A Metallogenic Model for Bauxite Deposits and Geophysical Prospecting Methods: Using the Sedimentary Type in Northern China as an Example

چکیده
An ideal metallogenic and prospecting model has important guiding significance for aluminum ore development geophysical exploration. Previous research in this field only focused on body evaluations belts. Selection of reasonable methods exploration bauxite deposits is still challenging. To solve these problems, a new based the geological information established firstly. The ore-bearing rock bodies sedimentary are strictly controlled by paleo-topographic conditions. undulating shapes paleo-topography control scales series bodies. Then, different applied deposit analyzed petrophysical measurement. For areas with thick overburden large buried depths, it was found that fixed-loop transient electromagnetic (TEM), high-precision gravity, seismic were most effective. In regard to thin small direct current (DC) sounding, exploration, TEM considered be However, very shallow DC sounding deemed more suitable. This study selected actual processes Wanggudong mining area western Henan as an example, application method sedimentary-type successfully introduced.
