Impact cratering is a fundamental and ubiquitous geological process in the Solar System. It is considered the most important surface process on the Moon, Mercury, asteroids, and over large parts of the more geologically active planets of Mars and Venus. We now know that meteorite impact events have also played an important role throughout Earth's history, shaping the geological landscape, affecting the evolution of life, and producing mineral and hydrocarbon deposits of major economic significance. This research program will further our understanding of meteorite impact events and their beneficial scientific and economic effects. This is particularly important for Canada, which draws such a huge amount of wealth from the mining within the Sudbury impact structure - the richest mining district in North America.

撞击坑是太阳系中普遍存在的基本地质过程。它被认为是月球、水星、小行星以及火星和金星等大部分地质活动更活跃的行星上最重要的表面过程。我们现在知道，陨石撞击事件在整个地球历史上也发挥了重要作用，塑造了地质景观，影响了生命的进化，并产生了具有重大经济意义的矿物和碳氢化合物矿床。这项研究计划将进一步加深我们对陨石撞击事件及其有益的科学和经济影响的了解。这对加拿大来说尤其重要，因为加拿大从萨德伯里冲击构造内的采矿中获得了如此巨大的财富——萨德伯里是北美最富有的矿区。
