名义上无水矿物( Nominally Anhydrous Minerals ,简称 NAMs )即理想化学式中不含氢的矿物,主要包括长石、石榴石、辉石、橄榄石、石英等及其高压结构相,但通过对这些矿物的研究发现几乎所有的 NAMs 都含有微量的通常以 OH - 或 H 2 O (少数为 H 3 O + 、 H 3 O 2 - 、 H 5 O 2 + )形式赋存于 ...
Quantitative Spectroscopic studies. Spectroscopic methods remain the most important and convenient way to establish the presence of hydrous components in minerals and to differentiate water from hydroxide ions. They are sensitive, rapidly applied, and convenient to conduct, but are not intrinsic ...
Hydrogen is one of the most pervasive elements in the crust and upper mantle of our planet. It is a mobile, reactive component which can cause major changes in the chemical, physical, rheological, and electronic properties of the host phase. Much of the effort of our group is directed at investigat ...
