Geochemistery of late Neoproterozoic Cap Carbonate from Banded Iron-formation In the Rizu seri (Zarand) of Kerman
|Location||The 25 Symposium of Geosciences|

Cap carbonates carbon isotope (13c) and Banded Iron formations are the basic events during global glaciations. In the study area. The variety of carbonates include medium to coarse (saddle dolomite ) grains of dolomites, are situated uppermost of sequence of Rizu Formation.
The sequence of Rizu seri Contains of vary lithology, Quartzite sandstone, Turbidite ( graywake) with association of ore minerals(magnetite- hematite- Jasper) , in form of Banded Iron- Formations, (BIFs) .
The existence of dropstones with hetrogenous grains (diamictite) within Fine matrix of carbonate are the indicators for glaciation episodes.
Chemical analyses showed that the
