Caucasus (Armenia, Azerbaidyan, Georgia)

This is a comprehensive list of alkaline localities in the Causasus states, mostly, but not only (don´t underestimate me !), taken from the Woolley book (see below), generously given to me for 3 months by Peter G.Seroka - many thanks ! Btw - the information not from the book is from P.G.Seroka himself. The mineral lists are certainly incomplete.
