Fig. 1
Location of the Lijiang-Xiaojinhe fault, southeastern Tibet. The red dots denote earthquakes, and the size of red dots denotes magnitude. The sample site is indicated by a black star.
Fig. 2
Global (1) and detailed (2) views of the sampling area. Picture (3) is the photo of carbonates sample with indication of the sampling point (red square) on picture (1). Area A: milky white and be melted again thoroughly; area B: yellow-white and be partially melted; area C: grey-green and has not the characteristic of being melted.

Fig. 5
Natural ESR spectra of LX samples (part A, B and C). Mn2+-3 at g=2.0345 and Mn2+-4 at g=1.9804 are two of the six main peaks of the Mn2+ ESR spectrum in calcite.
