This one was a better delivery.

Appears to be a gabbro crystallised from an Alkali basalt. This is a classic magma of relatively low supply rate hotspot volcanoes (wierder composition occasionally turns up on Earth such as in the Oslo Graben or E. African Rift).

This is actually quite good news for Martian history given that it has BIG hotspot volcanoes and a very thick crust. With smaller hotspots the result will be occasional cinder cones with Alk Basalr composition.

Have a nice day: Ag
