Disilicates and Ring Silicates
As the amount of leaching increases, metamict allanite may change from
greenish-brown to orange-brown in colour, and in highly metamict minerals the
redistribution of the constituents may result in grain heterogeneity due to the
complete ...

This indicated that neither uranium, thorium, nor lead had been selectively
leached, but rather there had been solution of either metamict zones of zircon or
thorite from the crystals. Inasmuch as the crystals were heavily stained before
acid ...
