Paleomagnetism in western Canada sedimentary basin: dating fluid flow and deformation events

摘要

The impetus provided by Lithoprobe's Alberta Basement Transect program has led to a tenfold increase in paleo- magnetic data for strata in the Western Canada Sedimentary Basin(WCSB). This paper aims to provide a synthesis of this research with emphasis on the results to date. They show that paleomagnetic methods can be used to reliably:(1) date dolomitization the strata, in petroleum reservoirs, and in Mississippi Valley-type(MVT)zinc-lead hydrothermal ore deposits;(2)narrowly constrain the ages of folding and faulting events; and(3)orient stored core for further geo- logic analysis to provide useful geologic information.
