Deformed Quartz from the First Drill Cores at the Ilkurlka Circular Geophysical Anomaly in Western Australia: A Possible Impact Structure
Abstract
Results from a survey of minerals from samples spanning two boreholes through the Ilkurlka anomaly are presented. We describe concussion and sub-planar fractures in quartz, and kink bands in biotite, observed by BSE imaging.
