The ferriferous varieties are liable to a particular kind of alteration, known as "schillerization," which results in the separation of the iron as very fine films of oxide and hydroxides along the cleavage cracks of the mineral.
Here, in addition to schillerization, the original enstatite has been altered by hydration and the product has approximately the composition of serpentine.
