Name and quarry location: | Breccia di Siena, from Siena, Tuscany, Italy |
Geological description: | Sheared polymict limestone conglomerate. The shearing may have been synsedimentary: Solution seams and stylolites are pervasive. Perhaps a sheared debris flow. |
Comments: | This is the brown breccia that used to be obtained from Siena. There is a little yellow in some clasts but not as much as in no.480, another example of this stone. |
