑制了金的次生富集。

It has been found that the stability is related to the substitution, the bridged methine chain and the porlarity of the dyes.
