KΓΆppen climate type:
Small metasedimentary hornfels xenoliths in a gabbroic body.
At Maratakka the sand-covered Precambrian basement is not exposed.
Drilling showed the basement to consist of a mafic body, a few kilometers in size, surrounded by granite, presumably with metasedimentary enclaves (Bosma et al., 1975).
The mafic body consists of quartz gabbro-norite and biotite-quartz diorite and is cut locally by granite veins.
The metasedimentary hornfels xenoliths in the gabbroic body contain, in addition to grandidierite, antiperthitic andesine, perthite, cordierite, biotite, spinel, magnetite, and minor corundum, apatite, zircon, and ilmenite.
Biotite forms poikiloblasts of random orientation in a fine-grained granoblastic matrix of andesine, perthite, and cordierite.
Magnetite and dark green spinel occur as small, euhedral crystals, partly enclosed in biotite, as aggregates in feldspar, and as irregular poikiloblastic masses.
Other xenoliths, without grandidierite, contain additional sillimanite (with or without quartz) and locally some andalusite.
In one sample a grandidierite-bearing hornfels occurs together with a hornfels of fine-grained, granoblastic andesine and poikiloblastic hypersthene.
