Mineral prospectivity mapping for Gejiu tin district using random forest and convolutional neural network methods
The Gejiu district, the world’s most economically significant primary tin producer, served as our test area for developing an advanced mineral exploration targeting system integrating multi-source geospatial data with machine learning. In this paper, we constructed an exploration target model for…

The study of the magnetic anomaly variation A and its relationship with iron ores
Accurately and rapidly determining the relationship between induced magnetization (Mi) and remanent magnetization (Mr) of magnetic anomaly sources remains a critical challenge in magnetic exploration. It directly affects the reliability of geological interpretations inferred from magnetic survey…

Integrated EMIT and PRISMA hyperspectral analysis for mapping high-potential zones of epithermal Cu–Au–Ag sulfide deposits in the Saveh-Yazd copper metallogenic zone, central Iran
Exploration of epithermal Cu–Au–Ag deposits in the Saveh-Yazd copper metallogenic zone, within central Urmia-Dokhtar magmatic arc, Iran, is hindered by complex alteration patterns and structural overprinting. To address this, a novel integration of hyperspectral satellite data from EMIT (Earth…

Noise sensitivity analysis of mineral prospectivity models based on root mean square, geometric average, and isolation forest integration methods
There are a variety of multicriteria decision-making approaches to pinpoint the areas with significant mineral potential. Since exploration data need to be weighted or transformed into the same range before integration, and because there are multiple approaches to weighting, the chosen weighting…

Vertical variability of geochemical, petrophysical, and rock mechanical properties in upper Cretaceous organic-rich carbonate source rocks, Jordan
Immature organic-rich carbonate source rocks are widespread in sedimentary basins, serving as major oil shale resources and as analogs for thermally mature unconventional plays. Determining their baseline petrophysical and geomechanical properties prior to hydrocarbon generation is essential for…

Geological, mineralogical, and geochemical characteristics of the sedimentary sequence hosting the Khourmo stratabound copper deposit in Central Iran: Implications for its nature and tectonic setting
The Khourmo Cu deposit is located in the northeastern part of the Ravar Copper Belt (RCB), near the southwestern edge of the Tabas Block, situated within East-Central Iran. Copper exploration activities in this region have focused on three mining blocks: A, B, and C. The Khourmo deposit is…

Tracing rare earth elements distribution and enrichment mechanism in phosphorites of the Paleoproterozoic Bijawar Group in Mardeora Mine, Chattarpur district, Madhya Pradesh (M.P.), India
This study investigates the distribution and enrichment patterns of the rare earth elements (REEs) in phosphorites from the Hirapur Formation of the Paleoproterozoic Bijawar Group in the Mardeora area, Madhya Pradesh, India. The geochemical analysis of phosphorite samples reveals that the total REE…

Empirical relationships between magnitude and liquefaction distance using the Philippine dataset
Earthquake-triggered liquefaction can cause ground failure and damage to built-up structures. It is therefore necessary to determine the possible extent of the hazard during earthquakes. A common approach in predicting liquefaction occurrence is to relate the earthquake magnitude with its maximum…

Petrogenesis of highly fractionated S-type granite in the Longling area, southwest China: Implications for tectonic settings and mineralization
A systematic study of highly fractionated S-type granites enhances our understanding of tectonic evolution and rare metal mineralization. The Longling granites are surrounded by several rare metal deposits. Zircon U-Pb ages, whole-rock geochemistry, ore-forming elements, and Sr-Nd-Pb isotopic data…

Genesis of saltpeter deposits in karst caves in Southwest China
Saltpeter deposits preserved in karst caves are large and widely distributed in southwest China. These deposits historically served as the principal source of saltpeter for traditional gunpowder production in pre-industrial China. Despite their long mining history, the sources and enrichment…

Paleostress analysis on Paleozoic syn-depositional faults in the eastern Alborz, northern Iran
The Alborz Mountains of northern Iran stand out as an exceptional site for studying the Ediacaran-Paleozoic evolution of the northern Gondwana margin. The Alborz forms the inverted continental shelf of the Central Iranian microcontinent that was part of the northern Gondwana margin until the…

Magmatic evolution and mineralization of the Eocene back-arc magmatic rocks from NE Iran
The Eocene magmatism in NE Iran represents a significant component of the broader Cenozoic magmatic activity associated with the subduction of the Neotethys Ocean beneath the Iranian plateau. This study focuses on the petrogenesis, geochronology, and mineralization of magmatic rocks from the Nokeh…

Changes in crater lake chemistry after the 2021 eruption at Aso Volcano, Japan: insights from UAV-based hot water sampling
Several volcanoes in Japan have summit craters filled with water, including Zao, Kusatsu-Shirane, Kirishima, and Aso volcanoes. Aso Volcano, located in central Kyushu, is an active caldera volcano with a crater lake whose water volume varies from nearly zero to full capacity depending on volcanic…

Structural and geochronological constraints on the Permo-Triassic tectonic evolution of the southern Jinsha Orogenic Belt, eastern Tibetan Plateau
The southern Jinsha Orogenic Belt records the subduction-accretion-collision processes during the closure of the Paleo-Jinsha Ocean. Detailed structural analysis conducted along this belt and U-Pb zircon dating of tectonic-related plutons put robust constraints on a three-stage deformation history…

Novel regional–residual anomaly separation technique for evaluating Moho configuration and crustal density structure beneath the East Vietnam Sea (South China Sea)
This study presents a novel gravity anomaly separation technique and demonstrates its application in delineating the crustal density structure and Moho depth configuration of the East Vietnam Sea (South China Sea). The proposed method employs correlation analysis between Bouguer gravity anomalies…

Morphogenesis of the Holocene coastal landforms on Sumba Island, Indonesia
Coastal terraces, whether erosional, depositional, or bio-constructed, have been widely used to quantify Late Cenozoic vertical deformation and relative sea-level changes. Here, we review and investigate the Holocene coastal terraces of Sumba Island, Indonesia. We describe fifteen coastal sites…

Cenozoic exhumation of the North Qinling Range: Insights from apatite and zircon (U-Th)/He thermochronology
The Cenozoic uplift of the North Qinling Range has profoundly influenced climatic and ecological patterns across northern and southern China. However, key aspects of this orogenic event, including its principal phase(s) of exhumation, total magnitude, and detailed evolutionary processes remain…
