Abstract
The basalt surrounding a tree mould in a flow from Mt. Wellington, Auckland, has been found to contain native iron produced by reduction of ore. Shrinkage cracks in the charcoal within the mould have been invaded by an alkali-rich residuum of the basalt, thus providing a small-scale example of “filter-press” differentiation.Keywords
