isochrone

基本解釋

Studies of isochron luminescence dating with sand-sized grains.
粗顆粒的等時線釋光方法研究。
The same samples were also dated by mineral Rb-Sr isochron method.
結(jié)果表明，花崗巖和片麻巖礦物的氧同位素溫度大小順序為：角閃石>磁鐵礦>榍石>石英>黑云母>長石，遵循緩慢冷卻條件下擴散控制的氧同位素交換封閉順序，指示這些巖石沒有受到后期熱液蝕變的擾動。
It concludes with a discussion on the scientific validity of isochron dating.
這里包括許多等時線測年的科學(xué)有效性討論。
Its age determined by Rb-Sr isochron is 306 Ma, suggesting that it was formed at Hercynian.
據(jù)Rb-Sr等時線測定,其年令值為306Ma,說明它形成于海西期。
The isochron of whole rock Rb-Sr of intrusive during Caledonian in xiao Qinling mountain is 503 Ma.
小秦嶺加里東期侵入巖的全巖Rb－Sr等時線年齡值為503Ma。
