Re-Os isochron diagrams for South Australian asphaltites. (A) Regression of all Re-Os data (n = 16) from asphaltite interiors, weathered exteriors and replicate analyses yields an age of 74 ± 26 Ma. (B) Regression of asphaltite data with <2% deviation from the regression of all data points (n = 9; Table S3) yields an age of 68 ± 15 Ma.
