System:AmorphousColour:Yellow to ...
Hardness:3 - 4
Name:Named in 1837 by Johann Friedric August Breithaupt from the Greek διάδοχος for "successor," presumably in allusion to its secondary origin.


Similar to Destinezite, with which it was often confused, until destinezite was (re)defined as the crystalline equivalent of the amorphous diadochite. (IMA decision 00-E)

A secondary mineral occurring in gossans and coal deposits as the result of sulfate-rich solutions reacting with earlier phosphates; common in secondary phosphate assemblages in granitic pegmatites; in cave deposits, or as a post-mining product.
