Respected Dr Christian,

I am really thankful for your reply.  I have gone through this book, not so in detail. I will read in detail now.

Actually i am finding problem to pin point the the area/environment for whole Formation/Unit.

How we can demark for individual units.. i.e Sandstone Unit, Sandy Limestone Unit, Shaly/Silty sandstone unit. (they all are calcareous)

Please i will be really thankful if you can suggest me some research papers (facies, environment for mixed carbonate, or models for mix), to help me broaden my view.

Respected Dr Christian,

Flügel E (2004) Microfacies of carbonate rocks, is really something worth reading. I have started it. 

I will also go through this paper. 

You are right, i have to look for other details, such as, lithofacies distribution, paleo-geological and geographical history of region/area. I have just started from the very beginning. I hope i will end to something good.

As for wells, i do not have well data for this area. My section lies on thrust (Himalayan Frontal Thrust) while nearest well is somewhat 30 km away. Can i use, or collaborate well data so far away from section? 

Dear Mr. Nisar,

the textbook of Flügel is certainly a good choice to get an overview of various (micro)facies types. I know the book and the course. To provide you with some papers on this issue more proximal to your study area, please find the list of publications below:

Der Nisar,

I totally agree with all useful remarks suggestions and bibliographic list provided by Dr. André, Dill and Nyhuis.

Just, I would like to draw your attention that more than one representative section is needed before trying any reconstruction of a depositional model. This should give an idea about not only the vertical stacking pattern of the rocks andbut also on lateral facies changes in at least in proximal and distal settings. The internal architecture of the sedimentary record especially the associated remarkable surfaces indicating major change in depositional environments through time (TS, MFS, etc...) has to be built using different sections.

In addition, the lateral distribution of the siliciclastic material may help in detecting high frequency sea level fluctuations or climatic changes

Good Luck

Dear Nisar,

In addition to all the useful suggestions above, I would like to suggest you to pay a bit more attention to field sedimentary structures and textures, which could be indicative on depositional processes and paleocurrent direction etc. These data could be important for environmental interpretation. 

Good luck and all the best,

Min Zeng

Respected Dr. Harald G. Dill, i am really thankful for your reference list. I will try to go through all of them. Thanks again

Respected Dr. André Klicpera, Your work is really worth reading. Thanks for your kind response.

Respected Dr. Mohamed Soussi , i have two sections measured by myself and there are almost 4 different previous reported sections at different localities (with in 50 to 60 km area). Can i combine previous work in my work? 

Dr, can you please explain little bit how "the lateral distribution of the siliciclastic material may help in detecting high frequency sea level fluctuations or climatic changes" ... plz can you suggest any reference. I really want to read about this. I will be thankful to your kind favor. 

 Respected Dr, Min Zeng, thanks for your kind and helpful comment. I am really having very much difficulty in implementing different sedimentary structures to respective environments. Can you please give some reference for interpreting environment from Sedimentary structures for mixed Carbonates? For the same reason i have uploaded some sedi. Structural field photo with my question. Dr. Min can you please help me little bit in this regard. I will be very thankful to you.

Dear Nizar

The following refrence may help you in your task

Dear Nizar,

Sorry, I really could not get much information from your field photos. The sediments seem to be intensively bioturbated. However, trace fossils appear interesting and I would suggest you take a look at the book:

Seilacher A. Trace fossil analysis. Springer Science & Business Media, 2007.

In addition, stacking pattern of your facies could also be vital. You may have to look at the rocks again in the field.

Good luck.

Dear Nisar,

maybe these two papers can help you about the interaction between carbonate and siliciclastic sediments, and the construction of a depositional model.

I hope to be helpful.
