BSIPand time boundaries: To integrate the diatomestablished foraminiferalstudybiostratigraphy with thebiozones and isotopeStudies on diatoms and silicoflagellates from the 75 meter thick South CoastCliff Section of Kamona Island were continued. SEM photography of selected andstra tigraphically im portant taxa was done for better understanding of the morphology.Middle Miocene age is assigned to this section on the basis of diatom assemblage.Ani!ChandraPROJECT 5 : PALAEO FLORISTIC DIVERSIFICATION INTIlE IIIMALAYAProgramme 5.1 : }")alaeozoic flora of Kashmir regiontion affinities and biogeographybiozona·Objective: To make extensive collections of plant fossils fromthe peri-Gondwana stratigraphiCtlI sequences, theiridentification and comparison with Gondwana, Calhaysian and Angaran elements 10 trace their origin. - ./" ....,.f.,.,·"30'Cockroach' from Mamal Formation(Early Permian), Kashmir.
1991-92A partially preserved cockroach has been recorded from the Mamal Formationof Kashmir Basin. Besides the fore-wings, which are similar to those ofKashmiroblalla Verma, the hind wings, limbs, the head capsule and a part of thepro thorax are also preserved.H.M. Kapoor (Emeritus Scientist), Usha Bajpai and H.K. MaheshwariThe Mamal Formation, uppermost formation of the Panjal Group in Kashmir,has been redefined. The nomenclatural status of the formation is accepted but itsdefinition has been modified on the basis of lithology, relative position of differentbeds and the contained biota. The four beds recognized earlier, viz., Vihi,Marhoma, Munda and Mamal, have been redesigned as Risin, Marhoma, Mundaand Dunpathri Formation taking into account the historical aspects and othercriteria.Programme 5.2 ,Palynofloras of theHimalaya, theirrelationshipH.M.

Maheshwari and Usha BajpaiTethyan sediments of theprovenance and regionalObjective ,To search palynofossils in the well datedof Palaeozoic and Mesozoic sediments(Spiti), Mallo Johar (Kumaon) and(Guryul ravine)sequenceof NitiKashmirThe highly carbonised nature of palynomorphs and their rarity in the samplesavailable poses problems in recovery and morphographic study. However, some ofthe material has yielded good assemblages. Repeated maceration with varied tech·niques proved helpful. Palynomorphs found in Permian section of Rambakot andShal-Shal localities were studied for their detail morphology. Most of the formsare similar to those in the Permian sequence of the peninsula.R.S.
