一、早太古代火山成因岩石组合在科拉半岛,具清晰的残余喷出构造的早太古界岩石分布比较少,首先描述了潘斯-通得地区以北的中科拉背斜区的火山岩组合(1968),在那里,大部分太古界喷出岩都被改造成各种类型的片麻岩、角闪岩和混合岩。这些岩石相当于白海群和科拉群的下部(赫士拉姆比,克烈特组部分),在中科拉背斜和沃罗尼亚河地区,早太古代变质喷出岩呈残余状和捕虏体,分布在太古代花岗闪长岩和斜长花岗岩中,并被花岗闪长岩侵入,具典型的侵入接触特点。
First, the Early Archean volcanic origin rock assemblage in the Kola Peninsula, with a clear remnants of the discharge structure of Early Archean rocks are relatively small, first described the Pans - Tongde area north of the Cora anticlinal volcanic rocks (1968), where most of the Archean expelled rocks have been transformed into various types of gneiss, amphibolite and migmatite. These rocks are equivalent to the lower part of the Baihai Group and the Corra Group (Heshamumby, Crete Formation). In the Nakola anticline and the Voronoi region, the Early Archean metamorphic exuded rock was remnant and Xenoliths, distributed in the Archean granodiorite and plagiogranite, were intrusive by granodiorite and characterized by typical intrusion.
