The study, led by Rice University's Cin-Ty Lee, demonstrates that the southern highlands' thick crust—up to 80 kilometers in some areas—was hot enough during the Noachian and early Hesperian ...

Among these findings, phyllosilicates within the Noachian crust—formed more than 3.8 billion years ago—indicate long-term interactions between water and Martian rocks. Hydrothermal systems may ...
