Extract from Legend to "Geologic Map of Bhutan" (Long, S., McQuarrie, N., et al., 2011, Journal of Maps). Age spans estimated from correlation diagrams in Martin, A.J. (2017, "A review of Himalayan stratigraphy, magmatism, and structure", Gondwana Research, 49: 42-80; http://dx.doi.org/10.1016/j.gr.2017.04.031), but these are often controversial.
