The proportions of ferric and ferrous iron in a given amphibole are determined by a complex interaction between intensive parameters such as temperature and pressure and crystal-chemical parameters such as crystal structure. Research to determine these properties will be continued. The approach consists of experimental treatment of ampbiboles followed by thorough characterization of run products by x-ray, optical, wet chemical, and spectroscopic techniques. The results will have specific applications in relating the compositions of natural amphiboles to intensive parameters in the environment of formation. More fundamental understanding will come from the defining of the interralationship between chemical, crysallographic, and thermodynamic properties of a major rock- forming mineral group. The end result will be a better understanding of amphibole group minerals and the environments in which rocks have formed.

在给定的角闪洞中，铁和亚铁的比例是由温度和压力等密集参数与晶体结构等晶体化学参数之间的复杂相互作用决定的。确定这些特性的研究将继续进行。该方法包括对双酚类化合物进行实验处理，然后通过x射线、光学、湿化学和光谱技术对运行产物进行彻底表征。这些结果将在将天然角闪石的组成与地层环境中的密集参数联系起来方面具有特定的应用。更基本的理解将来自对主要造岩矿物群的化学、结晶学和热力学性质之间的相互关系的定义。最终的结果将是更好地了解角闪洞群矿物和岩石形成的环境。
