From: The impact origin and evolution of Chryse Planitia on Mars revealed by buried craters
The estimated thickness of fill based on crater morphometry in the region of Chryse Anomaly unit. a Schematics of the morphological parameters used to calculate fill thickness for partially and completely buried craters. b Geographic locations of the regions for the calculation of impact crater thickness in c, with Mars Bouguer gravity anomaly as the base map20. c Variation of the calculated fill thickness with distance to the center of the anomaly. The colored box indicates the range of values from the lower to upper quartile for each column, with a black horizontal line at the median value. The whiskers extending from the box show the total range of the data, except for outlier points which are indicated using black diamonds
