Diagenetic replacement phenomena involving dolomite, silica, and calcite are demonstrated from oolitic horizons in the Cambro-Ordovician 'Durness' carbonates of northwest Scotland. The oolite texture of the rocks has exerted a control over the patterns of diagenesis and facilitates the interpretation of the diagenetic history. A possible five-stage diagenetic sequence is proposed to account for the observed relationships of the recrystallization and authigenic phenomena. A dilemma regarding a void filling interpretation of drusy calcite textures is demonstrated and arguments favoring the use of the term 'calcitization' rather than 'dedolomitization' are offered.
