Petrophysical data for 29 samples from the Chicxulub impact crater.

Note: ɸ-porosity, ρb-bulk density, ρg-grain density, k-permeability, F-formation factor, m-cementation exponent, τ2-tortuosity, Cs-surface conductivity, Vp-acoustic velocity of compressional waves. Uncertainty for porosity, density, permeability, velocity and conductivity is 5%. Uncertainty for formation factor, cementation exponent and tortuosity is 8%). Lith 1 and Unit 1 after Morgan et al. (2017), Unit 2 after de Graaf et al. (2021, UIM-upper impact melt rock unit, LIMB-lower impact melt rock-bearing unit)) and Kaskes et al. (2021).
