Comment on “Dextral transpression and late-Eocene magmatism in the trans-Himalayan Ladakh Batholith (North India): implications for tectono-magmatic evolution of the Indo-Eurasian collisional arc”
We would like to congratulate Sen and Collins (2012) for producing a detailed study of the structural history of the Ladakh Batholith according to new LA-ICPMS U/Pb analyses of zircon and AMS measurements. This work provides some significant findings to the evolution of this part of the Himalaya. However, we wanted to draw the author’s attention to the omission of a discussion of other geochronological results from the region (White et al. 2012). This is because the results are particularly important for understanding the India–Asia collision. We also raise concerns about some of the conclusions that were drawn from AMS measurement in regard to postcrystallization deformation of the Ladakh Batholith granitoids.
