GSA used continent-scale scientific data to map mantle-edge thermal gradients along craton margins, identifying a critical change in thickness of the lithosphere 170 kms below surface. 140° Golden Grove Julimar Perth Prominent Hill Nimbus Olympic Dam Mount Coffin Beltana Broken Hill Redbank Project Tenements MINES & DEPOSITS Copper, >10 Mt Copper, 1-10 Mt Copper, <1 Mt Lead, 1-10 Mt Lead, <1 Mt A Zinc, >10 Mt Zinc, 1-10 Mt V Zinc, <1 Mt Nickel, >10 Mt LAB Depth Contours (km) Major Towns State Borders Adelaide Melbourne Brisbane C 136° Redbank Sydney McArthur River Canberra NT Walford Creek Century Hobart I Mount Isa Line 94MTI-01 NT WA QLD SA 18° NSW VIC QLD TAS Line 07GA-IG GSA interpreted change in lithosphere defines craton margins, noting some 85% of sediment-hosted base metals (copper, lead, zinc) occur within 200km of the transition between thick and thin lithosphere.
