Examples of haematite

• This study concentrates on the latter which contain abundant chlorite-rich layers, commonly rich in magnetite and haematite grains.

• The red colour of the dolomite is due to abundant haematite crystallites that grew in the dolomite crystal fabric.

• Thus, dolomite vein formation and haematite precipitation were two distinct events, which likely record different conditions.

• Rather, haematite precipitation postdated the dolomite and took advantage of the dolomite crystal fabric.

• The nodules are dispersed throughout a clay and haematite-rich matrix.

• In addition, haematite is commonly present, to locally abundant.

• The calcination of haematite from a lower to a higher temperature could be used to monitor the water content in the lattice.

• These observations indicate that the dolomite and haematite were not precipitated as two coeval minerals.
