Introduction

MAPCIS is a marine oblique impact hitting the Centralian Superbasin over thick continental crust with a northeast to the southwest trajectory centered at 25°32’55.66″S 131°23’21.50″E with initial contact about 140 km to the northeast creating an approximately 600km diameter complex peak ring crater with bilateral symmetries, uprange-downrange components along with an exposed circular crater rim. MAPCIS is age constrained to end Ediacaran/early Cambrian consistent with pЄ-Є boundary. We will show panoply of mega, macro, micro and elemental evidence to support the age, size, trajectory and location of this impact with this and successive papers. We will finish with the implications of MAPCIS changing our understanding of geology and Earth history. This first paper is authored primarily by Daniel Connelly.
