Karlsbad Sprudelstein
Karlsbad Sprudelstein is a rare sedimentary rock with ‘ooids’ made of aragonite. Ooids are coated grains, where concentric thin layers of the carbonate aragonite, deposited by hot waters, are progressively accreted on a sand grain. This rock is just fantastic under the microscope. Sample provided by Axel Munnecke. (Nikon D810 on Zeiss Axioscop 40 pol.  Transmitted polarised light, Crossed polarisers plus red tint plate. Objective 5x (width c. 5 mm), Sample: 30-micron glass-covered thin section of rock)
