TL;DR: In this article, LA-ICP-MS U-Pb dating of detrital zircons suggests that the maximum depositional age of the basement sedimentary rocks in the western part of the Jiangnan orogen is ca. 860-800 ǫ.

TL;DR: Based on geochemical and petrological studies of the Meso- to Neoproterozoic basic-acid rocks, a preliminary model for the formation and evolution history of the western Jiangnan orogen in the area was put forward as discussed by the authors.

TL;DR: In this paper, a negative correlation of Th/U versus d 18 O is found for most analyses, indicating a dramatic shift toward higher oxygen isotope values by voluminous partial melting of supracrustal rocks and signaling a transition from I-type to S-type-like magmas during the later stage of magmatic evolution.

TL;DR: Mafic-ultramafic rocks from northern Guangxi show mainly calc-alkaline features as mentioned in this paper, which can not be regarded as an indicator of breakup of Rodinia supercontinent.

TL;DR: In this paper, the authors suggest that the mineralogical and geochemical differences between the aluminous and peralkaline subgroups are likely to have been generated via different differentiation paths controlled by varying fluorine contents of the parent magmas.
