| Abstract: | The distribution and time span of the early Palaeozoic marine volcanic rocks from north-ern Qinling are briefly reviewed in the present paper.The sequence and conmposition of thevolcanic rocks are discussed.The series,types,nomenclature and association of the volcanicrocks are determined.The tectonic settings and their evolution processes of the volcanic rocksare studied.The distance,time and velocity of the open-closing processes are estimated.Thecompositions and origins of the primitive magmas,the depths of magma chambers and thetypes of mantle are probed into. The temperatures and sequences of crystallization of magmaare examined. |
