众所周知,应用热力学理论解决地质问题的基本前提是,必须拥有足够的、尽可能准确的矿物热力学数据。实验相平衡研究是获得矿物热力学数据的重要手段之一。透闪石是很重要的一种旷物。Boyd(1959)曾对合成透闪石的低压稳定性作过研究。至今他的曲线仍波广泛引用,并用以产生透闪石的热力学数据(如Zen,1972;Helgeson,1978;Veblen,1982),由于Boyd的文章中缺乏有关数据表,人们在对他的数据进行热力学分析时,就只得从他的曲线直接取用P—T数据;又由于在我们的F—OH透闪石固溶体体系热力学稳定关系的实验研究中,须以这样一条曲线作基线,因而有必要对透闪石的热力学稳定性重新进行实验研究。
It is well-known that the basic premise for applying thermodynamic theory to solve geological problems is to have enough and as accurate mineral thermodynamic data as possible. Experimental phase equilibrium study is one of the important means to get the thermodynamic data of minerals. Tremolite is a very important wasteland. Boyd (1959) studied the low pressure stability of synthetic tremolite. His curves so far have been widely cited and used to generate tremolite thermodynamic data (eg Zen, 1972; Helgeson, 1978; Veblen, 1982). Because of the lack of relevant data sheets in Boyd’s article, Thermodynamic analysis, P-T data have to be taken directly from his curve; and since it is necessary to base such a curve on the experimental study of the thermodynamic stability of our F-OH tremolite solid solution system The thermodynamic stability of tremolite re-experimental study.
