Fourteen histograms showing per cent frequency of palynotaxa at generic level in
different palyniferous horizons of the Ihuran and Bhuj formations, and a distribution plot of
selected palynospecies were prepared for the final report on the ONGC funded project
"Palynology of the Mesozoic sedimentaries of the Kutch Basin". Data available so far indicate
that the Middle Member of the fuuran Formation may not be older than Late Tithonian
in age.
H.K. Maheshwari & B.N . .lana
The report ofONGC-BSIP's collaborative Project entitled "Palynology of the Mesozoic
sediments of Kutch Basin" was finalized for submission.
In addition to the study of calcareous algae of Bagh beds, a study of the algal flora
found in Sylhet Limestone Formation of Meghalaya was canied out. The assemblage contains
Lithothamnium, Distichoplax, Archaeolithothamnium, etc.

Chemical processing of bore-hole samples (45) of Narakal, Turavur and Cherai of
Ernakulam District provided by Central Ground Water Board, TrivandlUm, Kerala were
completed. Slides were prepared for the productive samples.

A rich pteridophytic spore ~ssemblage has been recorded from the rock samples
collected fi·om Dharamshala Formation near Bilaspur, Himachal Pradesh.

Extant pollen grains of the families Alangiaceae, Arecaceae, Araceae, Liliaceae,
Bombacaceae, Euphorbiaceae and Rubiaceae were studied at French Institute, PondichelTY·

Scanning electron microscopical observations on few pollen were made which are
commonly met in the Tertiary sediments oflndia. A new genus - Piladiporopollenites was
instituted.

Pollen analysed two soil samples received from Professor (Ms) S. Sachi Devi,
Department of Geography, Andlu·a University, Vishakhapatnam (Consultancy Service). The
palynoassemblage of the sample from Bukkapatnam tank has revealed that there had been
sea influence at the site from where the sample is collected. This feature is exemplified by
the preponderance of Sonneratia pollen grains to the tune of 80 per cent of the total vegetation.
The other sample revealed the absence of biota indicative of oxidising environment.
