Matching magnetic trends and patterns across the Tintina fault, Alaska and Canada--evidence for offset of about 490 kilometers: Chapter C in Recent U.S. Geological Survey studies in the Tintina Gold Province, Alaska, United States, and Yukon, Canada--r

Magnetic anomaly patterns on opposite sides of the
mapped Tintina fault in eastern Alaska and western Canada
show an apparent offset of about 490 kilometers (km),
probably of Eocene age. This estimate is compared with
previous geologically based estimates of 400 to 430 km and
paleomagnetically based estimates of more than 1,100 km.
The apparent geophysical alignments have geologic implications that deserve further study.
