Figure 1: Geological map of Yangkou bay and General's Hill.
From: Partial melting of deeply subducted eclogite from the Sulu orogen in China
(a) Simplified geological map of the Sulu orogen and its location in China. Scale bar, 100 km at 50-km intervals. (b) Geological map of Mt. Laoshan and the structural setting of Yangkou Bay and General's Hill35. Scale bar, 1 km at 0.5 km intervals. (c) Map of continuously exposed coastal outcrops at General's Hill. Scale bar, 30 m at 15–m intervals. Our detailed 1:1,500 scale mapping delineates strongly foliated and complexly folded retrogressed eclogite, cut by channels of dominantly felsic leucosome. The most weakly retrogressed part of the eclogite body consists of strongly foliated isoclinally folded eclogitic gneiss, interlayered with foliated felsic leucosome and retrogressed eclogite (now garnet-bearing amphibolite). In other places the eclogite is preserved as sheared boudins with leucosome and quartz veins in pressure shadows of the eclogitic boudins. Mapping by L. Wang, T. Kusky, S. J. Wang, J. P. Wang and Y. Ding.
