MFR6AP3: Imayoshiite with Sphalerite, Tobermorite (Group) and Calcite

One of the best, if not the best, Imayoshiite of very large size, coming from the 2021 finds that yielded the best known so far for the species. On a good size group of very lustrous twinned Sphalerite crystals several Calcite crystals with dominant scalenohedral forms have been precipitated and then were in turn covered almost entirely by whitish Tobermorite-Clinotobermorite crystals and, finally, a large quantity of Imayoshiite crystals of a pale cream color. Thanks to three "windows" in the Calcite crystals we can see the whole process of formation. This very "geological" specimen has been analyzed and we will send a copy of the analysis to the buyer. To learn more about this species and the rest of the paragenesis discovered so far in this mine it is essential to read the article ‘Rare Borate Minerals from the Shijiangshan-Shalonggou Deposits, Hexigten Banner, Inner Mongolia, China', whose authors are César Menor-Salván, Berthold Ottens and Ed Richard, featured in Rocks & Minerals, September/October 2021, volume 96, number 5
