Abstract: 

Carbonate sediments undergo gravitational loading or tectonic stress in burial environments (Wanless, 1979). The response of uncemented carbonate sediments to overburden is mechanical and/or chemical (intergranular pressure dissolution) compactions. The resulting limestones mainly acquire diagenetic structures as nodular, flaser, etc. In some cases the formation of secondary (burial) dolomite in limestones is related to pressure dissolution processes. Three different styles of pressure dissolution are distinguished: (1) fitted fabric; (2) dissolution seams and (3) stylolites (Clary and Martire, 1996).
   Two examples of Jurassic and Lower Cretaceous limestones of Western Bulgaria with different pressure dissolution fabrics are discussed in the present study: Callovian limestones of Gorni Lozen section and Upper Jurassic-Lower Cretaceous limestones (Glozhene Fm.) of Komshtitsa, Barlya and Gorno Belotintsi sections.
