Paleomagnetic evidence from 37 sites of the partly red-pigmented siliciclastic Tsezotene Formation supports a recently proposed apparent polar wander path for the Hadrynian Mackenzie Mountains supergroup (MMs). The probable primary remanence has a direction at D¿, I¿=271, +24 (k=15; α950=8) with an associated pole TA (12 ¿N, 214 ¿W; N=23 specimens; Δp¿=5,9). TA becomes the oldest pole from the MMS. It helps bridge the gap between the apparently youngest poles of the Grenville Loop (about 0.88 Ga) and the suggested younger poles from the MMs. A secondary pole TB (23 ¿N, 198 ¿W; N=18 sites; Δp¿, Δm¿=3,5), derived from a magnetic direction in hematite pigment (D¿, I¿=263, +48; k=73; α95¿=4), supports a magnetization found in the overlaying ''Copper cycle'' and in younger units of the MMs as a pervasive overprint. Another secondary pole Tc (63 ¿N, 141 ¿W; N=29 sites; Δp¿, Δm¿=6,6), derived from a magnetization (D¿, I¿=317, +87; k=89; α95¿=3) partly residing in another phase of hematite pigment, is of postfolding age (post-Paleocene). This study demonstrates the importance of using several treatment methods, singly and in combination, when analyzing complex magnetizations. |
