I knew such a text existed, but the reference I had contained a question mark in the title. Now a refined question: At what point are meteorites paired? If a same day fall 50km apart with similar composition is still not enough, then what is? According to the authors, more study is needed. What might that study be? And if such synchronicity is not a preponderance of evidence for pairing, how can any ancient falls on the hot deserts ever be truly paired? Just wondering.
