Bands in volcanic rocks are deformed by inclusions, such as bubbles and crystals. The shape of deformed bands is compared with theoretical models for flow around inclusions. Deformation through either simple or pure shear can be distinguished for phenocrysts, but not bubbles. Studying band deformation at the microscale thus complements other textural measurements and structural approaches for reconstructing the kinematics and dynamics of lava flows.
