Experimental Compaction of Carbonate Sediments
Recent carbonate sediments of different grain size and with different carbonate content were compacted under pressures of up to 650 atm. The reduction of porosity with increasing pressure as well as the progress of compaction with time at constant pressure and their dependance on grain size, temperature and chemical nature of the pore medium were evaluated and presented graphically. Of special importance for a comparison with natural processes is the differentiated investigation of the various interdependent mechanisms which produce compaction: reorientation of the individual grains, plastic and shear deformation of the components and chemical processes such as pressure solution and solution transport.
