The selected samples are mainly intermediary weathered leptynite and intercalated with chlorite schist.
The exposed strata in the Changfagou ore district are mainly lower members of the Archean Yangjiadian Group (Figure 2), which is an association of biotite-bearing plagioclase gneiss, amphibolite gneiss, leptynite, and amphibolite.

The garnetiferous biotite gneisses (khondalites) and the associated layered complex of garnetiferous quartzo-felspathic granulites (leptynites) and non-garnetiferous quartzo-felspathic granulites (alaskites) constitute an assemblage of metasediments injected by granitic materials, and recrystallised under deep-seated palingenetic conditions into a migmatite complex.
The Drosendorf terrane (Drosendorf nappe in Austria, Tollman 1982), largely identical with the previously used the Varied group, consists essentially of a thick supracrustal sequences of greywacke-pelitic lithology with locally frequent intercalations of marbles, calc-silicate gneisses, graphitic rocks, quartzites, leptynites and amphibolites.
