Metalliferous coal deposits in East Asia (Primorye of Russia and South China): A review of geodynamic controls and styles of mineralization

“…Widespread felsic volcanism of the Ust' Suyfun Formation during stage 4 is considered to have resulted from melting of the upper crust under the influence of the ascending mantle diapir (plume? ), the main source of the later within-plate basalts (Popov et al, 2007). According to their position below the flood basalts and the similar distribution of their 87 Sr/ 86 Sr and 143 Nd/ 144 Nd ratios (Fig.…”
