The Johanson Lake project is a two-year bedrock mapping program initiated by the Geological Survey and Development Branch in 2003 as part of the Toodoggone Targeted Geoscience Initiative (TGI). The project is focused on a belt of Mesozoic arc volcanic and plutonic rocks of the Quesnel Terrane in the eastern part of the McConnell Creek (94D) map sheet. This area contains a number of MINFILE occu...

The Los Menucos District, Rio Negro, Argentina, provides an excellent case history of a complex epithermal gold system mapped and explored using a combination of field mapping and multispectral/hyperspectral remote sensing. The district offers a host of argillic and advanced argillic alteration minerals at the surface, many of which are difficult to identify visually. A strategy utilizing regio...

Background and Aim: Brain mapping is a study of the anatomy and function of the CNS (central nervous system). Brain mapping has many techniques and these techniques are permanently changing and updating. From the beginning, brain mapping was invasive and for brain mapping, electrical stimulation of the exposed brain was needed. However, nowadays brain mapping does not require electrical stimula...

In the last ten years, the use of gamma-ray spectrometry for geological mapping and mineral exploration has shown considerable growth. With this growth, standardized procedures have been developed for the calibration and processing of the airborne measurements so that they will be independent of survey parameters. This paper describes some of the new developments to convert airborne data to gro...

Abstract This article presents a literature review of studies utilising reflectance spectroscopy in geological research. We describe variety available spectral libraries together with providing examples diagrams, and explain the basic ranges. Geologists can use different methods data collection, for example, sensors mounted on satellites, airborne [including unmanned aerial vehicle (UAV) platfo...

in this work‎, ‎we formulate chatterjea contractions using graphs in metric spaces endowed with a graph ‎‎and‏ ‎‎‎‎investigate ‎the ‎existence‎ ‎of ‎fixed ‎points ‎for such mappings ‎under two different hypotheses‎. we also discuss the uniqueness of the fixed point. the given result is a generalization of chatterjea's fixed point theorem from metric spaces to metric spaces endowed with a graph.

The list of published geological reports on the IskutSulphurc& gold camp continues to grow. The regional geologic framework has been prcsentcd by Anderwn (IYXY), Anderson and Thorkelson (IYYO) and Anderson and Bevier (1990). The geology and mineralization of the Sulphurets, Unuk and Snippaker areas have been described in maps and repwts by Alldrick and Britton ( 1988). Alldrick rf ul. (IYXY, IY...

The existence of diagnostic features in the visible and infrared regions makes it possible to use reflectance spectra not only identify mineral assemblages but also for calibration classification satellite images, considering lithological and/or mapping. For this purpose, a consistent spectral library with target minerals rocks is needed. Currently, there big market pressure raw materials inclu...

The southern part of Skull Valley has potential for shallowly buried mineral deposits. The most likely deposit type is either skarn/porphyry copper deposits, perhaps with surrounding polymetallic lead-zinc-silver replacement deposits or "distal disseminated" gold-silver deposits. The area (1) is structurally complex with both thrust and high-angle faults, (2) contains lithologic units favorable...
