Discussion on the relationship between Chinese porphyry copper deposits and adakitic rocks. Earth Science Fr ontiers , 2007, 4( 5) : 99-2 0 Abstract: A comparative study o f the geo chemical character istics and g eochrono log ical data of 26 main por phy- ry copper deposits in China has been carr ied out . T he r esults of this w o rk indicates that 25 depo sits ar e associ- at ed w ith adakit ic ro cks especially asso ciated w ith the C- type adakit e, fo rmed by the magma der ived fr om the pa rtial melt ing of basaltic lo w er- cru st . T he ava ilable data show that the T uwu- Y andong and Pulang po rphyr y copper deposits are probably associated w ith O- ty pe adakite, for med by magmas der iv ed fro m t he partial melt- ing
