Structure et caractérisation des matériaux utilisés
dans la construction d'une mosaïque romaine de la cité de
Volubilis (Maroc) La cité romaine de Volubilis est connue pour ses belles mosaïques. Une mosaïque romaine est formée de trois couches, qui sont, de la base vers le sommet : (i) une couche dite « hérisson », (ii) une couche de mortier grossier (rudus + nucléus) et (iii) une couche de motifs rocheux appelés « tesselles », fixés par un liant fin ou bain de pose, l'ensemble constituant le tesselatum. Le mortier grossier prélevé dans la mosaïque de Flavius Germanus est constitué de quartz et de calcite, avec du feldspath et, probablement, du mica et de la dolomie en faibles quantités. Le liant fin est formé de calcite et de quartz. Les tesselles calcaires (blanche, marron et rose) montrent un faciès pétrographique qui va du calcaire micritique au calcaire oolithique. En revanche, les tesselles noires et rouge brique ont été confectionnées respectivement à partir de marbre et de grès rouge. D'autres tesselles, de couleur rouge, ont été faites à base de terre cuite. Les autres couleurs, comme le jaune, le bleu, le vert et le gris, ont été obtenues par des pâtes de verre artificiel de compositions chimiques différentes. Pour citer cet article : A.

The Liuchiu Hsu island offshore SW Taiwan: tectonic versus diapiric
anticline development and comparisons with onshore structures A structural and microtectonic analysis performed in the Liuchiu Hsu island demonstrates that its Plio-Pleistocene tectonic evolution was dominated by alternating NW–SE shortening and local radial extension caused by mud diapirism. Previous models based on seismic data considering both the formation of the Liuchiu Hsu island and the fold development in SW Taiwan as mainly driven by mud diapirism, fail to account for both the asymmetry of the west vergent thrust-related anticlines onshore and the elongated character of the ridges formed by diapir alignments offshore, which rather argue in favour of a tectonic origin.

- Deformation mechanisms and fluid-driven mass transfers in the recent

Comptes rendus Geoscience
Deformation mechanisms and fluid-driven mass transfers in the recent
fault zones of the Corinth Rift (Greece) Normal fault zones affecting the pre-rift limestones in the Corinth Rift comprise breccia corridors separated by slip surfaces, but also numerous stylolites and calcite veins attesting the importance of fluid-driven mass transfer during a(inter)seismic episodes of fault activity. Cathodoluminescence microscopy shows that external (meteoric?) waters circulated in the fault zones, whereas mass transfer in the surrounding rocks implied a closed system with water chemically equilibrated with the host limestone. From these observations, we propose preliminary qualitative models of structural development and fluid flow in active normal fault zones in superficial conditions, with a tendency to concentration of deformation and fluid-flow-related to fault-tip propagation.

Comptes
rendus Geoscience 2004 - Volume 336 - Numéro 4-5 - pp: 281-290 Kinematics of the Corinth Gulf inferred from calcite dating and syntectonic
sedimentary characteristics New data on faults from the western-central area of the Corinth Gulf give new insights into the kinematics of this rift zone. The Xylokastro Fault was active 1 Myr ago and also around 108 ka. The Doumena Fault is younger than the Pirgaki Fault, so out-of-sequence, and was active 125 ka ago. Cements from two faults sampled on the northern coast have given two ages, respectively close to 300–400 ka and greater than 1 Myr. These new data confirm the recent fault activity on the two rift borders. To cite this article: C. Causse et al., C. R. Geoscience 336 (2004). Normal faulting / Greece / Corinth Rift / Th/U dating |

Avian eggshell mineralization: biochemical and functional characterization
of matrix proteins The eggshell of the hen is a highly ordered and mineralised structure, which is sequentially deposited within an acellular milieu - the uterine fluid secreted by the distal oviduct. Spherulitic crystal growth of calcite is initiated on organic aggregates on surface of the eggshell membranes, followed by competition between radial crystallites for space to form a compact columnar biomineral. The exceptional mechanical properties associated with the well-defined eggshell ultrastructure and texture arise from the control of crystal morphology and growth by the organic matrix, and, amongst them, proteins specific to the uterus and eggshell (ovocleidins and ovocalyxins). The changes in uterine fluid constituents with stages of egg calcification, their effects on morphology of calcite grown in vitro, and the relationship between eggshell texture and mechanical properties point to this control of eggshell fabric.

Late Roman cooking pottery from the Tavoliere area (Southern Italy):
raw materials and technological aspects This study describes the results of petrographical, mineralogical and chemical analyses carried out on coarse tempered cooking pottery, sampled in the archaeological sites of Herdonia, Posta Crusta (Ordona, FG) and San Giusto (Lucera, FG). From the latter site, two fragments of a pottery kiln, coeval with sherds (IV and V centuries AD), were also investigated. Two groups of clayey sediments of different nature (alluvial and marine) sampled in the neighbouring of the archaeological sites were also analysed. By means of the petrographical analyses, all cooking pottery and the two kiln fragments were grouped in the same coarse tempered group, characterised by the scarce presence of trachytic and glassy fragments, anhedral and zoned augitic pyroxenes and feldspars. PXRD analyses show an abundant presence of quartz and feldspars, followed by pyroxenes and variable quantities of calcite and hematite. Among clay minerals, illite plus muscovite are more abundant than smectite. XRF analyses data display SiO2, Al2O3, Fe2O3 and K2O as main oxides, with variable quantities of CaO. In the case of the clayey samples, petrographical investigations on thin-section of psammitic fractions outlined the differences between Argille subappennine (Marine group—Pleistocene) and the alluvial deposits of Celone River (Alluvial group—Holocene). The occurrence of volcanic products, chert, garnet, quartzarenites and limestones in the archaeological materials and in the alluvial samples, let us suppose that cooking pottery was made with alluvial clayey silt. The apparent chemical discordance between pottery and alluvial samples bulk compositions can be due to textural and compositional variability of the alluvial deposits. All ceramics were fired in oxidising conditions, although in many cases a “dark core” was still present. Textural features, observed through petrographical microscope, and PXRD analyses suggested a firing temperature between 600 and 800 °C.
