Standard Test Method for Rapid Determination of Carbonate Content of SoilsMore info
1.1 This test method covers the determination of carbonate content of soils and soft rock which can be readily broken down by mechanical effort. It is a gasometric method that uses a simple portable apparatus. Results should be clearly stated as the calcite equivalent in percent because different carbonate species cover a wide range of percent calcite equivalent as shown below for a number of carbonates:
Species | Cation | Calcite |
Magnesite | Mg | 117.0 |
Dolomite | Ca, Mg | 108.6 |
Calcite | Ca | 100.0 |
Aragonite | Ca | 100.0 |
Rhodocrosite | Mn | 87.1 |
Siderite | Fe | 86.4 |
Smithsonite | Zn | 79.8 |
Witherite | Ba | 50.7 |
Cerrusite | Pb | 37.5 |
