When it comes to Biotite, there is probably no significant difference.
With respect to the rest of the weathering complex, I would expect the
two materials to be signifcantly different.

In the same way that I know that I can take a photograph of you from a
distance of 3m which will show every hair on your face and all but the
smallest pores on your skin. I haven't done it yet but I know that I
could if I was given the opportunity. [I would probably choose to use
my Nikon 801S with the 105mm MicroNikor lense at about f16, and with
Fujicolor Superia 200 film in the camera.]

Similarly, while I can think of several laboratory instruments and
techniques which could detect the presence of the chemicals claimed in
the article, I would actually seek the advice of specialists in this
field. I am quite sure that they could identify the presence of the
anomalous materials, right down to the atomic level if necessary.
