 There is a statement in https://www.mindat.org/loc-4086.html  that
"Zaratite from Lancaster Co. was proven to be gaspéite." All localities in Lancaster Co.? No reference appears to be cited in support.  If as the statement implies, then zaratite should be removed from the list of mineral species for all Lancaster Co. and the titles for all zaratite photos from Lancaster Co. Pa be retitled as gaspéite? I want to mention that I'm not sure that the statement was intended to mean all zaratites from Lancaster Co. are gaspéites.

who also added a reference which may contain some information:
Garcia-Guinea, J., La Iglesia, A., Crespo-Feo, E., González del Tanago, J., Correcher, V. (2014): The status of zaratite; investigation of the type specimen from Cape Ortegal, Galicia, Spain. European Journal of Mineralogy: 25: 995-1004.

Adding this reference to the Woods Chrome mine main page was a poorly considered choice and is fairly misleading.  This article/abstract questions the validity of Zaratite as a species, due to it's near amorphous nature.  Only a single study sample from Wood Chrome was analyzed and found to be near Gaspietie, which is entirely insufficient to characterize the occurrence there as a whole.  This was an effort to provide good evidence to a make a case that the species may not be well enough defined, or even a valid species.  A good deal of variability is likely to be found in this material variously identified as Zaratite, Genthite, Nickel Gymmite, etc. at Woods Chrome.

My suggestion would be to confine this reference to the Zaratite page alone, until further, more conclusive, work is done on the validity of the species itself.

No response, so rather than remove it all together, I expounded upon this reference on the Wood Chrome page to make the overall issue concerning Zaratite more clear.  

Thanks all.
