Slip-system and EBSD analysis on compressively deformed, fine-grained polycrystalline olivine

Farla, Robert; Fitz Gerald, John; Kokkonen, Harri; Halfpenny, Angela; Faul, Ulrich H; Jackson, Ian

Description

A slip-system analysis was performed on two synthetic compressively deformed olivine aggregates, derived from experimental solution-gelation (sol-gel) and natural San Carlos precursors to determine how dislocation density relates to Schmid factor for slip in olivine. Individual grain orientations were measured with electron backscatter diffraction. Using decorated dislocations, grain populations were separated into subsets of high versus low dislocation density. Analysis of preferred...[Show more]
