Sleaford orogeny
TheSleafordorogenywas an event in the assembly of theGawler Craton,which now underlies theEyre PeninsulainSouth Australia.Between 2.46 and 2.41 billion years ago in theProterozoic,the Sleaford and Mulgathing complexes emplaced among the older 3.15 billion year oldArcheanCooyerdoo Granite 2.82 billion year old Coolanie Gneiss with sedimentary,felsicandultramaficigneous rocks. The overlapping Sleaford orogeny caused deformation andgreenschistandgranulite-grade metamorphism on the sequence ofmetamorphic facies.[1][2]
