The first transition corresponds to goethite while the second (340[degrees]C) could be TC of iron sulphides, such as pyrrhotite, or transition from goethite to hematite.

The experiments showed that the amounts of hematite, Goethite in the samples are extremely low, so the increase can be observed for short-chain kaolinite.
They estimate their Utah site contains 3 million-plus tons of iron oxide hydroxide in the form of limonite, goethite and hematite, grading 95 percent on average.
Taylor and Schwertmann 1974; Barron and Torrent 2002), pedogenic maghemitc is generally thought to form by thermal dehydroxylation of goethite during intense bushfires (Anand and Gilkes 1987).
The mineralisation occurs as massive hematite and goethite enrichment within the BIF and is most likely the result of a mixture of hypogene and supergene enrichment.
They suggested that the presence of arsenate possibly decreased the net surface positive charge, which favoured the sorption of Zn on goethite surface.
