Helium, argon, and xenon were measured in vesicles of MORB from a variety of locations and in sequential crushing steps in two locations. Melting extractions, compared to these data, indicate that most of the trapped ...
Glasses from two EPR and two MAR basalts were crushed sequentially to release argon in a stepwise fashion. The results show a variation in ratios within each sample, indicating that the argon trapped in the vesicles has ...
