OUMNH number Name and quarry location Geological description
936stone 936 Alabastro antico, locality unknown Limestone breccia. Calcite travertine clasts, and a few gastropod shells, in a micritic (peloidal in places) matrix.
943stone 943 Breccia rossa, locality unknown Metamorphosed (tectonised) limestone breccia with calcite/hematite-filled fractures, solution seams and stylolites.
944stone 944 Breccia corallina, from Verzirhan, Bilecik,Turkey Weakly metamorphosed limestone breccia with stylolitised clast boundaries, and with small cavities filled with sparry calcite.
945stone 945 Breccia pavonazza bruna o dal suffragio, locality unknown Polymict breccia-conglomerate. Smaller clasts in matrix are realatively rounded and ferruginous reddish-brown, and all clasts are have ferruginous mainly stylolitic clast boundaries Voids are filled with sparry calcite. A few clasts contain bright green, 'fushsite' (chromium-bearing muscovite).
946stone 946 Breccia traccagnina, breccia Capitolina, locality unknown Polymict limestone conglomerate.
947stone 947 Breccia di Settebasi, from Isle of Skyros, Sporades, Central Greece Sheared limestone conglomerate, metamorphosed to marble.
948stone 948 Broccatellone, from Verzirhan, Bilecik,Turkey Tectonised limestone breccia-conglomerate.
949stone 949 Breccia Medicea or 'Africano', from Seravezza, Lucca, Tuscany, Italy Tectonised polymict breccia-conglomerate of limestone and marble clasts with solution-modified clast contacts.
950stone 950 Breccia corallina, from Verzirhan, Bilecik,Turkey Tectonic brecciated limestone breccia, heavily fractured with stylolites and solution-modified clast boundaries.
951stone 951 Breccia bigia, locality unknown Well-sorted polymict limestone conglomerate.
952stone 952 Breccia di Siena, from Siena, Tuscany, Italy Sheared polymict limestone conglomerate. The shearing may have been synsedimentary: Solution seams and stylolites are pervasive. Perhaps a sheared debris flow.
953stone 953 Breccia persichina, perhaps breccia Medicea, from Stazzema or Seravezza, Lucca, Tuscany, Italy Sheared, metamorphosed solution-modified limestone with stylolites, not entirely recrystallised to marble, fossils are still widely evident.
954stone 954 Fior di pesco Apuano from Stazzema, near Seravezza, Lucca, Tuscany, Italy Marble breccia; a sheared and tectonised limestone conglomerate.
955stone 955 Fior di pesco Apuano, from Stazzema, near Seravezza, Lucca, Tuscany, Italy Heavily fractured calcite marble breccia; a sheared and tectonised limestone conglomerate.
962stone 962 Verde antico, from Larissa, Thessaly, Greece Breccia with clasts mainly of serpentinite/ophicalcite, and a few of marble.
963stone 963 Serpentina di Santa Caterina, from Santa Caterina, island of Elba, Livorno, Tuscany, Italy Serpentinite, finely brecciated and veined with calcite.
968stone 968 almost certainly breccia del Taigeto, breccia verde di Sparta, from the area of Krokees (Levetsova), Laconia, Peloponnese, Greece Synsedimentary breccio-conglomerate with clasts of porphyritic andesite.
969stone 969 Breccia verde d'Egitto, breccia universale, from Wadi Hammamat, Eastern Desert, Egypt Metaconglomerate of metamorphic and igneous clasts (pink granite, banded tuff, serpentinite etc) in an epidotised matrix containing chlorite and abundant quartz grains. Cf no.679.
971stone 971 Pudingo di Toscana, from Tuscany, Italy Polymict breccio-conglomerate, clasts are largely quartz or chert, and some have inclusions of pyrite. Matrix is calcarenite.
975stone 975 most probably breccia Medici di Siena, from Siena, Tuscany, Italy Fine-grained calcite marble breccia; a sheared and metamorphosed limestone breccia.
976stone 976 'Diaspro d'Egitto', locality unknown Breccia of green iron-rich prase/aventurine? fragments in a chalcedony matrix. Abundant ferruginous ‘debris’ is in places altered to orange goethitic and red hematitic spherules. A broad colourless chalcedony vein traverses specimen.
977stone 977 Sicilian jasper, diaspro di Sicilia, from Sicily, Italy Brecciated orange-brown jasper with fractured agate matrix. Goethite forms inclusions in matrix and full/partial rims to clasts. Dendritic manganese oxides emanate from clast fractures, crystalline quartz fills smaller voids, microcrystalline calcite the larger ones.
978stone 978 Sicilian jasper, diaspro di Sicilia, from Sicily, Italy Brecciated red jasper with heavily fractured agate matrix patchily speckled with hematitic inclusions. Diffuse brown goethite forms inclusions and full/partial rims to clasts. Dendritic manganese oxides are common along fractures in matrix, crystalline quartz fills smaller voids, microcrystalline calcite the larger ones.
979stone 979 Diaspro delle Alpi, from the Alps Poorly sorted breccio-conglomerate with very heavily fractured argillaceous siliceous clasts and a calcarenite cement. Brown is filler/polishing compound.
982stone 982 Sicilian jasper, diaspro di Sicilia, from Sicily, Italy Brecciated yellow-brown jasper, agate-filled fractures and matrix, voids filled with crystalline quartz.
1000stone 1000 Granito delle Alpi, from the Alps; or perhaps from Elba, Livorno, Tuscany, Italy Breccia of calcite marble, limestone, serpentine, and metagabbro clasts, with a single large metagabbro clast forming the greater part of the specimen.
