At high degrees of partial melting of the crust, granitoids such as tonalite, granodiorite and monzonite can be produced, but other mechanisms are typically important in producing them.

"' Larvikite "'is an igneous rock, specifically a variety of monzonite, notable for the presence of handsome, thumbnail-sized crystals of feldspar.

In 1964, C . A . Hopson grouped the Ellicott City Granodiorite with the Guilford Quartz Monzonite and the Woodstock Quartz Monzonite as " Late-kinematic intrusive masses ."

The district is a highly faulted area, intruded with Tertiary quartz monzonite porphyries, on the east side of the Arkansas River graben, part of the Rio Grande Rift system.

Upstream from the Boy Scout camp the gorges are full of mica schist and gneiss ( metamorphosed sedimentary rocks ), and granodiorite, quartz monzonite, and quartz diorite ( granatic rocks ).
47.
The rocks are all composed of quartz monzonite, a very rough type of granite made even more so as there is no snow or ice to polish it as in places like Yosemite.

The extent of this intrusion was originally mapped in 1892 Hopson grouped the Woodstock Quartz Monzonite with the Ellicott City Granodiorite and the Guilford Quartz Monzonite as " Late-kinematic intrusive masses ."

These rock types include iron-rich diorite, gabbro, and norite; leucocratic mafic rocks such as leucotroctolite and leuconorite; and iron-rich felsic rocks, including monzonite and rapakivi granite.
