康捷尔碱性-超基性岩体的铂族元素矿物主要是等轴铁铂矿,该矿物有两个世代,即:①早期高温等轴铁铂矿,形成于纯橄榄岩中;②晚期世代等轴铁铂矿,多充填于纯橄榄岩致密块状铬铁矿透镜体或脉体的间隙中,有时呈立方体结晶分布于纯橄榄岩内金云母-磁铁矿单斜辉石岩岩墙或脉体中.高温等轴铁铂矿与晚期世代等轴铁铂矿的含铁性相近(ωFe7.5%~11.5%),其差别在于高温等轴铁铂矿含铂族元素较高(ω),Ir5.3%、Os2.9%、Rh1.8%,而晚期等轴铁铂矿一般Ir不超过1.9%、Os1.0%、Rh0.6%.铂族元素的次要矿物有两类:①形成于岩浆期的矿物,如Os-Ir-Ru-Pt系的固溶体矿物(包括自然铂、自然锇,自然铱、自然钌);②岩浆后期矿物,如四方铁铂矿,四方铜铁铂矿、洪戈石、二硫锇矿-二硫钌矿、硫砷铱矿-硫砷铑矿、硫铂矿,铋化物,锑化物,碲化物,锡化物及氢氧化物等一系列新矿物(Pd-洪戈石、Rh-兴中矿,Pt-康捷尔矿,硫铱铅铜矿等).上述矿物在等轴铁铂矿颗粒的周围或边部多形成镶边.类似的产状亦见于低温等轴铁铂矿之周围,并形成有自然金,含银自然金至金银矿、银金矿等.此外,还见有含铜、含铜-铅、含铜-钯的自然金,其组成为?
The PGM minerals of the Antarctic alkaline-ultramafic rocks are mainly equiaxed iron-platinum deposits, which have two generations, namely: ① early high-temperature equiaxed iron-platinum ore formed in the dunites; ② The late generation equiaxed iron-platinum deposits are mostly filled in the dense chrome ore bodies of the solid peridotite or in the spaces between the veins, sometimes with cubic crystals distributed in the dunite within the phlogopite-magnetite clinopyroxene rock Wall or veins. The high-temperature equiaxed iron-platinum deposit is similar in iron content to the late-generation equiaxed iron-platinum deposit (ωFe7.5% ~ 11.5%). The difference lies in the high (ω) Ir5.3%, Os2.9%, Rh1.8%, while the late equiaxed iron-platinum ore Ir generally does not exceed 1.9%, Os1.0%, Rh0.6%. There are two types of secondary elements of the PGMs: 形 minerals formed in the magmatic stage, such as Os-Ir-Ru-Pt solid solution minerals (including natural platinum, natural osmium, natural iridium, and natural ruthenium) Such as Sifang iron-platinum ore, tetragonal copper-iron-platinum ore, Hong Geshi, dithiium osmium ore - dithiocarbamate ore, sulfur arsenic iridium ore - sulfur arsenic rhodium ore, sulfur platinum ore, bismuth, antimonide, telluride, Tin and hydroxides and a series of new minerals (Pd-Hong Ge Shi, Rh-Xingzhong mine, Pt-Kangtell mine, sulfur iridium lead and copper, etc.). The above minerals are more or less edge-shaped equiaxed iron and platinum particles formed edge. Similar occurrences are found in the vicinity of low temperature equiaxed iron and platinum ore, and the formation of a natural gold, silver natural gold to gold and silver, silver and gold and so on. In addition, also see the copper, copper - lead, copper - palladium natural gold, its composition?
