In the following paragraph, did you intend to use famous rather than infamous?

Katophorite minerals are normally found in alkaline intrusions, such as nepheline syenites and also lamproites and similar rocks, typically together with other Sodium and Calcium bearing amphiboles. The Khibina massif in Russia is infamous in this respect, as 25 different amphiboles has been identified there.

Keith, given the difficulties of identifying amphiboles, I would say that any place with 25 different species will cause so many headaches to collectors that infamous is indeed the appropriate word :-)
