Abstract

The nature of water in hydrous silica (Monterey diatomite) was studied by measuring the H-isotopes of successive water increments evolved while heating silica to 1000oC under vacuum. The exchangeable water is indistinguishable from other water, but at >700oC, water evolved from hydroxyl groups may preserve a geologically useful isotopic record.-K.A.R.
