摘要
The capital of the world’s nickel，Sudbury in north Ontario，is named for the Sudbury Structure．The Sudbury Structure and its associated Cu-Ni sulphide deposits is a significant geological record on the earth． Detailed study of the Sudbury Structure has suggested that the Sudbury Structure is a violent structure，widely regarded as meteoritic shocking structure．The footwall rock of the structure is Precambrian metamorphic rocks which has subjected shock metamorphism and formed Sudbury Breccia partly．The Sudbury Igneous Complex(SIC)is a controversial igneous rocks，compositionally from quartz norite to granophyre and quartz diorite-offset dikes，for its special composition and geological occurrence．The hang-wall rock，Whitewater Group，is more complex and interpreted as an ignimbrite or the fallback breccia from the impact of a meteorite．Coincidentally，the Sudbury Structure is located on the east-tending Elliot Lake-Englehart positive gravity anomaly and at the“Junction”of three structure provinces，and also loeated on a big Cu-Ni metallic mineralization zone．．．
It is a milestone in Sudbury Structure research that the monograpgy，The Geology and Ore Deposits of the Sudbury Structure，was published by Ontario Geological Survey(OGS)in 1984．This year there will be a international symposium on the Sudbury Structure in Laurentian University．This paper is an introduction of Sudbury Structure to people who are not familiar with it．
