Abstract | ln the Cordillera of northwestern Canada, the Mount Harper volcanics (751 +261-18 Ma) of the Ogilvie Mountains may have formed coevally with the Little Dai basalts and the diabase intrusions (777.7 + 2
.51-1.8 Ma) of the Mackenzie Mountains. Comparison of the Mount Harper primary pole with reference potes /rom the Mackenzie Mountains and the Canadian Shield, suggests that the Mount Harper reg ion has rotated by at least 60°. Basalticflows of the
Mount Harper volcanic complex con tain at least three stable magnetic components. The primary component in hematite and probable magnetite has a pole roughly estimated at 140°W, 29°S (t::!..=6; A.95=12°). One secondary component, attributed to
synfolding burial heating or hematite formation, yields a steeply directed pole ( 166°W, 74°N; t::!..=8 sites; A.95=22°) similar in direction to a postfolding pole (178°W, 78°N; t::!..=4 sites; ,195=9°) derived from hematitic siltstone elsewhere in
the complex. |
