The Zonuz irregular lens shaped kaolin deposit located
in Marand, Azarbaygan, is exploited as an openpit. Andesite,
Trachyandesite and dacite igneous rocks are located in south, west
and east parts of the deposit, respectively. The Ore was analysed
by XRD, SEM and NAA. Assemblage of major minerals including
Quartz, Kaolinite, Illite and Calcite, and minor minerals of
Dolomite, Montmorillonite and Limonite are detected.
Geochemical analysis show that La, Ce, Nd are present in minor
amounts, and the high ratio of LREEIHREE indicates the
enrichment of LREE which is probably the result of surface
tension ofthese elements on clay particles.
Geological and Geochemical evidence indicate that hydrothermal
fluids played a major role in the formation of the Ore body,
particulary along fault zones.
A comparison is also made between autogentic Zonuz deposit with
allogentic Esteghlal deposit.
