Abstract
The Habo Dome Sandstone of Chari Formation has been analyzed for petrofacies and diagenetic history. The sandstones are generally medium to coarse grained and moderately to well sorted. These sandstones are composed of several varieties of quartz, feldspar, rock fragments, micas and a suit of heavy minerals derived from the Aravalli Range and Nagarparkar massif. The petrofacies analysis reveals that these sandstones belong to the continental block, recycled orogen and rifted continental margin tectonic regime.
During mechanical compaction rearrangement of grains took place and point and long contacts were formed. The sandstones were cemented by calcite, iron oxide, silica, chalcedony and glauconite cements in order of abundance. Different graphs of porosity versus depth suggest a depth of burial in the range of 615 to 769m.
