| contents | Basaltic samples of the Woniusi rock assocation were collected from the northern, middle, and southern parts of the Baoshan block. Basaltic samples were selected for whole-rock major- and trace element analyses using X-ray fluorescence spectrometry (XRF) and inductively coupled plasma-mass spectrometry (ICP-MS). The international standards BHOV-2 (basalt), AGV-2 (andesite), and W-2 (dolerite) were used to monitor the data quality of major and trace elements concentrations. 87 Sr/ 86 Sr and 143 Nd/ 144 Nd isotopic analyses using multi-collector (MC)-ICP-MS. The87 Sr/86 Sr and143 Nd/144 Nd ratios of AGV-2 and BCR-2 (basalt) standards are in good agreement with the recommended values (Supplementary Table S5). Zircon U – Pb and Lu – Hf isotopic analyses were performed on two representative samples using laser ablation (LA)-ICP-MS and LA-MC-ICP-MS, respectively. The zircon Plesovice are dated as unknown samples and yielded a weighted mean 206 238 Pb/ U age of 337 ± 3 Ma238 (2σ, n = 40), which is in good agreement with the recommended 206 Pb/ U age of 337.13 ± 0.37 Ma (2σ; Slama et al., 2008). |
