The anomalous enrichment of the rare earth elements and yttrium (REY), U, Mo, As, Se, V in coal-bearing intervals intercalated within carbonate successions South China has attracted much attention due to highly promising recovery potential for these elements. This study investigates mineralogical geochemical characteristics late Permian (layers A–F) marine strata Xian’an Coalfield Guangxi Provi...

Detecting the mineralization component is one of the main subjects in geochemical exploration. Various techniques have been introduced to explore favorite zones and separate the anomaly from background, such as bivariate or multivariate statistical analysis. The main objectives is to identify the spatial variability and main sources of some special elements in Qare Char, in northwest of Iran, b...

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 Hawaiian hotspot is often attributed to hot material rising from depth in the mantle, but efforts to detect a thermal plume seismically have been inconclusive. To investigate pertinent thermal anomalies, we imaged with inverse scattering of SS waves the depths to seismic discontinuities below the Central Pacific, which we explain with olivine and garnet transitions in a pyrolitic mantle. Th...

Hanza region is located in the southern part of Urumieh–Dokhtar Metallogenic belt in southeastern Iran. This region includes six known porphyry copper deposits and it is considered as an ore- bearing region from geochemical point of view. The aim of this research is to examine effective processing techniques in the analysis of stream sediment geochemical datasets and ASTER satellite images. The...

The use of induced polarization (IP) methods in oil and gas exploration dates back to the 1930s, but the validity of anomalies has been difficult to establish. Although recent geochemical and downhole research has verified the source of IP anomalies in some geologic environments, the influence of cultural (anthropogenic) features on the electrical data remains a serious stumbling block to the a...
