补充资料:成矿分带
成矿分带 metallogenic zone 在含矿流体的活动过程中,由于地质因素和物理化学条件的变化,导致不同的矿石依次产出,形成不同矿石组合的带状分布。例如,在沉积铁矿床中,常表现出不同的矿石相沿沉积当时的海岸作带状分布,距岸由近到远的成矿分带为:①氧化物带(赤铁矿);②硅酸盐带(鲕绿泥石);③碳酸盐带(菱铁矿);④硫化物带(黄铁矿)。又如在气化热液矿床中,含矿气液随着离热源距离的增大,以及物理化学条件的变化,不同矿物的沉淀常依次成带状。例如,中国湖南柿竹园矿床中,自含矿花岗岩体向外,或由深处向浅处,可分出钨带→锡带→铋带→铜带→锌带→铅带。 成矿分带按其空间产出情况,有水平分带和垂直分带;按其规模大小,有区域成矿分带、矿床分带和矿体分带。区域成矿分带受多种因素控制,如中国江西南部为钨矿带,北部为铜(金)矿带,这是因为两地的构造背景、岩浆岩类型及变质岩基底等有明显差异造成的。 成矿分带反映了成矿作用在空间上的变化规律,查明这种带状分布规律,对指导矿产勘查和矿山开发均有实际意义。 |
