Rock samples from Meetha Nala and Melville Point sections of the Havelock
Island were 'chemically analysed for diatoms. Melville Point Section is represented by Long
and Guitar fonnations while Inglis Formation is exposed in MeeUm Nala Section. Diatoms
have been recovered from Long and Inglis f0l111ations.Siliceous microfossils are absent in
the Guitar Fonnation. Silicoflagellates, radiolarians and sponge spicules are also present in
some samples. A Miocene age is assigned to the diatom assemblage from Havelock. EDAX
of selected rock chips from Havelock was carried out. Samples from Little Andaman are
barren of diatoms. Preparation of a draft manuscript on the stratigraphy of Car Nicobar
Island has been taken up.

Programme 4.5 Palaeogene-Neogene phytoplankton biostratigraphy and
palaeoceanographic set-up of Kutch and Saurashtra basins,
India
Objective To study dinoflagellate cyst morphology and biostratigraphy
and to document phytoplankton rich levels
To intefl,ra/e dinoflagellate cyst, calcareous nannoplankton
and palaeontological data for stratigraphic precision
To document palaeoenvironmental
events
Crucial phytoplankton productive levels have been discovered within the pre-nummulitic
shale sequence (Naredi-Harudi Formation) overlying the Deccan Traps. Study of
dinoflagellate cyst assemblage is in progress.

Programme 5.l Palaeozoic flora of Kashmir region : biozonation, affinities
and biogeography
Objective To make extensive collections of plant fossils from the peri-
Gondwana stratigraphical sequences. their identification and
comparison with Gondwana, Cathaysian and Angaran elements
to trace their origin
More specimens of Kawaziophyllum collected from the Dunpathri Member ofMamal
Fonnation were cleaned, photographed and processed for recovery of the cuticle. No
cuticle was recovered and as such only morphological characters have been considered for
