Meteorite Impact on Earth

Friday September 24 – 7:30 p.m. at the Almonte United Church Social Hall

Speaker: Blythe Robertson

Topic: Meteorite Impact on Earth 

Synopsis:

Canada has led the world in establishing the evidence that Earth has experienced the same bombardment history depicted by the large and ubiquitous impact craters on the Moon and other terrestrial planets. Dr. Robertson’s research on hypervelocity impact on earth has involved the study of large meteorite craters in all regions of Canada, with a focus on the effects on the target rocks and minerals of the extreme pressures and temperatures generated by a major impact. From his experience as part of the scientific team, Blyth will summarize this research by taking the audience on a tour of many of the world’s impressive craters, discussing the evidence for their origin and particular form, and their possible influences on the geologic and biologic evolution of our planet.

Speaker’s Profile:

Blyth Robertson, a native of Ottawa, earned degrees in geology from Carleton University, The University of Pennsylvania and The University of Durham, England. His entire research and management career, spanning over forty years, has been spent in the federal Department of Natural Resources, with the Earth Physics Branch and the Geological Survey of Canada, where he is currently an emeritus scientist. One of his continuing interests is geoscience education and promoting geoscience awareness to the general public, which he pursues through membership on the Ottawa-Gatineau Geoheritage Committee, the Canadian National Committee for the International Year of Planet Earth, and the Canadian Geoscience Education Network.
