“…Surely the anomalous contents of these elements in the soils explains this transfer of non-essential elements to the Q. ilex specimens. However, Sb does not show high variation coefficients, probably due to the low mobility of this element in a semi-arid climate, as shown by Esbrí et al ( 2023 ). Multielemental content data for holm oaks are not abundant in the scientific literature; thus, the works of Higueras et al ( 2016 ) and Monaci et al ( 2022 ) were chosen as a comparison due to their similarities in the study area in physiographic and mineralogical terms.…”

“…The application of biogeochemical prospecting for Sb is of particular current interest as it is an element which has been declared a critical raw material by the European Union and the prospecting of its deposits is a priority for the European continent (UE 2020 ). Given the low mobility of this element in the typical semi-arid climates of the Iberian Peninsula (Esbrí et al 2023 ), the use of Quercus ilex leaves could delimit geological or lithological domains in which to focus prospecting efforts in other matrices (soils or sediments) or techniques (geological, geophysical, machine learning, etc.).…”

“…The area is also characterized by the notable presence of metallic ore deposits, none of which are currently active: the Almadén syncline hosts the Almadén Mercury Mining District (AMMD), which has been the most important producer of this element worldwide (Saupé et al 1990; Hernández et al 1999 ); the Guadalmez syncline hosts some minor Pb–Zn and Sb vein-type deposits (Gumiel & Arribas 1987 ); and the Valle de Alcudia anticline hosts a large number of medium-importance Pb–Zn-Ag vein deposits, described by Palero et al ( 2003 ). The Sb deposits in the Guadalmez syncline are presently the target of detailed studies due to a renewed interest in this element by the European Union, who consider it to be a “critical raw material” (UE 2020 ), and has promoted a number of studies concerning this element in the southern Central Iberian area (Álvarez-Ayuso et al 2022 ; Barquero et al 2022 ; Esbrí et al 2023 ) in the context of the AUREOLE (tArgeting eU cRitical mEtals (Sb, W) and predictibility of Sb-As-Hg envirOnmentaL issuEs) project, funded by the European ERA-MIN3 program.…”

The soil–plant transfer of trace elements is a complex system in which many factors are involved such as the availability and bioavailability of elements in the soil, climate, pedological parameters, and the essential or toxic character of the elements. The present study proposes the evaluation of the use of multielement contents in vascular plants for prospecting ore deposits of trace elements of strategic interest for Europe. To accomplish this general goal, a study of the soil–plant transfer of major and trace elements using Quercus ilex as a study plant has been developed in the context of two geological domains with very different characteristics in geological terms and in the presence of ore deposits: the Almadén syncline for Hg and the Guadalmez syncline for Sb. The results have made it possible to differentiate geological domains not only in terms of individual elements, but also as a combination of major and trace elements using Factor Analysis. The bioconcentration factors have demonstrated the uptake of macronutrients and micronutrients in very high concentrations but these were barely dependent, or even independent of the concentrations in the soil, in addition to high values of this factor for Sb. The Factor Analysis allowed for the differentiation of geogenic elements from other linked to stibnite ore deposits (Sb, S, and Cu). This element (Sb) can be uptake by Quercus ilex via the root and from there translocating it to the leaves, showing a direct relation between concentrations in soil and plants. This finding opens the possibility of using Quercus ilex leaves for biogeochemical prospecting of geological domains or lithological types of interest to prospect for Sb deposits.

La presente investigación tuvo como objetivo realizar un análisis bibliométrico profundo y detallado sobre la interrelación entre "Minería" y "Medio ambiente". De un total inicial de 56,329 documentos en Scopus, la investigación se centró en temáticas específicas relacionadas con la ingeniería, culminando en 3,742 documentos de relevancia. Mediante el uso de las herramientas avanzadas VOSviewer y Bibliometrix, se construyó un mapa de conocimiento ilustrativo, poniendo de manifiesto conexiones esenciales entre autores, con Abraham, J. y Kimijima, S. emergiendo como figuras líderes en el campo de la minería y medio ambiente. Se identificaron instituciones claves y colaboraciones internacionales, subrayando la prominencia de la Universidad Al-Farabi Kazakh National. Notablemente, se registró un incremento significativo en la producción académica durante el año 2023. Además, se detectó una inclinación en el uso de términos como "Mining", "Heavy Metals" y "Environment". Este estudio enriquece la literatura existente, subrayando tendencias emergentes, líderes destacados y nexos fundamentales en el ámbito de la minería y el medio ambiente.

“…In the Guadalmez syncline, the areas richest in Pb were found to coincide with the Sb maximum. It is not clear whether the presence of Sb and Pb has a genetic relationship or whether small Pb mineralizations were emplaced where Sb deposits would later form, but the result is that the weathering of secondary Sb-Pb minerals occurred [33]. Figure 5 offers the spatial distribution of the most relevant trace elements: Hg, Sb, Pb, and As.…”

The geochemical data from surface soils are often neglected or questioned when prospecting for ore deposits within active mining districts due to the “background noise” produced by anthropogenic pollution derived from mining activity. Large datasets on a national and international scale offer interesting possibilities to discover prospective zones. In the present work, data from the Geochemical Atlas of Castilla–La Mancha were treated in an area with an intense history of mining Hg, Pb, Zn, and Sb: the Almadén and Guadalmez synclines and the Alcudia Valley. The sampling grid was densified to adapt it to the scale of the main geological formations, and a cluster analysis was carried out to establish the relationships between the variables and a factor analysis to distinguish between geogenic and metallogenic factors. The results showed very high concentrations of some elements of prospective interest in local background areas: Hg (51 mg kg−1), Pb (1190 mg kg−1), and Sb (45 mg kg−1), with high variation coefficients. Cluster analysis unveiled a relationship between most of the local ore-forming metals (As, Sb, Hg, Pb, and Ag) with a clear correlation between Hg and organic matter, suggesting a notable contribution of Hg in soil. The factor analysis highlighted five factors, three geogenic and two ore-forming elements. Despite Hg being the main candidate to form a separate factor, its aerial deposition and a large number of outliers in the Almadén syncline contributed to integrating the element into a geogenic factor. Instead, factors F4 (Pb and Zn) and F5 (As and Sb) delimited the prospective areas in both synclines far from the known and the exploited mines. Some of these areas coincided with discovered mineralized zones, specifically in the area SE of a derelict Sb mine, confirming the usefulness of these datasets and statistical tools in areas with recent mining activity.
