      abstract     = {Petrological, palynological and organic-geochemical
                      investigations were undertaken to determine the source
                      vegetation, depositional conditions and hydrocarbon source
                      potential of Eocene Matanomadh lignites from Kutch Basin,
                      western India. The maceral study reveals that studied
                      lignites are rich in huminite (ay. $63\%)$ with sub-ordinate
                      amount of liptinite (ay. $19\%)$ and low inertinite (ay.
                      $3\%),$ along with low to moderately high associated mineral
                      matters (ay. $15\%).$ The overall petrographic composition
                      points to a lagoonal condition for the formation of these
                      lignites. The mean huminite reflectance values (R-r:
                      $0.28-0.34\%,$ ay. $0.31\%)$ as well as low Rock-Eval T-max
                      (av. 417 degrees C) values for the seams, suggest brown coal
                      or lignitic stage/rank for the studied lignites. The
                      palynological assemblages, dominated by tropical
                      angiospermic pollen, suggest prevalence of warm humid
                      tropical climate during the deposition of these lignites.The
                      total organic carbon (TOC) content of lignites ranges
                      between 26 and 58 $wt.\%,$ whereas the TOC content of the
                      associated carbonaceous shales is around 4 $wt.\%.$ The
                      Hydrogen Index (HI) ranging from 23 to 452 mg HC/g TOC
                      indicates that the lignite sequence has the potential to
                      produce mixed oil and gaseous hydrocarbons on maturation.
                      The major pyrolysis products of lignites, derived from Curie
                      point pyrolysis-GC-MS, are straight chain aliphatics,
                      phenols and cadalene-based C-15 bicyclic sesquiterpenoids.
                      The exclusive occurrence of C-15 bicyclic sesquiterpenoids
                      suggests that these compounds are derived from dammar resin
                      of angiosperm plants, belonging to family Dipterocarpaceae.
