Debaoite

A variety of Parnauite
This page is currently not sponsored. Click here to sponsor this page.
Formula:
Cu9(AsO4)2(SO4)(OH,CO3)10 · 6H2O
Colour:
Jade green to greyish green
Lustre:
Vitreous, Pearly
Hardness:
2
Specific Gravity:
3.33
Name:
For the discovery locality, the Debao ore district of Guangxi, China.
Debaoite was described in 1990 without IMA approval as a new mineral, whose status remained uncertain. It was later recognized as a carbonate-bearing variety of parnauite (the latter may, however, contain carbonate anyway, see there).

Originally reported from Debao (Qinjia) Cu-Sn deposit, Debao Co., Baise Prefecture, Guangxi Zhuang Autonomous Region, China.
