GEOLOGY, HYDROTHERMAL ALTERATION AND MINERALIZATION OF THE GOLD EAGLE DEPOSIT: A NEW DISCOVERY IN THE RED LAKE CAMP, CANADA
(2012-04-02)
Greenstone belts have been recognized as highly prospective settings for high grade gold mineralization, and are host to a number of world class quartz-carbonate vein deposits, which account for approximately 13% of the ...
From cessation of south-directed mid-crust extrusion to onset of orogen-parallel extension, NW Nepal Himalaya
(2012-09-25)
Field mapping and, structural, microstructural, and chronological analyses confirm the existence of a segment of the Gurla-Mandhata-Humla fault, an orogen-parallel strike-slip dominated shear zone in the upper Karnali ...
Application of simulated lung fluid analysis to characterize the influence of smelter activity on the respiratory bioaccessibility of nickel-bearing soils in Kalgoorlie, Western Australia
(2008-07-08)
The city of Kalgoorlie in Western Australia has been labeled an “asthma hot spot” attributed to mining activity, prompting further investigation into toxic elements (Lee et al., 2006). Inhalation of nickel-bearing particles ...
Paleoecology, Diagenesis and Biological Affinity of Tetradiids in the Upper Ordovician (Sandbian) Black River Group of the Kingston Area, Ontario, Canada
(2016-06-14)
Tetradiids are a group of colonial, tubular fossils that occur globally in Middle to Upper Ordovician strata. Tetradiids were first described as a type of tabulate coral; however, based on their four-fold symmetry, division, ...
Numerical tools for interpreting rock surface roughness
(2015-06-01)
Visual recognition of the irregular shapes of natural objects and surfaces is crucial to the study of geology. Field geologists are aided by a learned ability to, at a glance, differentiate cohesive outcropping rock from ...
Hydrated Sodium-Magnesium Sulfate Minerals Associated with Inland Saline Systems
(2010-09-16)
Hydrated sodium-magnesium sulfate minerals are common in many continental evaporite settings around the world. The crystallization sequence of these minerals depends on such parameters as the composition of the parent ...
Characterization of Carlin-Type Auriferous Arsenian Pyrite from the Goldstrike Property using EMP, SIMS, and VESPERS Synchrotron u-XRF: Constraints to Ore Deposition Mechanisms
(2012-09-08)
The Goldstrike property, located in northern Nevada within the Carlin Trend, contains one of the largest Carlin-type Au deposits in the world. The vast majority of this mineralization, formed in the Eocene, is in the form ...
The measurement of the Se/S ratios in sulphide minerals and their application to ore deposit studies
(2008-02-25)
New analytical techniques have been developed for the determination of selenium concentrations in sulphide minerals to assess the utility of the Se/S concentration ratios in tracing fluids associated with ore deposit ...
Origin of Visean (Mississippian) Frobisher Group Coated Grainstone Shoals in the Williston Basin: Deposition and Diagenesis
The Frobisher Beds of southeastern Saskatchewan are part of an extensive conventional oil and gas play hosted in grainy carbonate rocks, long interpreted as marine oolites. This sedimentological and diagenetic study of ...
Provenance of Holocene Calcareous Aeolianites, Eastern South Australia
(2016-10-14)
The southeastern coast of South Australia contains a spectacular and world-renown suite of Quaternary calcareous aeolianites. This study is focused on the provenance of components in the Holocene sector of this carbonate ...
