Summary of Curiosity Radiometric and Cosmic-Ray Exposure Age Experiments

Location Aliquot Radiometric age (Ma) CRE age (Ma) Interpretation
Cumberland   4210 ± 350 (8.3%) 78 ± 6 (7.7%) Crystallization age of detrital minerals from basaltic precursor; mm to cm/Ma denudation by scarp retreat
Windjana Aliquot 1 627 ± 50 (8.0%) 145 ± 203 (140%) Radiometric ages inaccurate due to incomplete degassing and/or mineralogic fractionation during sample handling
Aliquot 2 1710 ± 110 (6.4%)
Mojave 2 Plagioclase 4070 ± 630 (16%) 300 (36Ar) to 1000 (3He) Crystallization age of detrital minerals from basaltic precusor; pre-burial exposure
Jarosite 2120 ± 360 (17%) Fluid flow through the Murray bedrock

Ma, millions of years before present.
