Is so-called Al-Mg isochron for a meteorite CAI a two component mixing line?

Internal Al–Mg isotope systematics of a Type B CAI: Remelting of refractory precursor solids

High precision SIMS Al–Mg isotope analyses were performed for a pristine Type B1 CAI Leoville 3535-1 on multiple mineral phases that include aluminum-rich zoned melilite mantle (Åk20–Åk60), magnesium-rich melilite (Åk70), fassaite, spinel and anorthite in the core. The data yield a well-defined internal isochron with an inferred initial Al/Al ratio of (5.002 ± 0.065) 10 , which is lower than th...

A Case of (So-Called) Snake-Bite

a snake, about hnlf-an-hour previously. The Native Doctor of the E. B. R. Co. had arrived before me, and applied an Esrnareh's elastic band as a ligature, and had incised, what he believed to be, the fang punctures. On arrival I found the man lying on a maichan, his right arm, which had been ligatured above the elbow, was tense and bleeding at the incised part. He was apparently drowsy and only...
