Abstract

A large fold structure in the upper part of the Lilloise layered intrusion provides evidence of the existence of pore liquid through a thickness of some 300 m of layered cumulate rocks at the time of its formation. The Lilloise magma fractionated from peridotitic through gabbroic layered cumulates to the stage of producing dioritic plagioclase-amphibole cumulates. At this point massive cauldron subsidence of the whole intrusion occurred while the dioritic cumulates were still in the process of formation, resulting in a large soft-sediment type of fold structure.
