文摘
- •
Voluminous Mesoproterozoic continental arc magmatism occurred from at least 1.45 to 1.40 Ga in the CTA;
- •
Widespread Mesoproterozoic crustal growth was associated with the continental arc magmatism in the CTA;
- •
The Mesoproterozoic CTA underwent multiple reworking and metamorphic events in the Neoproterozoic and the Paleozoic;
- •
A Precambrian correlation of the CTA and the Tarim Craton is questionable;
- •
The CTA and the southern Beishan microcontinents underwent a similar Precambrian tectonothermal evolution.
