Dear all, Some years ago, the mineral zircon was encountered in a hydrothermal environment. Some people considered those zircons not to be "endemic" to that environment. Has zircon been confirmed as a mineral that forms from scratch in a hydrothermal environment? If so, can anyone share the earliest reference(s) on hydrothermally formed zircon? Looking FW to your replies! Meanwhile, the very best for 2025 to all! Cheers, Herwig

Hi Herwig, Happy New Year!

Gentlepeople, I apologize for the belated reply; quite a few people sent me direct messages with lots of interesting references, so it took me a while to process them. Thanks to all who reacted, highly appreciated. In return, I can provide you with a link to a recent article, written by Olav Revheim, and published on the mindat website: https://www.mindat.org/article.php/5014/Hydrothermal+zircon+from+the+Mount+Rosa+Complex%2C+Colorado%2C+USA Enjoy the read!
