This article presents arguments against the long-held geological principle of uniformitarianism, which suggests that Earth's geological processes have remained constant over vast periods. The author contends that while modern geologists claim openness to catastrophism, their thinking remains rooted in uniformitarian assumptions, often relying on physical laws to infer slow, gradual processes. The article challenges this mindset by examining three sediment types – volcanic ash, diatomite, and chalk – demonstrating through case studies and recent research that rapid, potentially catastrophic depositional events better explain their formation, highlighting inadequacies in reductionist uniformitarian models that fail to account for complex interactions and past conditions unlike the present. Ultimately, the piece advocates for a willingness to consider alternative, sometimes catastrophic, hypotheses in geology.
