Field evidence suggests that the fold developed during prograde metamorphism and penetrative deformation when the Indian plate was underthrust beneath Indus ophiolitic mElange (DiPietro and Lawrence, 1991).

The race this time is between Professor McGovern ("the underthrust of his learning could carry his conversation to the uplands of history") and Old Pro Nixon ("then his mind locked into tight reasoning").

Located at an altitude of approximately 2,700 m in the rugged mountainous terrain of Enga province in the highlands of P.N.G., the Porgera intrusive system lies 24 km south of the Lagaip Fault which marks where the leading, northern edge of the Australian continental plate starts to underthrust the central mountain belt of P.N.G.
