| Abstract: | The Precambrian volcanic rocks in Hunan includes:Mesoproterozore island arc tholeiites of active continental margin(initial); neoproterozoic rifting alkaline basalt(subvolcanic rock)of passive eontinental mar-gin; and the tholeiite-calcalkaline-alkaline volcanic rock suit of active continental margin(mature island arc),of which the basic rocks constituted flysch-like thrust segment that marks the boundary of terranes. |
