The Maquinita Granodiorite is a Precambrian pluton that crops out in the northern Tusas Mountains of New Mexico.

The formation takes the form of many small dikes and plutons intruding the Moppin Complex.

Its modal composition is 57% albite-oligoclase, 27% quartz, 10% biotite, 4% muscovite, and 1% each epidote and microcline.

[4] Mineralization veins in the northern Tusas Mountains appear to be coeval with the Maquinita Granodiorite.

[6] The current designation was assigned by Fred Bauer during the geologic mapping of the Las Tablas area in 1958, who named it for outcrops in Maquinitas Canyon (36°41′27″N 106°10′29″W / 36.6907°N 106.1747°W / 36.6907; -106.1747) [1]
