Incompatible Mineral Pairs in K-Rich Rocks

Part of the Springer Geology book series (SPRINGERGEOL)


The mineral pairs orthopyroxene–leucite, leucite–albite, and melilite –plagioclase are not observed together in natural K-rich silica-deficient igneous rocks formed under volcanic to subvolcanic conditions. The probable cause of incompatible relationship for these pairs are described in this chapter.
