a combination of elements is usually used in reconnaissance geochemical exploration and distribution maps are drawn to identify probable anomalies. in this study, 102 stream sediment samples from the arid environment of mesgaran area, eastern iran, were investigated using r-mode factor analysis. a four-factor model with a cumulative variance of 75.90% clearly indicated group associations of the...
the investigated area is located 30 km south of sabzevar in halakabad village. geological phenomenons in area follow a trend of nw-se. mineralization consists of metallic and non-metallic (kaolin) mineralization. disseminated and veinlet mineralization is generally associated with argillic alteration type. pyrite is the most widespread type of sulfide mineralization in halakabad occurrences. it...
Geochemical gene is a new promising concept proposed recently in the discrimination and traceability of geological materials also useful tool to recognize geochemical anomalies mineral exploration. Based on lithogenes LG01 LG03, can be classified into nine types LG_CR compositionally. With respect with 11 LG_CR, order eliminate lithological influence further narrow prospecting target area, tung...
This study focus on the characterization of hydrocarbon microseepages in the northern Tucano Basin (Bahia State, Brazil), using geostatistical analysis of regional hydrocarbon geochemical data yielded from soil samples and digital processing of Enhanced Thematic plus (ETM+/Landsat7 satellite) and Advanced Spaceborne Thermal Emission and Reflection Radiometer imagery (ASTER/Terra satellite). A t...
The Bonaparte project is a new multi-year bedrock mapping program of the British Columbia Geological Survey (BCGS) concentrating on Mesozoic arc volcanic and plutonic rocks of the Quesnel Terrane in the northeastern part of the Bonaparte Lake (92P) map sheet (Figure 1). The area encompasses a northwest-trending belt of high mineral potential that includes a number of interesting mineral occurre...
Geochemical data can reflect geological features, making it one of the basic types geodata that have been widely used in mineral exploration, environmental assessment, resource potential analysis and other research. However, final decisions regarding activities are often limited by spatial accuracy geochemical data. sampling is sometimes difficult to conduct because harsh natural geographic con...
The fixed-wing time-domain airborne electromagnetic method (FTEM) has been widely used in metal mining exploration, groundwater mapping and other fields worldwide, recent decades, its use gradually also become more prevalent China. first generation of the system (iFTEM-I), researched developed by Institute Geophysical Geochemical Exploration (IGGE), demonstrated years. In this article, we intro...
The lunar geological record contains a rich archive of the history of the inner Solar System, including information relevant to understanding the origin and evolution of the Earth-Moon system, the geological evolution of rocky planets, and our local cosmic environment. This paper provides a brief review of lunar exploration to-date and describes how future exploration initiatives will further a...
the closed nature of geochemical data has been proven in many studies. compositional data have special properties that mean that standard statistical methods cannot be used to analyse them. these data imply a particular geometry called aitchison geometry in the simplex space. for analysis, the dataset must first be opened by the various transformations provided. one of the most popular of the a...
