Overburden-Induced Flattening Structure in the Himalaya: Mechanism and Implication

Current Science, 2015
Small-scale structures in fold-thrust belt are mainly formed in response to the emplacement of thrust sheets. However, some small-scale structures may not be developed directly in response to the emplacement of thrust sheets, but might be genetically tied with the orogenic process.
