Abstract—

Data on the mineral, chemical, and Nd isotope composition of the highly aluminiferous schists of the Gorlyk Formation in the Tunka Bald Mountains of the Eastern Sayan Range, which are correlated with the Vendian–Cambrian sedimentary cover deposits in the central part of the Tuva–Mongolian Microcontinent, are presented. The highly aluminiferous sediments were deposited on the distal shelf of the microcontinent, and the chemical composition (high Cr, V, and Zr concentrations) of the schists of this formation indicates the acidic and basic–ultrabasic rock erosion products as their precursors. It was established that the protolith of the parametamorphic rocks was probably composed of the fragments of plutonic and volcanic rocks of the destructed Sarkhoi and Dunzhugur island arcs and the metamorphic rocks of the Gargan cratonic block, as well as the weathering crusts that developed on these rocks.

萨彦岭东部滕卡秃山的Vendian高铝质岩的起源：同位素，地球化学和矿物学证据

摘要—

东萨彦岭地区通卡秃山高戈里克组高铝片岩的矿物，化学和Nd同位素组成数据，与图瓦河中部的文迪安—寒武纪沉积盖层沉积有关介绍了蒙古微大陆。高度含铝的沉积物沉积在微洲的远端层架上，这种地层的片岩的化学成分（高Cr，V和Zr浓度）表明它们是酸性和碱性-超碱性岩石侵蚀产物。已经确定，准变质岩的原石可能是由萨尔霍伊岛和敦朱古尔岛弧破坏的火山岩和火山岩碎片以及加尔甘克拉通块体的变质岩组成，
