【摘要】 归来庄贫硫氧化型低温热液碲金矿床中金及碲化物矿物主要有自然金、碲金矿、碲金铜矿、碲银矿、碲金银矿、碲铅矿、碲镍矿、碲汞矿及自然碲等。金元素主要来源于泰山群山草峪组的片麻岩及寒武—奥陶系海相碳酸盐岩 ;碲元素主要是由铜石杂岩体的二长质、正长质等中偏碱性岩浆从地球深部的上地幔、下地壳带入矿区并进入由岩浆水及大气降水等组成的成矿热液中 ,与金元素形成碲金络合物进行搬迁、富集 ,因成矿体系的 p H、Eh等物理化学条件及 f Te,f S2 ,f O2 等之间的关系的变化而形成了以自然金、碲及碲化物等一系列矿物为主的碲型金矿床。矿床中碲元素可加以综合开发利用。更多还原

【Abstract】 In the Guilaizhuang epithermal sulphur poor oxidation tellurium gold type deposit, the main gold and tellurium minerals are native gold, calaverite, kostovite, hessite, petzite, altaite, melonite, coloradoite, and tellurium. The Taishan group gneiss and Cambrian Ordovician marine carbonate rocks are the main source of gold while tellurium is carried by monzonite or syenitic neutral alkalic magma of Tongshi complex from deep crust (upper mantle or lower crust) to the ore deposit depth where it is involved in hydrothermal fluid as Te Au complx to be transported and enriched. Variation of pH, Eh and relations of f Te f S 2 f O 2 resulted in native gold, tellurium and telluride mineral assemblage in the deposit. Tellurium can be synthetic exploited.更多还原
