Foid monzodiorite and foid monzogabbro are silica-undersaturated plutonic rocks that are closely related to monzonite, monzodiorite, and monzogabbro. These rocks contain essential …

A foid-dioritoid where K-feldspar is >50-10% of feldspars. Foid-monzodiorite is in section 13 of the QAPF diagram. A subgroup of the Feldspar Group, poor in calcium, and mostly rich in …

Foid Monzodiorite: "A collective term for alkaline plutonic rocks consisting of feldspathoids (10%-60% of the felsic minerals), intermediate plagioclase with subordinate alkali feldspar and large …

If quartz is more than 5% (but less than 20%) of the felsic minerals, these rocks can be classified as quartz monzodiorite/quartz monzogabbro. Alternatively, if foids up to 10% are present, they …

A diorite with <10% foids and 10-35% alkali feldspar on the QAPF diagram. Foid-bearing-monzodiorite is in section 9' of the QAPF diagram. A subgroup of the Feldspar Group, poor in …

The difference between foid monzodiorite and foid monzogabbro is the composition of plagioclase, more sodic in monzodiorite (< An 50) and more calcic in monzogabbro (> An 50). …

A foid-monzodiorite where cancrinite is the most abundant foid. Foid-monzodiorite is in section 13 of the QAPF diagram. A subgroup of the Feldspar Group, poor in calcium, and mostly rich in …

monzodiorite is a coarse-grained igneous rock consisting of essential plagioclase feldspar, orthoclase feldspar, hornblende, and biotite, with or without pyroxene. Plagioclase is the …

IUGS diagram for naming plutonic/phaneritic igneous rocks with M<90% and with felspathoid present. This is a combination of the bottom halves of charts 1a and 1b on one diagram with a …

['Foid-monzodiorite - A type of foid-dioritic-rock. In the Rock Classification Scheme, it is a coarse-grained crystalline igneous rock whose mineral mode plots in field 13 of the quartz - alkali …
