Processes

 

The processes affecting the carbonates in the soil can provoke two opposing effects: accumulation or destruction

 

1. Calcite formation

It may be useful to distinguish two categories of processes responsible for the accumulation of carbonates in soils:

Primary processes. Responsible for the initial accumulation of carbonates. Three very distinct processes can be distinguished:

Crystallization

Weathering

Bioformation

Secondary processes. Affecting earlier formed pedogenic carbonates, or conditioned by their presence. Three types of processes can be distinguished:

Recyistallization

Replacement

Displacement

 

2. Calcite destruction

Dissolution
