My name is David Bressan and I'm a freelance geologist working mainly in the Austroalpine crystalline rocks and the South Alpine Palaeozoic and Mesozoic cover-sediments in the Eastern Alps. I graduated with a project on Rock Glaciers dynamics and hydrology, this phase left a special interest for quaternary deposits and modern glacial environments. During my research on glaciers, studying old maps, photography and reports on the former extent of these features, I became interested in history, especially the development of geomorphologic and geological concepts by naturalists and geologists. Living in one of the key area for the history of geology, I combine field trips with the historic research done in these regions, accompanied by historic maps and depictions. I discuss broadly also general geological concepts, especially in glaciology, seismology, volcanology, palaeontology and the relationship of society and geology.

Cabinet of Curiosities #1: All the Wonders of the Net and a Name-Contest

Granite Wars – Episode II: A New Phase (-Diagram)
“Inside the globe [there] exist mysterious forces, whose effects become apparent on the surface. Eruptions of vapors, glowing lava and new volcanic rocks…[]” Alexander von Humboldt At the end of the 19th century and after the victory of “Plutonism” in the great Granite War, geologists accepted the idea that igneous rocks originate from deep inside [...]

Geologizing Asses
“Humanity’s genius is to have always had a sense of its weakness. The physical energy and strength, with which nature insufficiently endowed humans, is found in animals that help them to discover new territories.” “Home” (2009) A post dedicated to the forgotten heroes of early geology - asses !
