Geology Word of the Week: H is for Hand Lens

These posts included a brief definition (written by me) of the word and then some additional information and pictures. However, starting in 2012 I stopped posting these words regularly. I was quite busy in 2012 because …

Kolmanskop in Pictures

Kolmanskop was founded shortly after diamonds were discovered in the region in 1908 and was abandoned …

In future posts, I’ll write a little more about the volcanic history of Mauritius. In brief, Mauritius is believed to have been formed by a …
