... the Lengenbach quarry, by far the most prolific Swiss type-locality. Canton Grisons is a distant second, with six type-localities from which 13 new species have been described, 10 of these from the Mn-bearing orebodies represented by Falotta (3), Parsettens (4) and Fianel (3) type-localities. The most productive...
