The "most primitive basalts". Are these merely the oldest? or is there something primitive about these basalts?--Wetman (talk) 01:43, 26 April 2009 (UTC)
They are primitive because nearly all magmas and lavas come from the same source material: mantleperidotite and then evolves into basalt, rhyolite, granite or whatever.. Maybe it should be clarified in the article.Dentren | Talk 15:52, 27 April 2009 (UTC)
I fixed a couple of typos above, but I didn't like to change the wording - however 'evolves' is probably not the right word, try Igneous differentiation.
The picture of the eruption has a link to the Great Chilean Earthquake, which then redirects to 1960 Valdivia earthquake page. I think it would be better to just change the link to 1960 Valdivia earthquake but I am not good with editing and will leave it up to another user. —Preceding unsigned comment added by Usernametakenalready7658 (talk • contribs) 08:50, 5 September 2009 (UTC)
