Some time back I found a very detailed review published in Earth-Science Reviews by An Yin of University of California, Los Angeles. : Cenozoic tectonic evolution of the Himalayan orogen as constrained by along-strike variation of structural geometry, exhumation history, and foreland sedimentation
In it was a map I was looking for.
Source: An Yin 2005
What I liked about it is that it covers the entire length and width of the orogen. The along strike variations in the major tectonic boundaries and stratigraphic units are clarified. Their local names are annotated properly along with the common names for the regions in which these geologic units fall. That is one of the major headaches of understanding Himalayan geology and this map does much to sort through the confusion.
