1 Ankerite, haematite, mica and feldspar have also been identified in smaller quantities.

2 IV. carbonate mineral contain iron , include siderite, ankerite, etc.

3 Ankerite is one of the main gangue minerals genetically related to gold mineralization in the Baguamiao giant gold deposit.

4 Ankerite microclinite, a special type of rock, is closely related to the ore-forming process of massive sulfide deposits in the East Liaoning Proterozoic rift.

5 Fe-carbonates include early ankerite-dolomite, ankerite and later siderite with calcite and quartz.

6 X-ray studies show that carbonate minerals are aragonite, high-Mg calcite, and lesser dolomite, ankerite and siderite.

7 The major nonmetallic minerals are quartz, chansthealite, and miner ores are calcite, ankerite. illite hydromica and other clay minerals.

8 The authigenic minerals include secondary overgrowth quartz, kaolinite and illite before CO2 influx. After CO2 influx, the main cements include dawsonite and ankerite.
