Quartz Microstructures from the Sambagawa Metamorphic Rocks, Southwest Japan: Indicators of Deformation Conditions during Exhumation

Abstract: The Sambagawa metamorphic rocks in central Shikoku, southwest Japan consist of an inverted metamorphic sequence from the upper chlorite to oligoclase-biotite zones at the lower structural level (LSL), which is overlain by a normal metamorphic sequence consisting of the albite-biotite and garnet zones at the upper structural level (USL). These sequences form a large-scale recumbent fold called the Besshi nappe. To unravel the mechanism of recrystallization and physical conditions in quartz, and their relation t… Show more

“…Based on the difference between the mechanisms of dynamic recrystallization and the operative slip system in quartz, it was inferred that the samples GQS1*, 2 and 3 could have been deformed at increasing temperatures of $300-350 C, $350-400 C, and $400-500 C (e.g. Takeshita & Wenk, 1988;Takeshita, 1996Takeshita, , 2021Stipp et al, 2002;Behr & Platt, 2011;Czertowicz et al, 2019;Tokle et al, 2019, see a large arrow in Figure 9).…”
