That (second) paper, at https://www.degruyter.com/document/doi/10.2138/am-2015-5061/html https://www.degruyter.com/document/doi/10.2138/am-2015-5061/... , says: > Here we report the characteristics of terrestrial tetrataenite from an ophiolite-hosted Ni-bearing magnetite body from the Indo-Myanmar ranges, northeast India. Although the mineral assemblage surrounding it is very similar to that found in the meteorites, the postulated cooling regimes cannot be similar. The mineral is formed as a consequence of hydrothermal alteration of ferromagnesian minerals of the olivine and pyroxene groups.
