【摘要】 对十六个不同地质产状的镁铝榴石-铁铝榴石系列样品进行了穆斯堡尔谱研究。结果表明Fe²⁺的四极矩双线的不对称程度A_s与样品地质产状密切相关:来自金伯利岩中的镁铝榴石A_s=（23±2）％;来自地幔包体中的镁铝榴石A_s=（16±1）％,来自各种变质岩中的镁铝榴石A_s=（6±3）％。更多还原

【Abstract】 Sixteen samples of pyrope-almandite series from different geological envi-ronments were studied with Mossbauer spectroscopy. It has been found thatthe asymmetry （As） of Fe²⁺ doublet depends strongly on the geologicalenvironments; A_s （23±2）% for samples of pyrope from Kimberlites; A_s （16±1）% for pyrope in mantle inclusions; A_s （6±3）% for almandite from metamorphic rocks.更多还原
