What is Dolomitic Limestone? (with pictures)

Dolomitic limestone is a type of rock that includes up to 50% dolomite. Normal limestone is primarily made up of calcite and aragonite, but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions — this process is called dolomitization. This type of rock was once referred to as magnesian limestone ...

Is it Calcite or Dolomite?

Calcite responds vigorously to acid, while dolomite responds less vigorously. Calcite is 3 on the Mohs Scale of Hardness, but dolomite is Mohs 4-4.5. One other difference you may see is the smoothness of the crystal faces on your specimen. Dolomite crystals, because of an unusual internal structure, may have slightly curved crystal faces, while ...

POROSITY LOGGING

1999-2-9 · limestone-equivalent porosity is a good choice for both neutron and density logs, because calcite has properties that are intermediate between dolomite and quartz. By averaging the apparent neutron and density porosities of a zone, effects of dolomite and quartz tend to cancel out. The true porosity may be 8
