Energy, Waste and the Environment: A Geochemical Perspective
Rather, ankerite tends to occur in the form of patchy films lining the surfaces of
the many cleats (i.e., micro-joints) that cut the coal itself (Fig. 2b). Cleat is
considered to develop relatively late in the post-burial history of coal-forming
peats ...

Carbonate minerals other than calcite such as ankerite Ca(Mg, Fe)(CO3)2 and
breunnerite (Mg, Fe)CO3 can be useful identifiers. The most important type of
wall-rock alteration in gold, base metal and uranium deposits is characterized by
the ...

Rare Earth Minerals: Chemistry, Origin and Ore Deposits
All of the carbonate specimens are ankerite, with the exception of one siderite
which was found to coexist with ankerite in sample TZ-93. The carbonate r>13C
values have a restricted range, from —2.1 to -5.9% (relative to the PDB standard).

Second Report on a Cooperative Investigation of the ...
ANKEKITE Ca(Fe,Mg)(CO,), [See alto Carbonate minerals (mixed) ] Ankerite is
distinguished from dolomite in that it contains more iron than magnesium. It
occurs as a gangue mineral in many ore deposits, particularly those in limestone
and ...
Fe203. Peak temperature differences enable one to distinguish ankerite from
mixtures of siderite, magnesite and calcite (the presence of a superimposed peak
ofcalcite may be detected as described under dolomite) (Fig.20, curves 1, 2 and 3
).

U.S. Geological Survey Bulletin
The evolution of dolomitic cements is similar to the evolution of ferroan calcite
cements; iron-rich dolomite or ankerite replaced or succeeded earlier iron-free or
iron-poor dolomite. This order of genesis is best displayed by stained thin
sections ...
