I am working on Permian glacial sediments in Australia. Recently, I described diamictites, glaciofluvial sands and glaciolacustrine rhythmites mainly from cores. Glacial diamictites in core are very poorly sorted, matrix-or grain supported. The drilling may penetrate large boulders of any rock type that appear different from the overlying and underlying materials. Glaciofluvial and glaciolacustrine sediments are the products of ice melting that always show primary sedimentary structures during transportation and deposition. These sediments consist of moderately to well sorted sands, silts and clays with flat, graded, cross-bedding and lamination. Rhythmites and varves consists of rhythmic alternation if silt, clays and fine sands which forms in glacial lakes.

I will try to send you some photos later on   

Dear Dr. Sultan-Al-Islam,

there are numerous textbooks on sedimentology from Reading via Selley to Miall which summarize the criteria for glacial and fluvio-glacial deposits. I put both types side-by-side with each other.

Diamictite and reworked sediment are the key of glacia deposit. On fluvial glacial normally you encountered sand package with similar characteristic of braid deposit, with a blocky motif on the core Gamma.  These sandstones are sometimes have pebbly layers of different origin which are  easily detected from the core as they show gradation. I also agree with Walid Salama comments

Thanks many Walid Salama, Herald G Dill and Asia Al Rawahi for all of your comments. I shall be happy to receive photograps of Diamictite from Walid Salama

Dear Prof. Ul-Islam,

Please find attached the photos I mentioned before. I made a figure of all types of glacial sediments. 

Best regards

Walid

Thank you Prof. Walid Salama for providing photographs of glacial and fluvioglacial deposits. It will be helpful for me. I shall send you my photographs to have your comments.

Dear Sir,

Surface texture studies will also throw light on such differentiation.
