A systematic finite strain measurement using the R_f/φ method has been conducted throughout the Guposhan-Huashan granitic batholith and its thermal contact metamorphic country rocks, for a total number of 15 000 strain markers at 153 field stations. The results show that: 1) the country rocks and early emplaced intrusions and intrusive units such as the Niumiao and Yangmeishan intrusions, and Lisong and Wanggao units are dominantly characterized by flattening strain, whereas the late emplaced Xinlu unit by constrictional strain; 2) the mean strain intensities and compression rates of the batholith are less than that of the country rocks; and 3) within the country rocks, the long axes of strain ellipsoids, measured adjacent to the batholith contact and at the border of each intrusive unit, are mostly parallel to the contact surface.
