Those were indeed the olden days so the only " active " element was a galena crystal grazed by a wire whisker 那确实发生在过去的岁月，所以，我唯一的“行动”是利用金属须晶轻轻擦过硫化铅晶体。
The results indicated that large amounts of non - natural silver grains existed in this branch of lead concentrates and the silver grains were distributed around the galena in a loose flocculating form 结果表明，此批铅精矿含有大量的非天然银矿物，银颗粒呈疏松絮状物分布在方铅矿周围。
< uk > the minerals are likely to be from the suite pyrite chalcopyrite , sphalerite , galena , fluorite and barite , and to be deposited at temperatures of between 50 and 250 . < / uk > 这些矿物可能由黄铁矿，黄铜矿，闪锌矿，方铅矿，萤石和重晶石组成，并且可能是在50 250之间的温度下沉积出来的。
The main metals mineral are chalcopyrite , the next clinohedrite , alpha chalcocite bornite , malachite and azurite . a little amount blende , galena incidentally ryby silver , bismuth 矿石中主要金属矿物为黄铜矿、其次为黝铜矿、兰辉铜矿、斑铜矿及铜的氧化物孔雀石、蓝铜矿。闪锌矿、方铅矿少量，偶见淡红银矿、硫酸钮矿。
And some fabulous new samples of green fluorite on sphalerite and galena from naica , mexico , which were collected some time this year - here evan is holding one of the best examples of this new find 还有一些新标本的如来自于墨西哥奈卡的闪锌矿和方铅矿上共生绿色萤石，这是今年的热门收藏，埃文在此次展会上最好的一批中淘到了一个。
Cd chiefly occurs in sphalerite with moderate to light colors , while ga and ge are mainly enriched in galena . predominant amounts of the dispersed elements occur at the middle and late stages of the hydrothermal ore - forming epoch Cd主要赋存在浅色和中色闪锌矿中，而ga 、 ge主要赋存在方铅矿中，分散元素在热液成矿期的中、晚阶段大量富集。
