Figure 1

Paleoenvironmental map of the South China Block in the Early Cambrian (after ref. 18, with permission from Elsevier), showing locations of investigated sections. The figure was created by the author and co-authors, with mainly MapGIS 9.0 (http://www.mapgis.com/) constraining the geographic locations and CorelDRAW × 4 (http://www.corel.com/en/) further enhancing this illustration.
