(乌山锰铝榴石矿, 通北, 云霄县, 漳州市, 福建省, 中国)
The first specimens of chinese garnet associated with smoky quartz and feldspar appeared on the market in 1998. The locality cited was the city of Lechang, in Guangdong Province; only at the end of 2001 some dealers gave the province of Fujian as the true locality and Yunxiao as the nearest large city.
Samples come from two main collecting site: the first lies near the village of Tongbei, 30 km west of Yunxiao; the second is reached from the city of Zhangpu, 30 km northwest, towards Yunling.
At Tongbei it is possible to collect helvite and topaz but not fluorite which is present only at Yunling.
The discovery of these localities took place 15 years ago.
Granitic rocks originated as intrusions during the late Mesozoic, as a result of the subduction of Paleo-Pacific Plate under the continental plate of southeastern China.
