Although hydrocarbon-bearing fluids have been known from the alkaline igneous rocks of the Khibiny intrusion for many years, their origin remains enigmatic. A recently proposed model of post-magmatic HC generation through Fischer-Tropsch type reactions suggests a primary CO2 fluid. This hypothesis i...
