Paleomagnetism of the Eocene Flat Creek pluton, Yukon: Tectonics of the Intermontane terranes and Mackenzie Mountains
The massive 53.6 Ma Flat Creek granitic pluton of the Nisling Plutonic Suite intrudes flat-lying volcanic rocks of the 70 Ma Carmacks Group in the Stikine Terrane of the Intermontane Belt in the Yukon. Specimens ( n = 334) from 22 sites in granite from the ~100 km 2 pluton plus 3 sites in cross-cutting 51.1 Ma Eocene andesitic dikes were tested using alternating field and thermal step demagnetization and magnetic susceptibility and saturation isothermal measurements. Magnetite was the sole important characteristic remanent magnetization (ChRM) carrier. Most granitic and andesitic specimens carried a lower temperature and coercivity normal-polarity A N ChRM and an antiparallel higher temperature and coercivity reversed A R component, but some specimens of both rock types carried just A R and some granitic specimens carried just A N components. Combining the A N and A R directions, the granite pluton yielded a mean direction of declination (D) = 165.2°, inclination (I) = −76.8°, (number of sites [N] = 31, radius of cone of 95% confidence [α 95 ] = 2.2°, precision parameter [k] = 139) and the dikes a mean D = 158.0°, I = −79.5°, (N = 3, α 95 = 6.0°, k = 423). Paleomagnetic contact tests proved inconclusive because of the contemporaneous and dual polarity remanence of the specimens. The pluton’s paleomagnetic pole indicates a nonsignificant northward displacement of 0.8° ± 4.6° and a significant clockwise rotation of 14° ± 10° for the Stikine Terrane relative to the North American craton after ca. 54 Ma. Regression analysis of ≤;54 Ma paleomagnetic motion estimates for all Intermontane terranes against time also shows nonsignificant translation with a significant rotation rate of 0.34° ± 0.11°/m.y. This implies that the Intermontane terranes since ca. 54 Ma have behaved as a quasi-coherent upper crustal plate that rotated atop a North American cratonic lower crust about a proximal near-vertical axis. It is speculated that the rotation was marked by westward extension in southern British Columbia and by eastward compression in the northern Cordillera, together amounting to ~550 ± 160 km of displacement orthogonal to the stable cratonic margin. The compression component in the north, driven by Pacific plate subduction and collision of the Yakutat terrane, is the suggested cause of arcuate orogenic uplift in the Mackenzie Mountains.

Paleomagnetic age for Zn-Pb mineralization at Robb Lake, northeastern British Columbia
Abstract Dating of Mississippi Valley-type (MVT) Pb-Zn-Ba ore deposits is a challenge because they usually occur in undeformed and unintruded platform carbonates and rarely contain minerals suitable for radiometric dating. However, these ores can be dated paleomagnctically and 10 such studies that meet current technical standards have been completed on major MVT deposits/districts. These studies give dates to within about ±15 m.y. For those districts where radiometric ages are available, the paleomagnetic age is usually supported. No radiometric method has been successful to within ± 15 m.y. in more than two of the districts. In no case is there another age that is defined by two different radiometric methods. In each case the paleomagnetic age corresponds to a major orogenic event in the surrounding or adjacent orogen. Finally the paleomagnetic ages constrain genetic models for forming most MVT deposits to those based on gravity-driven or compression-driven fluid flow either in the surrounding orogen or from the adjacent orogen.
