in the centeral iranian volcanic belt (civb), north-west of shahre-babak, in area of javazm, dehaj and khabr, about 20 plutonic porphyritic tonalitic to granodioritic masses (1-50 km2) are intruded into a varity of rock sequences from eocene to early miocene in age. tonalitic and granodioritic rocks are some part of dehaj-sardoieh belt and having early miocene age. the civb contains intrusive a...

All sorts of anomaly graphs of physical geography and geochemistry, such as aeromagnetic anomaly graphs, bouguer gravity anomaly graphs, regional geochemical anomaly graphs and so on, are all parameters for exploration deposit. And following the remote sensing image shortwave and infrared bands coming, researchers of remote sense have engaged in many highly effective experiments and have approv...

introduction several valuable calcite deposits are located in ghare-gheshlagh, south basin of urmia lake, nw iran. ghare-gheshlagh area is situated in the northern part of tectono-sedimentary unit, forming nw part of tertiary sanandaj-sirjan geological belt (stocklin and nabavi, 1972). the predominant rock types of the area include light color limestones (qom formation) and quaternary alluviums...

Concentrations of the incompatible trace elements and REEs in the upper mantle rocks of the Northern Semail ophiolite are very low, as typical in the residua of partial melting and in the early products of a fractionating magma. However, their geochemical characteristics have shown indications of hydrous magmas that more likely related to a subduction environment. Melt extraction can play a cru...

BACKGROUND Herlyn-Werner-Wunderlich syndrome is a rare congenital urogenital anomaly characterised by uterus didelphys with blind hemivagina and ipsilateral renal agenesis. Children usually have progressive pelvic pain after menarche, palpable mass due to hemihaemato(metro)colpos or pelvic inflammatory disease. The diagnosis usually requires a suspicion of this rare genitourinary syndrome. CA...

Local structural property of an image is often considered in image enhancement with various high/low pass filters. Spatial association indexes (autocorrelation, covariance, and variogram) have been commonly used to characterize the local structure of surfaces for data interpolation in kriging. Singularity is another index measuring the scaling invariant property of measures from a multifractal ...

The dynamics of mantle flow and melting of a ridge-centered plume were investigated with three-dimensional variable-viscosity numerical models, focusing on three buoyancy sources: temperature, melt depletion, and melt retention. The width, W, to which a plume spreads along a ridge axis, depends on plume volume flux, Q, full spreading rate, U, buoyancy number, B, and ambientrplume viscosity cont...

A masquerader is an (often external) attacker who, after succeeding in obtaining a legitimate user’s credentials, attempts to use the stolen identity to carry out malicious actions. Automatic detection of masquerading attacks is generally undertaken by approaching the problem from an anomaly detection perspective: a model of normal behaviour for each user is constructed and significant departur...

Petrology and geochemical characteristics of granitic rocks from South Sulawesi, especially from Polewaliand Masamba area are presented in order to elucidate their origin of magma and geodynamic setting. The granitic rocks in these areas are dominated by granodiorite and granite in composition. Quartz, K-feldspar and plagioclase occur as major phases with hornblende and biotite as major ferroma...
