“…To meet the challenge of adapting the reflection seismic methods and tools developed for stratified sedimentary environments to strongly scattering crystalline rocks, data processing and imaging during the pre-stack and post-stack sequence required special attention to enhance the reflection signals (Wu et al, 2020). The main seismic data processing technologies used in this project are as follows.…”

Prospecting for and exploiting buried mineral deposits is currently challenging. Given their high precision and resolution, reflection seismic methods might be useful in such applications involving deep mineral deposits. However, there are few open seismic datasets available from mineral deposit exploration, especially in hardrock environments. The world‐class Caosiyao porphyry Molybdenum deposit (1.76 Mt) in the Jining area of Inner Mongolia, China, is largely covered by loess layers, which poses challenges to its exploration. Seismic reflection surveys were conducted in to help delineate the deep granite porphyry intrusions and associated orebodies. This paper presents the raw seismic reflection dataset from three profiles on the Caosiyao deposit area, which can be used as a standard dataset for reflection seismic processing in shallow coverage and hardrock areas. Situated at the juxtaposition of the Khondalite Belt and the Trans‐North China Orogen in the northern North China Craton, the Jining region hosts considerable known porphyry Mo deposits. As such, this open dataset can assist research on deep geological structures and hence increase prospecting efficiency in geologically similar areas.

“…In recent years, geophysical explorations, remote sensing, and other prospecting methods have played important roles. Various methods have been successively applied to the investigation of metal mineral deposits, such as resistivity methods; highprecision magnetic methods; shallow seismic methods; transient electromagnetic (TEM) methods; controlled-source audio frequency magnetotelluric (CSAMT) methods, and so on (Xue et al, 2012;Manzi et al, 2013;Di et al, 2018;Di et al, 2020;Wu et al, 2020). Li et al (2002) used an electrical sounding method to detect concealed bauxite in loess-covered areas of Henan Province, and successfully inferred the shapes and spatial positions of the bauxite deposits.…”

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