Re: [meteorite-list] Chips Off an Old Lava Flow (Lunar Meteorite Kalahari 009)

I was finally able to put a finger on what has been bothering me with the most recent press release about Kalahari 009. I do not see how it can be called a Mare basalt. Everything I have read suggests that Mare Basalts can be no older than 3.9 billion years. Kalahari 009's 4.35 billion year old
