Brief description Identified thirty or more years ago subduction is the return of cold, dense, oceanic lithosphere to the mantle and is one of the key dynamic elements of the plate tectonic paradigm. It is this process that is responsible for the 'Pacific Ring of Fire'. It is the root cause of many key geological processes and is a primary control of some of the earth's largest-scale physiographic features, including deep-sea trenches and mountain ranges. Using the important record of Cambrian in eastern Australia and in the comparable Canadian Atlantic margin, we will look at the causes and impact of the earliest stages of subduction as it first developed in the western Pacific and pre-cursor Atlantic 500 million years ago.
