Limestone Types, Properties, Composition,

Some limestones form from the cementation of sand and / or mud by way of calcite ( clastic limestone), and these often have the appearance of sandstone or mudstone.

QUANTITATIVE DETERMINATION OF CALCITE AND

Calcite and dolomite were differentiated quantitatively from calcite‐dolomite mixtures and limestones by a method based on the quantitative dissolution of calcite in pH 5.85N citrate buffer. The acidity and chelating ability of citrate favoured greatly the dissolution of calcite to that of dolomite. The method consisted of determination of
