The Sibao Orogenic Belt (SOB) in South China is regarded as one of the worldwide 1300-1000 Ma mountain belts that record the assembly of the supercontinent Rodinia. However, recent work suggests that some of these mountain belts, including the SOB, were probably active until 900 Ma, thus questioning parts of the early Rodinia reconstructions. In this study we aim to determine the ages, and geochemical and structural characteristics of key tectonic units in the SOB. This will lead to a better understanding of the assembly process of Rodinia, and events occurring in continental blocks adjacent to Australia at that time.

华南四宝造山带（SOB）被认为是世界范围内记录了罗丁尼亚超大陆聚集的1300-1000马山带之一。然而，最近的研究表明，这些山带中的一些，包括SOB，可能在900 Ma之前都是活跃的，因此对早期罗迪尼亚的部分重建提出了质疑。在此基础上，确定了该区主要构造单元的年龄、地球化学特征和构造特征。这将有助于更好地理解罗迪尼亚的组装过程，以及当时澳大利亚附近大陆块体发生的事件。
