Identity HelpUnknown creamy white mineral with vauxite from Bolivia
Hello, can anyone offer suggestions what the creamy white mineral is with my vauxite specimen which I got today. It's from the type locality for vauxite, Siglo Veinte Mine (Siglo XX Mine; Llallagua Mine; Catavi), Llallagua, Rafael Bustillo Province (Bustillos Province), Potosí Department, Bolivia
My initial guess was allophane, then someone mentioned it could possibly be paravauxite (that would be nice!) Whilst looking at photos of paravauxite i could not see many similarities but did notice some specimens have wavellite and that looks a little more like what I have.
Thanks
Jason
Hello,
looks like Crandallite

Thank you Gunnar and Rock, I see crandalite is listed at that locality but there are no photos to compare it to. I shall look at crandalite from other localities. I can see where you are coming from Gunnar, I even noticed a variety of crandalite referred to as pseudocrandalite. I can't tell what the white crust is from the photo, not without a much more detailed close-up, but for white crusts from this locality: paravauxite, wavellite, variscite, allophane, "phosphate-allophane", and possibly others are all possible, with wavellite being (by far) the most common of the lot and therefore the most likely (in the absence of analyses to the contrary). The crandallites I've seen from here were more beige or brownish than white, although I can't say white ones couldn't exist.
