Abstract
This work, based on sedimentological data collected from two stratigra phic sections at Lambar and Malvat (Banihal area), reports the turbidi te to storm influenced sedimentation of ''Syringothyris Limestone'' se quence, Kashmir Himalaya. An upward progresssion of the sequence refle cts the depositional record of fine grained turbidite to storm - and w ave - influenced sedimentation. Sedimentary structures like short wave length symmetrical ripples, flat lamination, thin graded bedding and structures in muddy siltstones suggest deposition in low energy, wave influenced settings. The storm influenced sediments display hummocky c ross stratification, skolithos ichinofacies, granule/shelly lags, mega ripples, low angle cross lamination and convolute lamination. The who le sequence is interpreted to represent episodic storm influenced sedi mentation in a shallow basin, largely controlled by tectonic activity. The Markov Chain models structured for this sequence also suggest epi sodic sedimentation and do not show any cyclicity.
