lag is a general term applied to coarse grained (> 2 mm), hard, but partially weathered rockfragments, which are concentrated at the surface through attrition of finer materials. based on morphology,mineralogy and the origin of lag from the cobar region of australia, lag may be conveniently grouped intothree broad morpho-mineralogical categories; (a) those with a rough, blocky, lithic morpholog...

Abstract—Accurately positioning detection of concealed deposits or ore-bodies is one of the difficult problems in mineral exploration field. Theory calculation and exploration practices for tunnel gravity indicate that 3D high-precision Tunnel Gravity Exploration Method (TGEM) can find concealed high-density three-dimensional ore-bodies in the depth. The ore-finding breakthroughs at the depth o...

A bidimensional empirical mode decomposition (BEMD) program on a MATLAB platform was effectively used to handle gravity signals for the Tongshi gold field. This yielded a two-dimensional intrinsic mode function (IMF3) image that meticulously depicts the spatial distribution relationship between various gold deposits and the different geological units of the gold field. By combining the IMF3 ima...

In recent decades, the human demand for mineral resources has increased dramatically, and mining of shallow deposits basically been completed. The prospecting direction turned to concealed deposits. For this reason, various penetrating geochemical methods have developed find minerals a series exploration techniques proposed. At same time, use gene as new technique presented in years is feasible...

Abstract Stable isotope data from hypogene (i.e., below the line of weathering) iron oxides and gangue minerals BIF-hosted ore deposits in Australia, South Africa, Brazil have significantly assisted constraining different hydrothermal fluid sources flow models during upgrade BIF to ore. The δ 18 O values on paragenetic stages enrichment display a consistent decrease unenriched (4–9‰) as low −10...

With the increase of exploration depth, it is more and difficult to find Au deposits. Due limitation time cost, traditional geological methods are becoming increasingly be effectively applied. Thus, new ideas urgently needed. This study assessed feasibility effectiveness using hyperspectral technology prospect for hidden For this purpose, 48 plant (Seriphidium terrae-albae) soil (aeolian gravel...

the purpose of this study is the fusion of polarimetric sar and hyperspectral images for concealed target detection in forest areas. the proposed method is using the polarimetric and the spectral signatures. a radarsat-2 image and a hyperion image of the city san francisco were chosen for evaluation of the proposed method. the four targets were selected in the forest and the outer areas. three ...

Turbidite fans, serving as good reservoirs for petroleum accumulation, are typically formed during deep faulting periods in continental basins, particularly steep slope zones. However, gentle zones also significant and unique the formation of turbidite fans. These fans hold immense importance exploring concealed lithological reservoirs. Taking Chezhen Depression Bohai Bay Basin an example, we c...
