Hi everybody,
Does anybody know if some oxygen isotope
studies on abiogenic (specially precious) opal exist ?
I am aware of many studies on diagenesis of biogenic opal
(cherts,...), but very few on non-biogenic opal (most of them
from oceanic environments-silica chimneys, etc-,
but none from continental environments).
Thanks in advance for some informations.
Cheers
Albert Gilg
