Köppen climate type:


Two masses of carbonatite, with subordinate ijolite and nepheline syenite, emplaced in basement granite. Syenitic fenites with aegirine-augite occur near the ijolite-nepheline syenite intrusives, and quartz-bearing fenites with aegirine and sodic amphibole are more peripheral.

Not to be confused with the Toror complex [https://www.mindat.org/loc-209283.html]
