June 6, 1944 – in planning for D-Day – also geology was considered, as aerial photographs of the shores of Normandy were studied to find suitable landing sites for the invasion.
During the 19th century geologists realized that earth was quite older than previously believed, however this discovery posed an even greater question: what about the universe? Did earth (like some fundamental creationists believed and still believe) predate the cosmos, were earth and the cosmos created at the same time or came earth later?
September 7, marks the anniversary of the publication of an important paper, “Magnetic Anomalies Over Oceanic Ridges” (1964) describes the discovery of parallel stripes of magnetized igneous rocks along the ocean floor.
“Every one has heard of the Ibis, the bird to which the ancient Egyptians paid religious worship; which they brought up in the interior of their temples, which they allowed to stray unharmed trough their cities, and whose murderer, even though involuntary, was pnished by death; which they embalmed with as much care as their [...]
Sometimes a geological map supports an intriguing idea not by showing the rocks that are there, but by showing the rocks that aren’t there anymore, eroded by a flood of biblical proportions.
March 23, 1769 marks the birthday of pioneering stratigrapher William Smith, who is also credited with creating the first useful geological map, however like many other great accomplishments also Smith’s idea of depicting the distribution of rocks on a topographic map didn’t materialize out of nowhere.
The German lawyer, author, poet, politician and artist Johann Wolfgang von Goethe (born August 28, 1749-1832) was also a mining engineer and quite interested in geology and paleontology.
“the magisterium, our great work, the stone” “The Alchemist” Act 1. Scene 4 4. – The Philosopher’s Stone Today we remember Sir Isaac Newton (1642-1727) for his contributions to optics, mechanics and astronomy, but as a typical scholar of his time he was also interested in more obscure knowledge, like provided by alchemy.
In 1820 the Italian engineer Count Giuseppe Marzari-Pencati (1779-1836) published a short article about the stratigraphic succession found near the small village of Predazzo.
The first maps used symbols to characterize single outcrops; later maps introduced shaded areas to display the distribution of specific rock-types, but due the high printing-costs these maps were printed only in black & white, making them hard to read.
A video showing the aftermath of a rockfall in South-Tyrol remembers us that even small mass movements can have disastrous – or even deadly – effects.
Alpine-Type Fissures, fissures filled often with large and beautiful crystals of Quartz, Plagioclase, Rutile , Amphibole and even Gold, are – according to Alpine folklore the treasure chambers of dwarves – but how these treasures formed is even more fascinating than legends could figure out… Soon after the basic principles of the succession of rocks [...]
U.S.G.S. engineer Bailey Willis ( February 19, 1949) was known for his unorthodox approach to geological questions. Puzzled by the geological structures he discovered in mountain ranges, long before computer-models were available, he constructed a machine to simulate the mountain-forming process.
