The hydration of basaltic glass to form palagonite.

1916 Geol. Mag. 3 387 The palagonitization process may work so completely in the glass that it finally breaks down.
1978 Nature 13 July 148/1 The behaviour of the REE [= rare earth elements] during palagonitisation of the glassy-rinds during the low-temperature weathering process is most marked by the variation in abundance between the margins and interiors of the 4.5 and 5.0 Myr basalts.
1993 Jrnl. Petrol. 34 718 Basaltic glass probably experienced hydration which may have involved palagonitization.
