Calcite and Dolomite University of Pittsburgh

Calcite and dolomite are very similar minerals. Both have the same hardness (H = 3), the same rhombohedral cleavage, and are found in identical geologic settings. The best way to tell one from the other is the acid test: a drop of 1 M HCl on calcite produces an instant, obvious fizz; a drop on dolomite

Marble University of Pittsburgh

With higher degrees of metamorphism, the large intergrown calcite and dolomite crystals are more obvious. Such samples are typically passed around in labs. This is a typical banded marble used as building stone. The banding comes from impurities in the original limestone (such as clay minerals) and is NOT due to any alignment of the calcite

Lactic acid, a chelating agent (GLDA), and in-situ gelled HCl-formic acids were investigated in this study. In some cases, rheology measurements and core flood experiments were conducted. The data were combined with the reaction study to

Relative weathering intensity of calcite versus dolomite

Department of Geological Sciences, University of Michigan, Ann Arbor, Michigan 48109, USA [1] Calcite and dolomite solubilities in open weathering environments are proportional to pCO 2 and inversely proportional to temperature, and dolomite solubility is progressively greater than calcite below 25 C.

Dolomite II and III contain a relative abundance of iron, whereas dolomite I has significantly lesser amounts. None of the dolomites have significant amounts of manganese or strontium. Elemental counts for late-stage calcite are variable with respect to iron and manganese and could explain the multiple zones seen in the late-stage calcite.

2 δ13C carb values measured in the Conasauga Group ~200 miles south, on the other side of the Rome Trough[6]. We interpret the positive δ13C carb trend in our data set as the result of a global trend of increased organic carbon burial and preservation.
