This report presents some strategies to predict metal mobility at mining sites. These strategies are based on chemical, physical, and geochemical information about metals and their interactions with the environment. An overview of conceptual models, metal sources, and relative mobility of metals under different geochemical conditions is presented, followed by a discussion of some important phys...

An extensive survey was conducted in this study to determine the spatial distribution and possible sources of 7 heavy metals (Pb, Cu, Zn, Cr, Ni, Co, Mn) in the soils in Perlis and producing a heavy metal distribution maps. 18 soil samples around Perlis undergo microwave digestion and analyzed by inductively coupled plasma mass spectrometry ICP-MS. The spatial distribution pattern shows that Cu...

Lithium isotopes have many advantageous characteristics as geochemical tracers for a wide range of geological processes, covering fluid/melt-mineral interactions from the Earth’s surface to the mantle. The latest developments in Li isotope geochemistry, in terms of measuring techniques, major geochemical reservoirs, the contrasting behaviors during near-surface weathering, and crust/ mantle cyc...

The rare earth elements (REE) are composed of the Lanthanide Series of 15 elements with atomic numbers (57) through (71) and yttrium (39). Because of their geochemical behavior, REE rarely form their own minerals and more commonly are found incorporated within the structure of other minerals. There is growing concern over the economical availability of REE because of their diverse and expanding...

lag is a general term applied to coarse grained (> 2 mm), hard, but partially weathered rockfragments, which are concentrated at the surface through attrition of finer materials. based on morphology,mineralogy and the origin of lag from the cobar region of australia, lag may be conveniently grouped intothree broad morpho-mineralogical categories; (a) those with a rough, blocky, lithic morpholog...

introduction mohammad-abad oryan is the only potential source of borate in the north-east of iran located in 50 km south of sabzevar. the area is located in tuff marl, tuffaceous marl, volcanic braccia and tuff braccia structures. remote sensing techniques, geological studies and integration of this data in gis were applied in an area of about 600 square kilometers to locate the promising areas...
