陕西驾鹿金矿床首次发现的40种含氧金矿物,呈褐、紫、黑等不同色调,多为不规则粒状及微细晶集合体,粒径0.01~0.5mm;条痕紫、黑色、半金属光泽,不透明;反射多色性显著;摩氏硬度2~3.这40种含氧金矿物主体与黄铁矿、碲金矿和石英共生,属于内生热液成因.依据金的地球化学行为,以及区内含氧金矿物富含Te(10%~20%)和不等量Mn的特征,认为该矿床成矿元素(Au)主要是在碲酸及硫酸溶液中,在有氧化剂MnO2存在的条件下迁移富集成矿.通过细致的电子探针分析,初步确定了驾鹿金矿床中16个类型40种含氧金矿物,主要成分为Au、Pb、Fe、Te和O.这些矿物在主要成分上虽与前苏联发现的别斯麦特矿、毕利宾矿、博格丹诺夫矿以及我国东坪金矿床发现的金的碲酸盐矿物有类似之处,但因其普遍含不等的Mn、Ca或Al、As、Co、Ni等而又有所不同,因此很可能是一系列新的矿物种或新(亚)种金矿物.X-射线衍射分析表明,大部分晶体结构可能是由Au、Ag、Cu、Fe或Pb等金属互化物组成的假立方晶格与一个由β-TeO2(可能包括PbO或CaO)组成的斜方晶格的混晶,但不排除它们是含金氧化物的可能性.还有些可能是玻璃质或纳米级矿物,少部分则呈现准晶态物质的特征.
40 kinds of oxygen-bearing gold minerals first discovered in the area of the Qin’er gold deposit in Shaanxi Province are brown, purple and black with different shades, mostly irregular granular and fine-grained aggregates with grain sizes of 0.01-0.5 mm. Streaks purple, black and half Metallic luster, opaque, remarkable reflectivity, and Mohs hardness of 2 to 3. The 40 oxygen-bearing gold minerals coexist with pyrite, tellurium and quartz, and belong to the genesis of endogenous hydrothermals.According to the geochemistry of gold Behavior and the characteristics of Te (10% ~ 20%) and unequal Mn in the oxygen-bearing gold minerals in this area. It is believed that the ore-forming elements (Au) in this deposit are mainly in the telluric acid and sulfuric acid solution, In the presence of migration and enrichment of mineralization.A detailed electronic probe analysis, initially identified in the deer gold deposit 16 types of 40 kinds of oxygen-bearing gold minerals, the main components of Au, Pb, Fe, Te and O. These minerals Although the main components are similar to those found in the former Soviet Union at the Besite mine, the Pilipin mine, the Bogdanov mine and the gold tellurite minerals found in the Dongping gold deposit in our country, , Mn, Ca, Al, As, Co, Ni, etc., it is likely to be a series of new mineral species or new X-ray diffraction analysis of minerals shows that most of the crystal structure may be pseudocubic lattices composed of intermetallic compounds such as Au, Ag, Cu, Fe or Pb and a pseudo-cubic lattice composed of β-TeO2 (possibly including PbO or CaO) Rhombohedral lattices but does not rule out the possibility that they are gold-containing oxides, some may be vitreous or nanoscale minerals, and a small proportion of them exhibit the characteristics of quasicrystalline materials.
