Abstract:
The Ca-Mg carbonate rocks
of the Deoban - Formation in Kumaun
Lesser Himalaya have been extensively
studied for field, petrography, and
geochemical characters whereby the
dolomitization after calcite precursor is
well established. Many microlithotypes
are identified in them, which are fine
grained and preserve the original organic
and inorganic fabric. Lack of substantial
compaction is evident by the fenestral
structure (Fig.1). Polygonal mud cracks
and parallel lamination in these
carbonates signify their exposure as well
as deposition in a quiet, shallow marine
tidal flat environment. The studies of the
fluid evolved in these carbonates and
circulated in the basin have not been
comprehensive. Present study aims to
understand ,the basinal fluids contributed
in the formation of various lithofacies
from limestone-dolomite-magnesite to
talc. In the present work representative
samples from Jhiroli area in, Kumaun
Lesser Himalaya have been studied.
