Adriana Ocampo has led six research expeditions to study what geological formation that is more than 180 km in diameter and 20 km in depth
Adriana Ocampo Adriana Ocampo is a Colombian planetary geologist and the Science Program Manager at NASA Headquarters. Her research contributed to the understanding of the Chicxulub impact crater. She has led six research expeditions to the Chicxulub impact site. Ocampo and her colleagues also discovered the Aorounga Crater Chain in Chad in 1996.
Eramosa The term was first used for a stratigraphic unit by Williams (1915) who named the Eramosa Member (of the Lockport Formation) for the bituminous dolomites exposed below the Guelph Formation along the Eramosa River, northeast of Guelph, Ontario. No detailed description of the type section has ever been published, and the status of the unit has been subject to many different interpretations. Until recently, the Eramosa in Ontario was regarded as the highest Member of the Lockport Formation, with gradational contacts with the Goat Island Member (below) and the Guelph Formation (above). In 1995, the US Geological Survey proposed a revised stratigraphy based on studies in the Niagara region. It extended the Lockport to Group status and included, from base to top, the Gasport, Goat Island, Eramosa, and Guelph as Formations within the Lockport Group. In a “reference section” in the Niagara River Gorge, the Eramosa was divided into six “units” recognized throughout the Niagara region, but a shaley lower unit previously named for the Hamilton area (the Vinemount Member) was transferred to the Goat Island Formation. Brunton (2009) has proposed a revision for Ontario which restores the Vinemount Member to the Eramosa and recognizes two other members.
