variegated marl Explanation: see GDT "Roche sédimentaire généralement friable constituée d'un mélange de calcaire et d'argile (pour 35 à 65 %), formant la transition entre les calcaires argileux (= calcaires marneux, avec 5 à 35 % d'argile) et les argiles calcareuses (= marnes argileuses, avec 65 à 95 % d'argile). Dépôt terreux, tendre et non consolidé, formé de carbonate de calcium ou de carbonate de magnésium, ou d'un mélange des deux, et souvent de coquillages, généralement mêlés à des quantités variables d'argile ou d'autres impuretés." "Variegated marls, Between the third and fourth there is, in Germany, another group, called the Muschelkalk, a word expressing a limestone full of shells ... The variegated marl beds which constitute the uppermost group of the formation, present two additional genera of huge saurians,- the phytosaurus and mastodonsaurus." http://www.esp.org/books/chambers/vestiges/facsimile/content... "Section VII. Red Sandstone Group (Red or Variegated Marl, Muschelkalk, Red or Variegated Sandstone, Zechsttiii and liothliegeades) 353 " http://www.archive.org/stream/ageologicalmanu01bechgoog/ageo... "together with soft, red or variegated marl, sandstone, conglomerate, and greenstone." http://www.mta.gov.tr/v2.0/eng/dergi_pdf/66/3.pdf |

colored marls Explanation: colored marls NAGRA regional geological investigation programme in Northern Switzerland, with the aim of exploring the underground geological structure of Switzerland in general and the crystalline basement beneath the Mesozoic sedimentary cover in particular. Le Quaternaire traversé montre une alternance horizontale et verticale dargiles, de silts, de sables, de graviers et de craies lacustres. Le sommet de la séquence est défini par la couverture dhumus, et la base par la roche en place. Le Tertiaire sous-jacent est constitué de Molasse deau douce inférieure sur une épaisseur de 124 m, comprenant des marnes bariolées, des sables et grès peu cimentés, ainsi que de Sidérolithique sur une épaisseur de 7 m (en général des argiles de couleur ocre contenant des nodules de minerai de fer). Le Malm est constitué dune séquence de 252 m de puissance de calcaires avec des intercalations marneuses de faible épaisseur. The Quaternary consists of a vertical and horizontal alternation of clay, silt, sand, gravel and lacustrine chalk. The upper boundary of the sequence is the overlying humus and the lower boundary the start of the consolidated rock. The Tertiary underlying the Quaternary is composed of a 124 m thick layer of Lower Freshwater Molasse (coloured marls and poorly cemented sands and sandstones) and a 7 m thick bean iron ore formation (mostly ochre-coloured clays with inclusions of bean ore). The Malm, which is approximately 252 m thick, comprises a sequence of limestones with thin marl intercalations. http://www.google.co.in/url?sa=t&source=web&cd=1&ved=0CBYQFj... |
