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.

根据单斜辉石-熔体平衡原理计算了富辉橄玄岩和玄武岩中斑晶相辉石形成的温度和压力,前者变化范围主要集中在1345~1366℃和1.75~2.05GPa,其深度相当于58-67km,平均的地温梯度大约20~24℃/km,说明该区具有异常的热或地温梯度,这可能是导致本区斑岩铜矿形成的主要原因之一;后者的温度和压力都相对较低,分别为1129~1191℃和1.19~1.60Gpa,而相应的深度为39~53km,暗示着玄武岩是在相对低温低压的环境中形成的演化岩浆。
