穩(wěn)定性同位素是指就目前檢測(cè)技術(shù)來(lái)說(shuō),尚不能發(fā)現(xiàn)自行衰變的同位素,如12C、13C、16O、18O等。
如12C或者16O,存在的比例很高,大多超過(guò)99%,而13C或者18O比例很低。一般提及穩(wěn)定性同位素,大多是指在自然界中含量較低的穩(wěn)定性同位素,即13C,18O。
含有穩(wěn)定性同位素的分子,與正常的分子相比,擁有相同的化學(xué)性質(zhì),但由于重量稍大,物理性質(zhì)有著一定的差異,所以在一些過(guò)程中,同位素的含量會(huì)發(fā)生變化,這就是同位素分餾(Isotope Fractionation),正因?yàn)檫@個(gè)特性,穩(wěn)定性同位素在地質(zhì)歷史中的變化為研究成巖作用提供了珍貴的地球化學(xué)信息,對(duì)了解環(huán)境演化具有重大意義。
