The potential for Cretaceous coal in Antarctica
Cretaceous sediments in the Antarctic have yielded diverse fossil floras, and a few occurrences of thin coal have been described. Their presence illustrates that the climate was favorable for plant growth, despite Antarctica's polar position, and there was good potential for organic matter accu...
