The Texan Permian and Its Mesozoic Types of Fossils
It differs from phenocrystic quartz in being allotriomorphic, without glass
inclusions, and in containing in general a greater abundance of liquid inclusions.
It is the characterizing quartz of granitic rocks, and on that account Eosenbusch
has ...

Principles of Igneous and Metamorphic Petrology
At slightly lower M' values, plagioclase also becomes a phenocrystic phase, and
its separation can account for the A1203 content remaining constant and the CaO
content falling in the less magnesian rocks. Oxides such as P205, K20, NaZO, ...

Igneous and Metamorphic Petrology
Mineralogical and modal contrasts (Wilson, 1989) are as follows: Olivine is
exclusively a phenocrystic phase in tholeiites and is quite Mg-rich, Fo90-70,
whereas in alkaline basalts it is both a phenocrystic and a groundmass phase
and is more ...
