This research points to heat from the molten rock affecting other sediment in a process called contact metamorphism
, "likely liberating the massive greenhouse gas volumes needed to drive extinction.
2007) and the contact metamorphism

The humite-group minerals have a limited paragenesis and occurs in marbles and skarns generated by contact metamorphism
of the Halifax Formation on the southeastern margin of the Halifax Pluton, Halifax, Nova Scotia.
1983) as a partial resetting of fission-track ages by contact metamorphism
during emplacement of the Hunza Batholith (106-95 Ma, U-Pb zircon age) and also by subsequent Eocene regional metamorphism at the time of the Indo-Eurasian collision.
Massive magnetite (magnetite-quartz rock) is spatially related to remobilisation by contact metamorphism
close to granite / pegmatite intrusives;
Hewitt (1970) argues that the magnetite/silicate mineralization along the quartzite-limestone boundary resulted from a combination of contact metamorphism
and simultaneous hydrothermal activity, and that in the most highly altered zones the original magnesium-rich limestone was wholly replaced by magnetite, staurolite, actinolite.
The settings where magnesite-rich rocks are affected by contact metamorphism
or metasomatism are, therefore, truly rare.
