The crystallization temperature and pressure of clinopyroxene phenocrysts from the ankaramite and basalt were estimated on the basis of the clinopyroxene-melt equilibrium principle: 1345~1366℃ and 1.75~2.05Gpa for ankaramite, with average geothermal gradient of 20-24℃/km, suggesting anomalous heat or geothermal gradient in this region may be one of the key reasons to produce the porphyry copper deposits in the region. In contrast, those in the basalts fomed under a relatively low crystallization temperature (1129~1191℃), and the pressure (1.19~1.60Gpa) and depth (39~53km), suggesting that the basalt formed under a condition of lower temperature and pressure.
