Name and quarry location: | Breccia corallina, from Verzirhan, Bilecik,Turkey |
Geological description: | Limestone breccia with extensive solution-modified stylolitic clast contacts, and calcite-filled fractures/veins. |
Comments: | This is very typical breccia corallina, quarried near the village of Vezirhan in Bilecik, Turkey close to a tributary of the River Sakarya. In Roman times the area was Bythinia and the river was called Sagarius, hance its old name marmor Sagarium. The colour of the matrix can vary from orange to salmon pink or brown. Nos. 910, 944, 950 are all thought also to be examples of breccia corallina, the less sheared samples showing the same stylolitic clast contacts. Limestone breccia is still quarried in the area under the trade name rosalia, but it is beige coloured with only slender veins of orange. |
