A Geognostical Essay on the Superposition of Rocks (Classic Reprint): In Both Hemispheres - Softcover
Synopsis
Unearth how rocks tell the story of the earth from Mexico to Hungary. This edition presents a clear view of how geognostic ideas describe the layering and movement of rocks, using concrete examples from classic field notes.
The pages reveal how geologists observe the order and relationship of rock formations, focusing on porphyries, clay-slate, and transitional rocks. It shows how careful noting of position, not just composition, builds a picture of Earth's history across hemispheres.
- How porphyries and clay-slate relate in different regions, including Mexico and Europe.
- Examples of rock notations and how simple symbols can describe complex formations.
- Regional case studies, such as Guanaxuato and the Hungarian rock districts, with practical observations.
- A framework for thinking about earth layers across primitive, intermediary, secondary, and tertiary formations.
Ideal for readers of geology, history of science, and anyone curious about how field observations shape our understanding of the planet.

Book Description
The explorer and multi-disciplinary scientist Alexander von Humboldt (1769-1859) developed some of the first geological theories of continental drift. In this work, translated from the French in 1823, Humboldt uses his field notes to collate his research on geological formations worldwide and their effects on local organic growth.
