Single grain Rb-Sr isotopic analysis of GA-1550 biotite, LP-6 biotite and Bern-4M muscovite 40Ar-39Ar dating standards
Rb-Sr isotopic systematics standard mica GA-1550 biotite LP-6 biotite Bern-4M muscovite
2017/8/10
Three standard minerals GA-1550 biotite, LP-6 biotite and Bern-4M muscovite used for K-Ar and 40Ar-39Ar dating have been investigated by the single grain Rb-Sr technique. Compared to the K-Ar and 40Ar...
