Biosparites are limestones consisting of calcareous fragments in a matrix of recrystallised calcite (sparite). 

Cementation is the binding together of the components of a rock by interstitial crystals. Sparite is the most eommon cement in limestones. 

Sparite is clearly crystalline, interstitial calcite in carbonate rocks, which acts as a cement binding larger particles. 

The bedrock at the quarry is composed of black blue-colored sparitic limestone and dark grey-colored sandstone. They are the part of Istanbul Paleozoic Units and the age of these rocks is about Early Devonian (Abdiisselamoglu, 1977 Onalan, 1981). 

Kl Southeastern part Massive, compose of calcite mineral and corals. Sparitic limestone...
