Magnetic pseudomorph?

This looks the result of a metasomatic process in contact metamorphism whereby iron and calcium are provided by the sedimentary rocks transforming the quartz and feldspar of igneous intrusive front to form epidote and magnetite. White matrix could be feldspar remnants; the rest of metasomatic skarn process should be mica group minerals easily weathered facilitating the collection of the epidote.


Graphic demonstration of the magnetic properties:


Epidote - clinozoisite, diopside and magnetite from unknown locality also in Pakistan (received without label as a gift from a Pakistani dealer). This is an alpine type growth, completely different to metasomatic transformation origin of related magnetic pseudo-octahedral Raskoh epidote.
