Talk:Cumberlandite

Cumberlandite is considered a rock, not a mineral, and as such should not link to the Mineral Pages. Garybrennan (talk) 04:33, 29 March 2009 (UTC)

How does this differ from just porphyritic basalt?
wondering what makes cumberlandite different or special? 140.194.40.57 (talk) 14:08, 6 February 2024 (UTC)
