Köppen climate type:
Occurrences of excellent large babingtonite crystals and other minerals in cavities of Emeishan flood basalts, which cover large parts of southern Sichuan and northeastern Yunnan provinces. A productive zone with large vugs extends for many kilometers along the Yangtze river in Qiaojia County, and similar occurrences are also found at many places in neighbouring Sichuan Province. The localities actually consist of small excavations that were mostly made by collectors.
Recent rumors have suggested that the mineral is not true babingtonite, but is its manganese analog. However, that rumor seems to have no basis. For instance, studies of babingtonites collected from basalt outcrops in Meigu County of Sichuan Province revealed only minor manganese contents in the order of 2-3% MnO (see: http://www.mindat.org/loc-195073.html).

These micro crystals match the epidote shown in Goldschmidt's Atlas der Kristallformen Figure 130 of Band 3, Tafel 126 - page 128 of the mindat scan file, shows the forms very well, especially the T, n and M faces. References: |
