This serves as its table of # contents. # Directory of Files A. Petrographic data.xlsx Minerology and mineral modal abundances of studied Isua supracrustal rock samples, obtained from thin section observation. B. Structural data.xlsx Structural and microstructural data of studied Isua supracrustal rock samples. The structural data are from field measurements. The microstructural data are interpreted and/or calculated from thin section observations and/or quartz fabric patterns.
