The Great Serpentinite Belt of eastern Australia is a ∼1500 km long dismembered ophiolite assumed to be Cambrian based on studies small (typically <50 m2) exotic meta-igneous inclusions despite contrasting ages (Cambrian—Devonian) and complex P-T histories. To overcome these issues, we studied ∼18 km2 coherent block that provides robust geological context sampling the ophiolite. Zircon U-Pb-Hf-...

New geochemical data were presented for the mafic (basalts and gabbros) ultramafic (dunites, serpentinites pyroxenites) rocks from Mawat ophiolite exposed in Zagros suture zone northeastern Iraq. The mantle section of is composed serpentinized peridotites, harzburgites, dunites, chromitites pyroxenite dykes. crustal layered amphibole-rich gabbros, pegmatitic gabbros as well basalts minor felsic...

Abstract. Both ice sheets in Greenland and Antarctica are discharging into the ocean. In many regions along coast of sheets, icebergs calve a bay. If addition through calving is faster than their transport out embayment, will be frozen mélange with surrounding sea winter. this case, buttressing effect can considerably stronger any by mere would be. This turn stabilizes glacier terminus leads to...

The rotated-sigmoid form is a characteristic of old-growth, uneven-aged forest stands caused by past disturbances such as cutting, fire, disease, and insect attacks. The diameter frequency distribution of the rotated-sigmoid form is bimodal with the second rounded peak in the midsized classes, rather than a smooth, steeply descending, monotonic curve. In this study a finite mixture of two Weibu...

In recent years gene expression studies have increasingly made use of next generation sequencing technology. In turn, research concerning the appropriate statistical methods for the analysis of digital gene expression has flourished, primarily in the context of normalization and differential analysis. In this work, we focus on the question of clustering digital gene expression profiles as a mea...

the serpentinization of the harzburgitic mantle section of the bou azzer neoproterozoic ophiolite is studied by field mapping, structural observations, optical micrography, sem and x-ray diffractometry, and relationships with co, ni, cr and sulphides minerals are discussed. serpentinization occurred in two major steps with, i) intra-oceanic pseudomorphic serpentinization materialized by the iso...
