Precipitation-induced runoff from historical mine-waste located adjacent to the headwaters of the Snake River, Deer Creek, Saints John Creek, Grizzly Gulch, Stevens Gulch, and Leavenworth Creek contributes to the degradation of water quality in these streams. Because historical mine-waste piles have had long-term exposure to the atmosphere, it is surmised that runoff from these piles, induced b...

kajal kaolin deposit is located ~20 km northwest of hashtjin, ardebil province. field evidence and laboratory investigations show that the deposit is an alteration product of ignimbrites, tuffs, and trachy-andesites of eocene age. according to mineralogical data, the major rock-forming minerals include kaolinite, montmorillonite, polygorskite, orthoclase, zeolite (stilbite), quartz, and chalced...

Abstract This communication reports novel geochemical and geochronological data of granite from the southeastern part Bastar Craton, Central India. The studied samples are leucocratic in appearance composed quartz, K-feldspar, plagioclase feldspar, biotite decreasing order abundances. Apatite, sphene, zircon occur as accessory minerals. SiO2 Al2O3 content sample varies between 61 69 wt.% 13 15 ...

This study presents the first high-resolution speleothem-based hydrological reconstruction for much of last 2.7 kyr in central-western Mediterranean. The paleohydrological information comes from a combination five U-Th dated stalagmites two Mallorca island caves. Interpretations are based on records ?18O, ?13C and trace element analyses combined with mineralogical X-ray diffraction, fabrics mor...

-This paper presents the design and development of a Geochemical Expert System prototype (GES) for analyzing solution-mineral interactions in nature. The emphasis is placed on expert system design and knowledge representation. One of the most challenging and research-intensive steps was the identification of the key geochemical characteristics that would enable the expert system to identify sal...

the area is located 20 km northwest of kashmar and about 4 km of kalateh taimour in khorasan razavi province. the study area is part of tertiary volcanic-plutonic belt north of daruneh fault and its situation in tectonic inliers between two important active faults, doruneh and taknar. volcanic rocks are mainly intermediate to acid pyroclastic type. they formed during early tertiary. the volcani...

The key hypothesis to anomaly detection assumes anomalous behaviors are suspicious from a normality point of view. This work provides a new perspective, network service, to model network activity for detecting anomalies. Past models often suffer from lacking of model normality verification, only including particular behavior aspect, and focusing on individual model. To confront them, we propose...

Upon their initial discovery, hydrothermal vents and methane seeps were considered to be related but distinct ecosystems, with different distributions, geomorphology, temperatures, geochemical properties and mostly different species. However, subsequently discovered vents and seep systems have blurred this distinction. Here, we report on a composite, hydrothermal seep ecosystem at a subducting ...

Changes of variables giving the dual model are constructed explicitly for σ-models without isotropy. In particular, the jacobian is calculated to give the known results. The global aspects of the abelian case as well as some of those of the cases where the isometry group is simply connected are considered. Considering the anomalous case, we infer by a consistency argument that the ‘multiplicati...
