Rb–Sr and U–Pb isotopic data for granulite facies rocks, forming textural relics with respect to eclogite facies metamorphism in the Western Gneiss Region (WGR) of Norway, highlight the importance of textures and mineral reaction kinetics for the interpretation of geochronological data. Studied rocks from Bårdsholmen, southern WGR, were subjected to granulite facies metamorphism at 955 ± 3 Ma (...
More than 200 specimens from different occurrences of the Rogaland igneous complex and surrounding granulite facies metamorphic rocks (S. W. Norway) have been analysed by a direct non-destructive proton induced gamma-ray emission (PIGE) technique. The fluorine contents vary from < 25 ppm to 3500 ppm. There is a good correlation between the concentration of fluorine and that of phosphorus for ig...
Anti-epileptic drugs administered during pregnancy can cause structural defects in the growing fetus and result in adverse neurodevelopmental outcome later in life. Fetal valproate syndrome (FVS) results from teratogenic effects of valproic acid exposure in the prenatal period. It is characterised by a distinctive dysmorphic facies and a cluster of minor and major anomalies, as well as developm...
Freeman-Sheldon syndrome is a morphologically well-defined syndrome that results in a dysmorphic status combining bone anomalies and joint contractures with characteristic facies. FSS (FreemanSheldon Syndrome) is also known as craniocarpotarsal dysplasia (or dystrophy), distal arthrogryposis type IIA (DAIIA), whistling face syndrome, and whistling face-windmill vane hand syndrome. The syndrome ...
This study aims to identify favorable oil–gas reservoir facies in the Chishan group of the Wubao fault zone (Gaoyou sag, Subei basin, China) using the methods of outcrops and cores observation, granularity analysis, scanning electron microscope, log data, etc. The results suggest that the Chishan group in the studied area mainly develops desert sedimentary system, and contains five kinds of fac...
The Arghavan Valley of Binalood county located at Khorasan Razavi province, is a habitat for valuable and almost rare plant community in eastern Iran which dominated by Cercis griffithii Boiss. shrubs. This habitat is very important for environmental aspects and combat desertification. It’s documented where arid and semi-arid shrublands destroyed, it is very difficult to restore. The Arghavan v...
During the 2006–2007 austral season, the ANDRILL McMurdo Ice Shelf Project recovered a core 1285 m-long (AND-1B) from Windless Bight in the McMurdo Sound region. This core contains a range of lithologies, including both siliciclastic and volcanic diamictites, sandstones and mudstones; diatomites; and volcanic ash/tuff and one phonolitic lava fl ow. The succession has been subdivided into eight ...
This article presents Q-Facies, an open-source Python package for quantitative analysis of hydrochemical facies (HF). HF is widely used to interpret the chemical characteristics groundwater. However, it difficult analyse its spatial or temporal variability due qualitative nature and small number classes. To avoid these limitations, Q-Facies performs parametrization based on calculation five sta...
The metabasite rocks from north of Shahrekord, which is a part of structural zone of Sanandaj-Sirjan, are undergone medium temperature – high pressure metamorphism (eclogite facies). These rocks then were subjected to a retrograde metamorphism (amphibolite facies). A distinct compositional zoning is preserved in fresh garnets which are formed during eclogite facies. The compositional or growth ...
