The Lomagundi Event (LE) was a period in Paleoproterozoic Earth history during which carbon isotopic composition of carbonates deposited globally record highly positive isotopic values (averaging at +8 ‰ VPDB). Current geochronological constraints from basins worldwide have bracketed the LE between...
