Timeframe for Martian crust evolution⁶⁶. Displayed are details of knowledge about the history of NWA 7034/7533 and paired stones. The igneous crystallization of NWA7034/7533 zircons and clasts are derived from McCubbin et al.¹⁷, Humayun et al.³⁶, Nyquist et al.⁶⁷, Tartèse et al.⁶⁸, and Yin et al⁶⁹. Metamorphism and alteration ages are from McCubbin et al.¹⁷, Cassata et al.³⁰, Humayun et al.³⁶, Liu et al.³⁹, Cartwright et al.⁴³, Tartèse et al.⁶⁸, and Lindsay et al.⁷⁰. Brecciation age range is from Cassata et al.³⁰ and Cartwright et al.⁴³, and so is the age of ejection
