Evidence for rapid displacement on Himalayan normal faults and the importance of tectonic denudation in the evolution of mountain ranges: comments and reply
Article Abstract:
K. Hodges et al were able to provide substantial information for the rapid displacement on Himalayan normal faults in their description of the Qomolangma detachment seen along the walls of the Rongbuk Valley, north of Mount Everest. The authors utilized binocular reconnaissance, aerial photographs and radar imaging results in proving their claim on the detachment extending to the Mount Everest massif. Also, previous studies presented by noted geologists studying the mountain were used as the basis of the research.

New constraints on the age of the Manaslu leucogranite: evidence for episodic tectonic denudation in the central Himalaya: comment and reply
Article Abstract:
Previous efforts to date the Manaslu granite and tectonic features in the central Himalayas have been hampered by factors such as minerals' low abundances, inheritance and isotopic disequilibrium as well as the presence of extreme isotopic heterogeneity and the lack of igneous hornblende. A recent study used argon dating on hornblendes that grew in the Manaslu thermal aureole to circumvent the latter limitation. However, the study underestimates age uncertainty by at least a factor of five.

New constraints on the age of the Manaslu leucogranite: evidence for episodic tectonic denudation in the central Himalaya: comment and reply
Article Abstract:
A recent study has been criticized for underestimating age uncertainties of Manaslu granite. However, regression analyses using data-reduction software and a statistical program reveal that there is no statistical basis for questioning the significance of the data presented in the study. Moreover, further research discloses that the study's estimates of the minimum ages of plutons may be closer to the actual crystallization age.
