Back in Hutton’s day when it was widely believed that Earth came into creation only about 6000 years ago, the narration of […]
Chang Xu recently completed her undergraduate degree in Geology at the School of Earth Sciences and Engineering at Sun Yat-sen University in Guangzhou, China. She is now a Masters degree candidate in Sun Yat-sen University studying structural geology in South China. Initially Chang wasn’t interested in geology, but learned to love geology during her first […]

The Lewisian Gneiss Complex of the Scottish highlands is of great historical significance and remains a textbook example of how lower-crustal processes can operate, and of how sound field observations can unravel the geological history of a particularly complex area. However, despite the considerable volume of studies that were conducted in the region during the […]
A couple of weeks ago, I had the opportunity to join a friend in a single prop plane to some key geologic localities that can be observed from the air better than they can be seen from the ground. While most of us use Google Earth for that, seeing an oblique view from 2-3 thousand […]
