Moldavites are tektites.They are found in the Czech Republic in two
distinct strewn fields,the Bohemian and the Moravian ones.
Their average composition is:
SiO2	71-83%
Al2O3	8-14%
CaO	1.43-5.80%
MgO	1.31-2.52%
Na2O	0.29-0.54%
K2O	2.41-3.72%.
Prof.Bouska has written an excellent book:MOLDAVITES-THE CZECH TEKTITES
(Prague 1994),that is unfortunately sold out.

Best tektitical regards!
