element - what is the metal distribution in our universe

From the big bang nucleosynthesis (BBN) page is a handy chart of the sources of elements:

Since basically all metals come from some stellar process, the question of elemental distribution can vary greatly between different environments depending on when you're observing that particular galaxy, star/galaxy cluster, etc. Galaxy mergers, supernova, and stellar winds can be particularly good at moving metals around a galaxy or galaxy cluster.



Interestingly Wolfram has element data with Universe abundances but I'm not sure where they derive those.
