Fossil Ice Crystals: An Instance of the Practical Value of "Pure Science"

"Fossil Ice Crystals: An Instance of the Practical Value of 'Pure Science'" by Udden is a scientific publication written in the early 20th century. This work primarily focuses on the significance of geological observations, particularly the study of fossilized ice crystal markings found in various sedimentary rocks. Udden aims to demonstrate how seemingly insignificant geological phenomena can have important practical applications, particularly in the context of understanding and locating natural resources. In the text, Udden recounts his fieldwork that led to the discovery of peculiar ice crystal markings in fossilized rock layers across different locations, including the Black Hills, South Dakota, and various sites in Texas. He meticulously documents his observations, detailing the formation and patterns of these ice crystals and their implications for understanding past climatic conditions and geological processes. Eventually, he illustrates the practical value of his findings in the context of mining geology, showing how knowledge of these crystal patterns can help locate valuable ore deposits. Udden’s work emphasizes the intertwined nature of pure scientific inquiry and practical applications in geology.
