Achondrite (Planetary science đŸȘ)

An achondrite is a stony meteorite that does not contain chondrules. It consists of material similar to terrestrial basalts or plutonic rocks and has been differentiated and reprocessed to a lesser or greater degree due to melting and recrystallization on or within meteorite parent bodies. As a result, achondrites have distinct textures and mineralog...

4.6-Billion-Year-Old Meteorite Provides New Insights into Early Solar Nebula
Scientists have determined a precise lead isotopic age of the andesitic achondrite meteorite Erg Chech 002. Their result, combined with published aluminum-26-magnesium-26 data for Erg Chech 002 and other achondrites, clearly demonstrates a heterogeneous distribution of aluminum-26 — a major heat source for early planetary melting — in the early Solar Nebula.
