Köppen climate type:
Loose blocks of pegmatite and its quartz granulite host, that most likely formed by break up of outcrop without further transport.
Nodules up to several centimeters across in the granulites are rich in orthopyroxene and sillimamte, sapphirine occurs locally. Both sillimamte and orthopyroxene are present in two generations. Two generations of garnet, which is less abundant, are also present. Cordierite occurs in the sillimamte-orthopyroxene aggregates in a few sections. Streaking out of sillimamte-orthopyroxene aggregates, granulation of feldspar and suturing of quartz grain boundaries are all indicative of partial cataclasis of the granulites, which has resulted in a flity appearance in some specimens.
Pegmatite veins about 5 cm thick cut layering in the host granulite. In hand specimens the pegmatite is light colored and contains orthopyroxene grains up to 2 cm long and flattened aggregates of orange wagnerite up to 2 cm across. In contrast to the "Christmas Point" pegmatite, sillimanite prisms do not exceed 1 mm in width and the coarse orthopyroxene appears to be an early formed mineral, which is partly replaced by garnet. Feldspar is mostly a fine intergrowth of alkali feldspar and plagioclase (mesoperthite). Cordiente shows considerable yellow pleochroism and anomalous interference colors; it locally encloses sillimanite and a fine-grained orthopyroxene, which appears to be later-formed than the coarser grains. Surinamite was found enclosed in cordierite with sillimanite, garnet and biotite. Kyanite and andalusite occur in either quartz or feldspar but are mostly separated from the latter by a selvage of quartz. A selvage of apatite commonly surrounds wagnerite aggregates.
