  1. The author suggests that for those kinds of samples like ophiolite which formed in the underwater environment and had very low potassium content, it should be better to determine their formation age by the sm - nd method as it is less sensitive to alteration. however, the step heating 40ar - 39ar spectra could often reflect the influence of later geological events on isotope system

    認為對蛇綠巖這類形成於水下環境，含鉀極低的樣品，其巖體的形成年齡宜選用對蝕變影響反應不明顯的sm - nd方法測定；但階段升溫~ （
