Anyone know of software for Identifying minerals by chemistry?

Years ago I had a DOS program where I could enter a number of elements or radicals, and the program would tell me all the minerals that contained those elements. Does anyone know of any similar, but current, PC software that is available out there? Freeware would be ideal.

Stuart,

Perfect! Why didn't I think of looking for it in Mindat? I've been working on some Cu, Al, S, and O, minerals from the Grandview Mine in Arizona recently, so I used that for a quick test. It not only found cyanotrichite, and carbonate-cyanotrichite, but also found the recently published Grandviewite! Many thanks for your help Stuart.

MDI-Mineral also has a element search - free download.

MinIdent-Win is another excellent program - it's in the $300 range.

I hope I am not out of line here. The MinSearch program on the CD in the back of my book, "Mineral Identification . . ." (Miralogical Record Book Store) searches up to five ions in any combination.
