Perseverance rover on Mars spotted a strange striped rock in Jezero Crater that has planetary scientists discussing its origins.
Boudinage
Boudinage are one of the most spectacular geologic structures and some of my favorite rocks. The boudins are the eye-shaped lenses of rock wedged between the white quartz layers. Find out how they formed below.

"Boudinage" is my favorite geology word
The current edition of the Accretionary Wedge geology blog carnival (hosted by Evelyn Mervine of Georneys) is built around the theme of favorite geology words. My favorite geology word is derived from the French boudin, for sausage. It’s “boudinage,” and it’s best said with a heavy French accent and a leering, dirty expression. “Boo-din-ahhdj” I love pronouncing it; it’s a delicious word, like a good boudin itself. So what is …
