Hi everybody,
I have encountered "buchites" in my work. To all: buchites are an old
term for contact metamorphism-related glasses. Does anybody know modern
analytical work on these guys? I am also interested in state-of-the-art
studies of fenitization, brecciation related to fenitization.
Did anybody read about dissolution of halite accompanied by explosions?
I found a remark, that halite can host rather large quantities of gas
(i.e. CO2), after pressure release, halite is supposed to dissolve and
the expanding gas can fracture rocks (!?).
thank you and best wishes
