A brief account of these works is as follows:
I. PALYNOLOGICAL,
BIOSTRATIGRAPHICAL AND
PALAEOENVIRONMENTAL STUDIES:
A. Meghalaya Basin and Arunachal Himalayas: Lithostratigraphy and biostratigraphic
works based on palynological studies on Palaeocene–Eocene sediments exposed in Jaintia
Hills, East Garo Hills and West Garo Hills, Meghalaya were done. Palynofossils from the
Tertiary deposits of Kameng, Subansiri and Siang districts, Arunanchal Pradesh were studied.
These investigations confirmed the presence of Late Eocene deposits in Eastern Himalayas.
B. Siwalik sediments of Jammu and Kashmir: Palynological and sedimentological studies
from Lower and middle Siwalik sediments exposed near Nandni in Jammu were carried out
with a view to determine the vegetation and climate of the area at the time of deposition.
C. Andaman and Nicobar Basin: Three road sections of Middle Andaman viz., Chainpur,
Kalunala and Lipak were investigated palynologically. Several levels of these sections proved
productive yielding terrestrial palynofossils and dinoflagellate cysts of Late Cretaceous and
late Eocene-Oligocene ages. Reworked Triassic palynofossils were also recorded.
D. Rajasthan Basin: Early Palaeogene sediments from bore-holes and poen-cast lignite
mines located at different sites at Barmer and Nagaur were investigated. Studies under this
project generated significant information about the vegetation history, biostratigraphy and
palaeoenvironment.
E. Gujarat Basin: Palynological studies were taken up on Early Palaeogene sediments of
Vastan lignite mine, Mangrole lignite mine, Surat and Matanomadh lignite mine, Kutch.
II. WORK ON THE MONOGRAPH
TITLE OF MONOGRAPH – “INDIAN
FOSSIL FUNGI”
Authors - Dr. R.K. Saxena & S.K.M. Tripathi
Critical taxonomic evaluation of fossil fungal remains from India was done. These studies
were aimed at streamlining the prevailing taxonomic chaos in fossil fungal remains. All fossil
fungal taxa known till 2010 were described along with their text figures, taxonomic details
and occurrences in India.
III. WORK ON THE BOOK:
Title of the book – “Seven Decades of Indian Tertiary Spore-Pollen Floras: A
compendium”
Authors - Dr. R.K. Saxena & S.K.M. Tripathi
Day-by-day it was getting difficult and impractical to keep the track of published papers
related with Tertiary palynology (spore/pollen assemblages) and their applications.
Therefore, the need to assemble and collate the contents of these publications at one place
was felt since long. The book provides an abridged version of all till-date publications
pertaining to palynology from Indian sediments along with the Key-words marking the theme
of each contribution.
IV. WORK UNDER SPONSORED PROJECT:
Work under a DST sponsored project “Environment of deposition and biosrtatigraphy of
Early Tertiary lignites of Rajasthan and adjoining areas” was completed (January, 2005
to June, 2008). Under this project Palynological as well as palynofacies studies on samples
representing the Akli Formation of Barmer, Rajasthan, and Cambay Shale of Vastan lignite
mine, Surat, Gujarat were conducted.
V. STUDIES UNDER INTERNATIONAL COLLABORATION:
Joint research programmes were undertaken with a celebrated palynologist Professor Mklos
Kedvs of Plant Cell Biology Unit, Szeged University, Szeged, Hungary. These research
programmes were conducted under the Exchange of Scientists Programme between INSA,
New Delhi and Hungarian Academy of Sciences, Budapest.
Highlights of the works under this programme are as follows:
1. Studies on biopolymer symmetry:
TEM studies were made on partially dissolved fossil and extant pollen walls and cuticles with
an object to observe the relationship between quasi-crystalloid and quasi-periodic structures.
An analogy in structural symmetries between biomolecules of sporopollenin and cutine were
observed. Sporopollenin is a substance, which forms a coating on the walls of spores and
pollen grains whereas, cutine is the coating surface present on different parts of plants. These
substances are quite resistant to destruction or oxidation, a characteristic associated with the
arrangement of molecules within the stable and meta-stable structures. Studies have
suggested common origin of these resistant plant substances. Results of these studies were
published in Hungarian journal.
2. Effect of temperature and organic solvents on pollen morphology:
Pollen grains of twenty Indian Palm species were investigated to observe the effect of
temperature on their morphological features. Pollen grains were subjected to 2000C for 1, 25
and 100 hour(s). As a result to this treatment darkening of colour, increase in exine thickness
and change in equatorial and polar diameter in pollen were noticed. These experimental
studies have proved very helpful in elucidating the post-burial history of organic particles
and have also provided trails for the taxonomic assessment of monocolpate pollen
abundantly occurring in Tertiary sequences of India.
