Abstract Granite–porphyries of the Yazovka complex occur in the northern part of the Riphean Baikal–Patom fold-thrust belt within the Tonod Uplift of the Early Precambrian basement. The geochronological (U–Pb), isotope-geochemical (Sm–Nd), and geochemical studies have shown that the rocks of this complex belong to A-type tin-bearing granites of the age of 709 ± 7 Ma. Initial magma of these granites was formed from the mixed Early Precambrian crustal and mantle source in the intraplate geodynamic setting. This tectonic event was global in nature and manifested the Late Riphean impulse of the lithospheric extension, which was associated with breakup of the supercontinent Rodinia under the influence of a mantle superplume.

贝加尔湖-帕托姆褶皱冲断带亚佐夫卡杂岩体含锡花岗岩的时代、来源和构造背景

摘要 Yazovka 杂岩的花岗斑岩出现在早前寒武纪基底 Tonod 隆起内的 Riphean Baikal-Patom 褶皱冲断带北部。年代学（U-Pb）、同位素地球化学（Sm-Nd）和地球化学研究表明，该复合体的岩石属于年龄为 709±7 Ma 的 A 型含锡花岗岩。这些花岗岩的初始岩浆是在板内地球动力学环境中由早前寒武纪地壳和地幔混合源形成的。这一构造事件本质上是全球性的，表现出岩石圈伸展的晚里弗期冲动，这与在地幔超羽流影响下罗迪尼亚超大陆的破裂有关。
