摘　　要：本文以河南省西峡县杨乃沟泥质片岩为研究对象，在矿物学工作的基础上，把Greenwood矩阵代数投影分析方法成功地运用到了实际的矿物共生分析中，讨论了杨乃沟泥质片岩的矿物共生关系和某些组分对共生关系的影响，更进一步地揭示了该方法的潜在意义和优越性，同时表明：矩阵代数投影分析方法不仅适用于具理想组分的体系，而且也适用于实际的矿物岩石体系。Based on the mineralogical study of pelitic schists in Yangnaigou, Xixia County, Henan Province, the application of matrix projecting analysis reported by Greenwood in 1975 to the actual mineral paragenesis is described in this paper. The mineral paragehesis and the influence of some comPOnents on it are discussed as well. It is shown that the method is applicable not only to endmember mineral systems, but also to actual mineral-rock systems.
