Sample Unusual Lava Textures in Tharsis Region

Unusual Lava Textures
Most of the flows here look blocky, or like what is called “pahoehoe lava.” This is a common type of basaltic lava that cools down forming typical smooth, billowy, or ropy surfaces. Often, it forms by many small breakouts of lava from an over-crusted inflating flat, irregular flow.
