Our results show that the two-pyroxenes geothermometer proposed by Bertrand and Mercier(1985)is the best one update for estimating temperatures of the mantle peridotite xenoliths. Their method of calibration also has a general significance.

• 结果表明:(1)Bertrand and Mercier(1985)提出的二辉石温度计是目前为止最适合用于幔源包体的温度估计,其推导方法也有普遍意义。
