Tectonic Pattern

A significant correlation exists between direction patterns in magnetic and tectonic trends on the northern two thirds of Texada Island, British Columbia, Canada. The patterns were analyzed in further detail by dividing the area into regions based on amplitudes of magnetic anomalies and on patterns in the magnetic trends. A technique involving smoothing and crosscorrelation was applied in the examination of the relationships between the patterns. The regions established on a magnetic basis also are distinct on the basis of tectonic pattern. However, correlation between the magnetic and tectonic patterns varies from region to region within the area. The directions N 50° W, N-S, and E-W, common throughout the coastal area of British Columbia, are the most widespread in the patterns studied on Texada Island. A distinctive zone, identified as a fault zone cutting across the island with a trend of N 20°W stands out in the patterns.

Ultramafic rocks of the Hozameen, Bridge River, and Cache Creek ophiolite assemblages show much variety. The Coquihalla belt of the Hozameen ophiolite assemblage, almost completely serpentinized, is elongate, narrow, and lies along a major fault. Three ultramafic bodies from the Bridge River ophiolite differ markedly from each other. (1) The Pioneer peridotite is a relatively small lens (4 km by 2 km), unaltered, well layered, and fault bounded. (2) The Shulaps body, one of the largest in British Columbia, is bounded on the northeast by a major fault and shows a wide mélange zone on the southwest. (3) A serpentinite body at Lillooet appears to be a steeply dipping slab in the Fraser River fault zone. At Cache Creek, serpentinite bodies are small and appear to be fragments in a mélange. Layers, transgressive sheets, and pods in the Pioneer and Shulaps bodies originated in the mantle, probably by one or several processes: metamorphic differentiation, metasomatism, and mechanical injection. Some ultramafic bodies were emplaced onto the crust by obduction but others, strongly serpentinized, that lie in fault zones may have been squeezed into their present positions.
