NW Himalaya differs largely from the central Nepal sector, for which plenty of cross-sections are available. I am in search of newly published generalised one.
Crustal shortening along strike in Himalayan orogen differs considerably from west to the east. Moreover, the back thrusts, lateral ramps , window zones etc. are characteristics of many regions. I think, it would be difficult to consider a section as ideal for any broad segment (say western or central ) of Himalaya.
There was one published in the last year or two. I'd not sure which publication but, since it was one I had a physical copy of, it was either Geology, AAAS, or Nature Geoscience. You could do an advanced search using each of those terms and stipulating the journal name.
Please find the cross sections in District resource maps published by Geological Survey of India. You can procure data for required area from GSI. They have mapped Major Structural formations like anticlines, synclines and Faults in the Entire Himalayas. As the geological structures are regional the maps are published in 1:250,000 scale and 1deg*1deg area covered in 1 Sheet.
