Special Issue Information

Dear Colleagues,

“Digital geology” can be called a combination of “mathematical geology” and “information technology”, which is the data analysis component of geological science. Geological data science is a science that uses the general methodology of data to study geology based on the characteristics of geological data and the needs of geological works. The digital exploration and assessment of mineral resources manifest in the application of digital geology in mineral exploration to reduce ore-prospecting uncertainty and to improve ore-prospecting efficiency. The key digital geoscience knowledge lies in highly condensed information derived from raw geological, geochemistry, geophysics, and remote-sensing survey data, which can be used to derive quantitatively exact expressions of the underlying ore-forming processes, phenomena, and regularities. These scientific expressions can be used to predict the occurrence, development, and results of ore-forming events in geological time. Digital mineral exploration is a successful application of data geosciences combined with information technology in geosciences. This Special Issue of the first edition showcased mainly theories, methods, and achievements in digital mineral exploration and assessments in recent years. This Special Issue of the second edition will continue to show new research advances in digital mineral exploration and assessments.

The Jiaodong gold cluster region (JGCR) at the southeastern edge of the North China Craton (NCC), holding approximately 5000 t gold reserve, is the third largest gold cluster region in the world. The Bidimensional Empirical Mode Decomposition (BEMD) is applied in extracting gravity anomaly components showing deep geological architectures and geodynamics. The research results illustrate that (a) at a depth of about 27 km, there are three tectonic units, namely the mantle uplift (I) with gravity values ranging from 2 to 14 μm/s2, a mantle depression (II) with gravity values varying from 0 to −13 μm/s2, and a mantle flat (III) with gravity values ranging from −2 to 2 μm/s2. All giant gold deposits are distributed within the mantle depression. This implies that mantle uplift can trigger the concentration of hot, ore-forming fluids in mantle depressions, leading to the accumulation of large amounts of gold and the formation of giant deposits. (b) At about 17.1–12.5 km, there are three tectonic units: the Jiaolai–Jiaobei mantle uplift (I), showing a strong positive gravity anomaly with gravity values ranging from 1.5 to 10 μm/s2, the Sulu ultra-high pressure metamorphic block (II), displaying a negative gravity anomaly with gravity values ranging from −10 to −1.5 μm/s2, and the Jiaoxibei gold cluster region (III), exhibiting gravity background with gravity values varying from −1.5 to 1.5 μm/s2. (c) At about 8.9–5.3 km, there are a series of positive and negative gravity anomalies. Most granites with low density display negative gravity anomalies, among which there are some negative anomalies with positive anomalous edges which contain gold deposits. This illustrates an ore-forming pattern, a granite with negative gravity anomaly, around which there is alteration mineralization with positive gravity anomaly. Combined with other studies, it was concluded that the geological architectures at different depths as and the giant Jiaodong gold cluster region were formed by the asthenosphere upwelling triggered by NNW-ward subduction of the Izanagi Plate over a time period of approximately 200–100 Ma.
