对采自Faulty Towers(47°57.447′N,129°6.568′W)硫化物烟囱群一个不再活动的烟囱体硫化物开展了详细的矿物学和地球化学研究。样品从外壁往内壁方向可划分为4个矿物组合带,分别为重晶石-无定形硅-铁氧羟化物带;白铁矿-黄铁矿-无定形硅-重晶石带;白铁矿-黄铁矿-闪锌矿-纤锌矿带;纤锌矿-黄铜矿-白铁矿带。从底部到顶部,样品通道形态主要有3种:不规则、不连续的多通道;椭圆形单通道;封闭的通道。矿物学研究证实,烟囱体以低温矿物组合白铁矿、纤锌矿为主,高温矿物黄铜矿少见,仅局限分布在流体通道附近。210 Pb定年结果表明,烟囱壁形成经历较短时间(约3a),而通道的闭合则经历了相对长的过程(约17a)。结合矿物学研究,最终恢复了整个尖塔结构的生长历史。
A detailed mineralogical and geochemical study was conducted on an inactive chimney body sulfide from the Faulty Towers (47 ° 57.447’N, 129 ° 6.568’W) sulfide stack. Samples from the outer wall to the inner wall can be divided into four mineral assemblages, respectively, barite - amorphous silicon - hydroxylamine belt; white iron ore - pyrite - amorphous silicon - barite belt; white iron Ore - pyrite - sphalerite - wurtzite belt; wurtzite - chalcopyrite - marcasite belt. From the bottom to the top, there are three main sample channel shapes: irregular, discontinuous multi-channel; oval single channel; closed channel. Mineralogy studies have confirmed that the chimney body with low-temperature mineral combination of white iron ore, wurtzite-based, high-temperature mineral chalcopyrite rare, limited distribution in the fluid channel near. The results of the 210 Pb dating show that the chimney wall has been formed for a relatively short time (about 3a), while the closure of the channel has undergone a relatively long process (about 17 years). Combined with mineralogy research, the final restoration of the entire minaret structure of the growth history.
