摘要：

Reconstruction of pressure-temperature-time (P-T-t) path of volumetrically-dominant orthogneisses in deeply subducted continental crusts is challenging due to their simple amphibolite-facies mineral assemblages. To provide new insights into this issue, a detailed study of mineral inclusions, trace elements and U-Pb ages within robust zircon containers, together with titanite U-Pb dating and petrology were conducted on ultrahigh-pressure (UHP) orthogneisses from the northern Sulu belt. The following P-T-t conditions of three metamorphic stages were constrained: (i) cathodoluminescence (CL)-grey...
