| 英文摘要 | The latest achievements on bimodal volcanic rocks are reviewed in this paper. It is suggested that bimodal volcanic rocks can occur in highly contrasting geodynamic environments, such as continental rifts, oceanic islands, continental-breakup setting, incipient back-are spreading, post-orogenic extensional setting, intra-oceanic arcs and mature islands/active continental margins, etc. Rhyolites can be mainly generated in two ways. First, coeval basalts and rhyolites may share a common mantle-derived parent, while the rhyolites are evolved from basaltic magmas with a small rhyolite/basalt volume ratio, and both of them have similar geochemical characteristics. Alternatively, rhyolites and basalts may have totally unrelated sources, the rhyolite are derived from anatexis of the crust. The exposed rhyolite is predominant relative to basalt and the rhyolite and basalt often have dinstinctive geochemical characteristics. |
