Supplementary Material FOR Coesite-bearing microdiamonds in dolerite from mantle plume derived large igneous province

Supplementary Material data to this article including Supplementary Figures, Supplementary Tables and Supplementary Note about crustal contamination, alteration and fractional crystallization effect of diamond-bearing dolerites. Supplementary Figures including filed outcrop, photomicrographs, geochemical discrimination, magma fractionation, crustal contamination effect of the diamond-bearing dolerites; Supplementary Tables 1-3 including corresponding geochemical, zircon chronology data of the diamond-bearing dolerites, and the major FTIR peaks and nitrogen contents of microdiamonds from dolerites. FTIR and Raman raw data is provided as individual file in Supplementary Table 4 and 5.
