在蛇绿岩组合中,辉长岩类建造的岩石,以有最高的金含量为特征:由超基性岩中的3.3×10~(-7)%增到本类岩石中的4×10~(-7)%。基性和超基性岩中金的载体矿物为辉石、橄榄石、斜长石,其金含量为(1.3—4.1)×10~(-7)%,而富金的矿物——钛磁铁矿、铬铁矿、磁铁矿、钛铁矿,其含金量为(11.7—88.1)×10~(-7)%。在与阿尔卑斯型超基性岩共生的辉长岩类中,相对低的金富集,是受无亏损地幔局部熔融面上原始基性熔体中的金含量制约的。层状系列辉长岩类中富含一定数量的金,与地幔物质演化过程中岩浆熔体的分异有关。金的分布及含量逐步减少的趋势,与超基性岩的塑性变形加剧有关。金的实质性的带出,与超基性岩的交代橄榄石化有关。与蛇绿岩带内造山期花岗岩类侵入有关的辉长岩类化超基性岩和交代岩(角闪石岩、滑石菱镁片岩),它们的金含量由于该金属的重新配置和随岩浆流体的带入而增加4—9倍。
In the ophiolite assemblage, the gabbro-type rocks are characterized by the highest gold content: increased from 3.3 × 10 -7% in ultrabasic rocks to 4 × 10 in this type of rock ~ (-7)%. The basic and ultrabasic rocks of gold are pyroxene, olivine and plagioclase. Their gold content is (1.3-4.1) × 10 -7%, while the gold-rich minerals - titanium magnetic Iron ore, chromite, magnetite, ilmenite, the gold content of (11.7-88.1) × 10 ~ (-7)%. In the gabbro coexisting with alpine ultramafic rocks, the relatively low gold enrichment is governed by the gold content of the primary base melt on the local melting surface of the loss-free mantle. Lamellar series of gabbro are rich in a certain amount of gold, which is related to the differentiation of magma in the evolution of mantle material. The trend of decreasing distribution and content of gold is related to the aggravating plastic deformation of ultramafic rocks. The substantial withdrawal of gold is related to the peridotization of the ultrabasic rocks. Gabbro-type ultramafic rocks and metasomatites (amphibolites, talc magnesite schist) associated with intrusive granitic intrusions within the ophiolite belt, whose gold content due to the rearrangement of the metal and associated with magma Fluid into the increase 4-9 times.
