(A) Plots of paleolatitudes for the Zhongba microterrane and its surrounding terranes (South and North China blocks, North Qiangtang terrane, and Indochina terrane) and India during the Silurian to Carboniferous. Red dot indicates the result of this study. The horizontal and vertical lines represent the stratigraphic age and the error of paleolatitude, respectively. The reference point is 29.9°N, 83.9°E. The data are stored in the Supplemental Material (see text footnote 1). (B) Equal-area projection of the late Paleozoic paleomagnetic poles of the Zhongba microterrane and surrounding terranes and the paleomagnetic pole of India during 400–360 Ma. Red dot and associated ellipse represent the paleomagnetic pole and confidence interval of the Zhongba microterrane (ZM). The blue dots represent the paleomagnetic poles of India at different times. The other colored dots represent the paleomagnetic poles of the terranes surrounding the Zhongba microterrane. The paleomagnetic poles represented by the numbers can be seen in the Supplemental Material (Table S4 [see text footnote 1]).
