Geochemistry: Exploration, Environment, Analysis (2014) 14 (4): 359–367.
... is to identify the vertical distribution features of elements in the regolith over the Jinwozi gold field, NW China by using factor analysis (FA) and concentration-volume (C-V) fractal modeling based on the data-set generated from 70 overburden drilling boreholes. Firstly, the zones of different gold enrichment...

.... There is a critical need to study the vertical distribution of elements in the regolith, and to determine potential mechanisms for transferring elements from the ore body upwards through regolith cover to the surface, and to establish appropriate sampling media and analytical methods. The Jinwozi gold deposit, which...

... regia extractions of soils and vegetation, and MMI-M extraction of soils were effective by providing strong, coherent multi-element anomalies at relatively close spacing (50 m). Conversely, portable XRF analysis was less effective at this site as the elemental concentrations were too low. Gold...

... concentrations of Au (maximum 29 ppb; median 2 ppb; n = 835) are spatially related to either Archean greenstones or unconformity-related uranium – base metal – gold mineralization. Although some samples with anomalous Au concentrations are carbonate-rich, there is no consistent relationship between elevated Au...

... sampling was carried out in an area of c. 150 000 km 2 at a density of one sample per 100 km 2 . Samples were collected from the weakly cemented sandy clay-rich horizon at a depth of 15–30 cm and sieved to <120 mesh in the field. The sieved samples were ground to 200 mesh (75 μm). Thirty-four elements...

... rocks together with cherts and tuffs. Most prominent are gabbros and large volumes of basaltic lavas. These mafic rocks have high TiO 2 contents, flat rare earth element (REE) patterns and show high-field-strength elements (HFSEs) similar to those of mid-ocean ridge basalts (MORB). The mafic rocks...

... determined. Intriguing patterns, such as a strong depletion of the average gold value for the middle crust (0.66 ppb vs. 1.5–1.6 ppb in the upper and lower crust), may hold implications for workers in the field of economic geology. An excellent overview on continental basalts is quite useful for a modern-day...
