Data from: Modulation of deformation by magmatic tempo, Coast Mountains Batholith, British Columbia, Canada

Abstract

The data is used to constrain the tectonmagmatic evolution of the southern Coast Mountains batholith from ca. 120 – 50 Ma.  Three periods of deformation coincide spatially and temporally with three periods of high-flux magmatism derived from mantle sources.  These results suggest that the deformation was modulated by episodic magmatism and so was not a driver of episodic magmatism.  During a period of high-flux magmatism, deformation style within the active arc reflects coeval relative plate motions; the timing of shifts in plate motions outside of these periods may not be recorded by the deformation.
