An albite-anorthite assemblage in low-grade amphibolite facies rocks
Poikiloblastic amphibole schists from an ophiolite series in the vicinity of the Tertiary Bergell granite contain the assemblage albite (An 0)-anorthite (An 95), actinolite-pargasite, together with clinozoisite. TEM illustrates how large andesine crystals with a periodic APB (anti-phase boundaries) structure of e plagioclase change over a few hundred angstroms to pure albite and pure PT anorthi...
متن کاملPeriodontal status among patients with diabetes in Nuuk, Greenland
BACKGROUND Diabetes is becoming more common in the Greenlandic population. Patients with diabetes are more prone to periodontal disease. Periodontal status may have an effect on metabolic control. OBJECTIVE The aim of this study was to estimate the prevalence of periodontitis amongst patients with diabetes in Nuuk, Greenland, and secondly, to observe if dental care was associated with improve...
متن کاملQuantifying supraglacial meltwater pathways in the Paakitsoq region, West Greenland
Increased summer ice velocities on the Greenland ice sheet are driven by meltwater input to the subglacial environment. However, spatial patterns of surface input and partitioning of meltwater between different pathways to the base remain poorly understood. To further our understanding of surface drainage, we apply a supraglacial hydrology model to the Paakitsoq region, West Greenland for three...
متن کاملTracking Yukon-Tanana Terrane VMS Host Stratigraphy and Intrusion-Related Gold in the Southern Sylvester Allochthon
This report describes a new mapping project in the Cassiar Mountains, located 70 kilometres northeast of Dease Lake in northern British Columbia. The area is attractive for two reasons. First, it contains rocks that are likely correlative with those of the Yukon-Tanana Terrane, a tract with known volcanogenic massive sulphide potential. Second, combined geological and regional geochemical data ...
متن کاملTriassic-jurassic Boundary on the Southern Margin of Tethys: Implications of Facies, Tectonics and Volcanism
The facies changes, tectonics and magmatism across the Triassic–Jurassic boundary in the southern Tethyan margin have been studied in Egypt, Sudan, Jordan and Saudi Arabia. In Saudi Arabia and Jordan an unconformable contact is recognized between the Upper Triassic and Lower Jurassic rocks. This unconformity surface is marked by the truncation of the fluvial clastics of the uppermost Triassic b...
