Several thousand specimens of japanese law twin quartz, up to 25 cm large, were uncovered by the company Tropic Stone SARL, from june 2000 to february 2001 in a breccia complex, north of the village of Andilamena, north of Ambatondrazaka. The mineralization is linked to a hydrothermal acitivity associated with tectonics in a metamorfic conext (Forner et al 2001).
