WebbIn current usage, a metamorphic facies is a set of metamorphic mineral assemblages, repeatedly associated in space and time, such that there is a constant and therefore predictable relation between mineral composition and chemical composition. The facies concept is more or less observation-based. Webb23 mars 2012 · Abstract. One of the often-stated goals of principal component analysis is to reduce into a low-dimensional space most of the essential information contained in a high-dimensional space. According to several reasonable criteria, principal components do this optimally. From a practical point of view, however, principal components suffer from …
