چکیده
Multi-element data for three Regional Geochemical Surveys covering approximately 45 000 square kilometres of central British Columbia were released on July 7, 1992. These data comprise the re-release of date from two previous surveys in NIPS map sheets Taseko Lakes (920) and Bonaparte Lake (92P). new data based on the analysis (by neutron activation) of archived streatn sediment from these surveys, and the results of a new survey conducted in NT!? map sheet Mount Vaddington (92N) during the 1991 field season (Jackaman rr N/., 1992a. b, c). Over I21 000 analytical determinations on samples from 2568 sites are represented in these threr map areas. This study details the investigation of sewn watersh:ds hosting anomalous RGS wrple sites wilt in the ~1992 Regional Geochemical Survey release area v hich hwt no known minrraliration and were unstaked (sa ‘e one) as of July 7, l9Y2 (release day). The abjectivr of the study wa:; to determine the origin of the anomalies and, if n< It attributable to a bedrock source, assess thei.r impact on the Regiorlal Geochemical Survey program.

Using stream sediment data to determine geochemical anomalies by statistical analysis and fractal modeling in Tafrash Region, Central Iran
Iranian Cenozoic magmatic belt, known as Urumieh-Dokhtar, is recognized as an important polymetallic mineralization which hosts porphyry, epithermal, and polymetallic skarn deposits. In this regard, multivariate analyses are generally used to extract significant anomalous geochemical signature of the mineral deposits. In this study, stepwise factor analysis, cluster analysis, and concentration–...
متن کاملApplication of continuous restricted Boltzmann machine to detect multivariate anomalies from stream sediment geochemical data, Korit, East of Iran
Anomaly separation using stream sediment geochemical data has an essential role in regional exploration. Many different techniques have been proposed to distinguish anomalous from study area. In this research, a continuous restricted Boltzmann machine (CRBM), which is a generative stochastic artificial neural network, was used to recognize the mineral potential area in Korit 1:100000 sheet, loc...

This report discusses the geology and mineral potential of a segment of the Coast Mountains, east of Princess Royal Island (in NTS area 103H) termed the Khutze River area. The information presented is based on public domain reports and old staking records. In 1999, a regional stream sediment survey was conducted in the area by the Ministry of Energy and Mines. The results of the geochemical sur...
متن کاملSeparation of Geochemical Anomalies Using Factor Analysis and Concentration-Number (C-N) Fractal Modeling Based on Stream Sediments Data in Esfordi 1:100000 Sheet, Central Iran
The aim of this study is separation of Fe2O3, TiO2 and V2O5 anomalies in Esfordi 1:100,000 sheet which is located in Bafq district, Central Iran. The analyzed elements of stream sediment samples taken in the area can be classified into 5 groups (factors) by factor analysis. The Concentration–Number (C-N) fractal model was used for delineation of the Fe2O3, TiO2 and V2O5 thresholds. According to...
