We present the first results of fission-track dating of apatite monofractions from two rock samples taken from the Southern carbonatite massif of the world's largest alkaline ultrabasic Guli pluton (similar to 250 Ma), located within the Maymecha-Kotuy region of the Siberain Traps. Based on the apatite fission-track data and computer modeling, we propose two alternative model of the Guli pluton's tectonothermal history. The models suggest (1) rapid post-magmatic cooling of the studied rocks in hypabyssal conditions at depth about 1.5 km, or (2) their burial under a 2-3 km thick volcano-sedimentary cover and reheating above 110 degrees C, followed by uplift and exhumation ca. 218 Ma.Note
