Hi all,
While working with Mixed Carbonate-Clastic successions, how do we mark Sequences and High Resolution Stratigraphy? Any recommendation of reference or research paper will be appreciated.
Thanks,
Haroon
Hi, Syed
I exactly don't know what kind of mixing your sedimentary succession exhibits but in order to have a 'compendium' dealing also on the past literature on mixed (carbonate/siliciclastic) systems and their sequence stratigraphic interpretation, I suggest to take a look to the following papers:

Thanks Sir André Klicpera and Sir Sergio Longhitano for your feedback. My Field area is having more carbonate deposition then compared to clastics. And the grain type for carbonate range from skeletal, oolitic, to stromatolitic. And these shows cyclicity. Sandstone are cross bedded and highly bioturbated.
Sequence stratigraphy concept advocates the interpretation of sedimentary sequence in terms of relative changes in sea level. So Sequance Stratigraphy Integrate time and sea level changes.
The fundamental unit of sequence stratigraphy is Parasequence. Parasequence are composed of laminae, lamina sets, beds and bed sets unit.
Is defining as a relative conformable succession of genetically related succession of beds bounded by marine flooding and their correlatable surfaces.
High Resolution chronostratigraphy A particular parasequence which bounded by significant chronostratigraphically surface that separates all the strata above from all the strata below over extent of the surface. Hence this bounding surface is correlated using well logs, cores or outcrops provide high resolution chronostratigraphy framework for facies analysis.
I highly recommend visiting the Strata web site maintained by SEPM:
http://www.sepmstrata.org
Many/most of the sequence stratigraphy materials and animations available on the site were originally developed by developed by Professor Christopher Kendall (University of South Carolina) and Nassir Al Naji (then a graduate student a USC). You will find info on many topics. Here is link to pages specifically addressing stratigraphy of Mixed Clastic and Carbonate basins:

Hi Syed,
I suggest you take a look on the paper " Orbital-driven cyclicity and the role of halokinesis on accommodation within siliciclastic to carbonate, shallow-water Albian deposits in the Espírito Santo Basin, southeastern Brazil".Cretaceous Research. Volume 35, June 2012, Pages 22–32; DOI: 10.1016/j.cretres.2011.11.008
Besides, you can search for my PhD thesis, which main goal is to define the origin of the carbonate, hybrid and siliciclastic Albian rocks that occur in the Espirito Santo basin, Brazil. Forteen lithofacies were described and organized into eigth facies sucession, whose superposition confirmed an allocyclic nature of the facies succecssion. A depositional/paleoclimate model was proposed to explain the vertical succession of the lithologies within an high-frequency "ideal sedimentary cycle" as well as the regional arrangement of the main lithologies at the 3rd order scale. On its elaboration, both autogenic (terrigenous input delivered to the coast by ephemeral fluvial floods and in situ production of carbonate - oncolites, bioclastics and oolites - particles the redistribution of both by longshore currents and storm events and allogenic (climate changes controlled by orbital cycles) processes were taken into account. The sedimentary succession is organized as high-frequency, 100 Ky cycles (short eccentricity in the Milankovitch scale) forming repeated transgressive-regressive (T – R) cycles. The preservation of the cycicity within the studied section is ascribed to the high siliciclastic sedimentation rate favoring salt escape and increasing accomodation.
Hi, Syed,
Maybe, you can find something useful in one of our articles on mixed sediments.

Hi Syed,
Maybe take a look at the most recent paper from Octavian Catuneanu (2019), Model-independent sequence stratigraphy, in Earth-Science Reviews.
Also, take a look at his researchgate page. Lots of interesting papers on sequence stratigraphy.
Best wishes,
Gilda
