Abstract
After chondritic thermal metamorphism the thermal evolution of a primitive achondritic mineral assemblage continued by partial melting and outflow of the metal-sulfide components and of the low melting point basaltic components. Metal-sulfide assemblage migrated toward the center, basalt migrated toward the surface of the asteroidal parent body. In our paper the HED basaltic achondrites are arranged into a sequence by their increasing SiC>2 content: diogenites, howardites and eucrites. Comparing this sequence with that of terrestrial basalts of komatiites, picrites and tholeiitic basalts we found a similar bulk thermal evolution trend for them. We give an overview about both of these sequences as a long term planetary evolutionary differentiation sequences by inserting them into the thermal evolution of a solid body. General main trends in planetary differentiation are also discussed.
