  • Arguments persist on the genesis and ages for the banded-augen (rapakivi) anatectic granitoids (charnockite) extensively outcropped in the Yunkai (云开) region, western Guangdong (广东) Province. Their petrochemistry, SHRIMP dating, deformational and metamorphic structure were studied. The results show that most granitoids are A/CNK > 1.1, CaO /Na2O = 0.62-1.61 (average 0.94 > 0.3), Al2O3/TiO2 = 16.6-60.6 (average 23.68), depleted high field strong elements Ta, Nb, Zr, strong peraluminous high-K calcalkaline and calcalkaline granitoids in the post-collisional tectonic environment of a subduction-collision orogenic belt in an active-continental margin. The temperatures of charnockite and gneissic garnet-bearing biotite monzonitic granite are obviously higher than those of banded-augen (rapakivi) biotite monzonitic granite, and charnockite and gneissic garnet-bearing biotite monzonitic granite with the evolutional characteristics of A-type granites. The forming ages from banded-augen (rapakivi) biotite monzonitic granite to charnockite and gneissic garnet-bearing biotite monzonitic granite, whose crystallizing zircon SHRIMP ages are (465 ± 10) Ma, (467 ± 10) Ma, (435 ± 11) Ma and (413 ± 8) Ma, respectively, become younger. This shows that there was an oceaniccontinental subduction-collision and post-collisional extension-delamination-underplating between the Yangtze and Cathaysia plates during the Caledonian, and the granitoids experienced compressional uplift and extensional exhumation during the Indosinian. This provides important evidence of subduction collision of the Yangtze plate to the Cathaysia plate during the Caledonian in South China.
