Formula:
Zn, Fe, As, O, H
Colour:
Green
Lustre:
Resinous
Some samples appear to be an amorphous Zn-Fe-arsenate, others fahleite ("In June of 1997, I ran EDS on several samples of GS1 in my lab, finding it to be a Zn-Ca-Fe arsenate. A sample was sent to Andy Roberts at the Geological Survey of Canada for XRD work. Running overnight in a Debye-Scherrer camera with subsequent indexing by Andy pointed to fahleite, and the film is probably still on file there under its ID number of X-77877. That is not to say more work isn't needed, or that all samples of GS-1 are fahleite, but some of it certainly is, based on chemistry and XRD work.", Tony Nikischer in http://www.mindat.org/mesg-14-207138.html ).
