G.C. Herman,
PhD TECTONICS BLOG
Rev. 2022-01-04, 2021-07-26
Welcome to my tectonics blog. I'm a geologist that specializes in structural geology, groundwater flow in fractured rocks, and impact tectonics. I am blogging about my observations and interpretations of natural phenomenon that I marvel at, wonder how it works, and seek the answers. Sometimes my interpretations differ from popular theory. We are in a formative stage of understanding tectonic processes on terrestrial planets. At the coincident onset of the digital age and my career, we didn't have the perspectives that the recent technological bloom has afforded us. Modern computing methods and remote-sensing innovations now provide the tools to solve old problems in new ways. But the pace of technological growth and data procurement is outpacing the rate at which our scientific paradigms evolve. A major hurdle facing modern breakthroughs in understanding hidden tectonic processes is the leap to include punctuated, extraterrestrial and catastrophic agents into tectonic theory, now guided solely by uniformitarianism. The bombardment of Earth by bolides is a periodic process but the tectonic strains they impart are variable and subject to tectonic inheritance. This blog benefits from the global connectivity that we have now to point out some major aspects of plate-tectonics on both Earth and Mars stemming from catastrophic events that are missing in current theory. I hope you enjoy and benefit from the content. |
