Announcing the launch of SkyFix XP, Senior-Vice President of the Thales Positioning Based Solutions Group, Stanislas Guerin said: "SkyFix XP is ideal for all offshore operations and activities, providing highly reliable and dynamic decimetric
positioning accuracy anywhere in the world, with no range limitations from stations.
More locally, some decimetric
to metric shear zones with ankerite-chlorite alteration and quartz-carbonate veins are developed within the volcaniclastic sequence.
It consists of sandstones, dark quartzites and black slates alternating on a decimetric
to metric scale.
Interpretation: The shales and sandstones are arranged in decimetric
Bouma-type sequences, Tc-e and Tb-e.
Characteristically, different (up to 5) decimetric
beds of conglomerate are recognised within the argillite units.
Beds are tens to hundreds metres long and decimetric
to metric in thickness (Arche and Lopez-Gomez 2005; De la Horra et al.
The oldest recognized rocks form a heterogeneous sequence of alternating decimetric
to metric thick layers of brown shales, quartzites and greywackes.
Thus, each elemental sequenceisconsidered equivalent in terms of temporal meaning and tendency to other well-known cycles, such as metric to decimetric
cycles made up of marls, charophyte limestones and palustrine limestones representing infilling and reduction of the depth of small lakes and ponds.
At the base, in the Rabejac Fm, both reptilians (Pelycosauria, Parareptilia, Lepidosauria), and amphibians (Temnospondyls) show a moderate size ranging from decimetric
to metric; the latters being less abundant and diversified.
At the base of a decimetric
light grey limestone bed, 32 m above the base of the unit, a maze of burrows attributed to Spongeliomorpha sudolica together with Asterosoma ludwigae (Fig.
The upper calcareous member is formed by yellow limestones with some detrital micas, arranged in decimetric
12), is a thick alternation of anhydrite and dolomite in metric to decimetric
