本文主要研究内容
作者秦克章,周起凤,唐冬梅,王春龙（2019）在《东秦岭稀有金属伟晶岩的类型、内部结构、矿化及远景——兼与阿尔泰地区对比》一文中研究指出：东秦岭地区和阿尔泰造山带均产出大量稀有金属伟晶岩,是中国重要的稀有金属产地。前者工作程度低,远景尚不明朗;后者规模巨大。开展成矿条件对比研究十分必要。东秦岭地区产出铍矿、锂矿和复杂稀有金属矿,以锂矿化为主,伟晶岩类型复杂,包括绿柱石-铌铁矿型、复杂型锂辉石亚型、复杂型锂云母亚型和钠长石-锂辉石型。阿尔泰稀有金属伟晶岩发育多种稀有金属矿化组合,伟晶岩类型为绿柱石-铌铁矿型、复杂型锂辉石亚型和钠长石-锂辉石型。东秦岭稀有金属伟晶岩的内部结构分带型式包括对称分带结构、均一结构和分层结构,阿尔泰稀有金属伟晶岩以对称分带结构为主,也见均一结构。东秦岭与阿尔泰稀有金属矿石矿物相近,东秦岭产出更多含锂磷酸盐矿物。东秦岭稀有金属伟晶岩分异演化程度相对集中且高,阿尔泰稀有金属伟晶岩分异演化程度跨度大。东秦岭和阿尔泰锂矿的锂矿化主要发生于岩浆就位前,复杂稀有金属矿稀有金属富集作用发生在岩浆就位前和就位后,但阿尔泰复杂稀有金属矿经历了更为复杂和极度的分异演化过程。东秦岭稀有金属伟晶岩可能与同期花岗岩为同一熔融事件的产物,与早期花岗岩来自同一物质来源。阿尔泰稀有金属伟晶岩与花岗岩关系复杂,但大量早期花岗岩的形成提高了地壳成熟度,有利于形成晚期稀有金属伟晶岩。东秦岭稀有金属伟晶岩产出于北秦岭单元中,形成于晚造山和造山后阶段,集中于造山后阶段,稀有金属矿化呈多期断续叠加特征。阿尔泰稀有金属伟晶岩主要产出于琼库尔-阿巴宫地体和中阿尔泰山地体内,集中于造山后和非造山阶段。伟晶岩岩浆活动受控于物质来源和造山作用。储存稀有金属的岩石在造山作用中熔融,发生多期的大规模花岗质岩浆活动,稀有金属通过长期复杂的分异演化过程在残余熔体中不断富集。这种富挥发分和稀有金属的过铝质硅酸盐岩浆随后上升就位,可经后续冷却结晶和不混溶作用进一步富集稀有金属,从而形成稀有金属伟晶岩。东秦岭具有形成含稀有金属高度分异演化岩浆的有利条件,该区具有寻找铍矿和复杂稀有金属矿的潜力。
