Seminar: Giovanni Aloisi "Stable isotope tracers from Earth System Science to human physiology"
Stable isotopes are used as tracers of geo(bio)logical processes and are an effective tool for deciphering the evolution of the Earth System over time. Key concepts in this approach include isotopic mass balance, isotope mixing, and thermodynamic and kinetic isotope fractionation. Recently, stable isotopes have been applied in human physiology—the study of functions and processes in the human body—to investigate a wide range of pathologies, such as osteoporosis, cancer, and kidney diseases. I will present examples from both the earth and medical sciences to demonstrate how these fundamental isotope concepts bridge the gap between these seemingly disparate disciplines. In the earth sciences, I will address the processes that led to the late-Miocene emplacement of the Mediterranean Salt Giant, one of Earth’s largest and most recent giant salt deposits. Chloride isotopes (37Cl/35Cl) in halite support the hypothesis that an exceptional sea-level drawdown event (~2 km) was associated with the accumulation of the Mediterranean salt layer, while multiple sulfur isotopes (34S/32S and 33S/32S) suggest microbial processes may have contributed to the formation of marginal gypsum deposits in the Vena del Gesso (central Apennines, Italy). In the medical sciences, I will show how calcium isotopes (44Ca/42Ca) are used to deduce whole-body bone mineral balance, an elusive quantity crucial for the early diagnosis of osteoporosis, and how dissolved chloride isotopes are used in exploratory studies to investigate the nature of certain kidney diseases. These examples illustrate that the modern separation between earth and medical sciences stems not from differences in underlying physical and chemical laws but from the complexity of the studied systems, which require a highly specialized training to be fully apprehended.
Seminars visiting researcher – Alejandro Fernandez-Martinez. Geochemistry and Mineralogy of Acid Mine Drainage (AMD)
AMD occurs in zones where pyrite formations are oxidized due to rock weathering, a phenomenon that is accelerated in the presence of mining operations. AMD waters are highly acidic, mobilizing metals and metalloids, among which many pollutants. These are present in many parts of the world, presenting important environmental concerns. Here, an overview of the phenomenon, and a detailed analysis using nanoscale techniques of the most important Fe and Al colloids formed in AMD, and their environmental relevance, will be presented.
Seminars visiting researcher – Alejandro Fernandez-Martinez. Mineral colloids in acid mine drainage: from toxic elements to critical elements
The acid mine drainage present in the Rio Tinto site from the Tartessian times represent a legacy of metal pollution of unprecedented importance due to the large volume and high concentrations of toxic elements mobilized. Here, an overview of the phenomenon, and a detailed analysis using nanoscale techniques of the most important Fe and Al colloids formed in AMD, and their environmental relevance, will be presented. Moreover, the acidity of AMD waters facilitates the mobilization of rare earth elements and valuable metals like copper, potentially paving the path for economically viable site restoration efforts.
Seminars visiting researcher – Alejandro Fernandez-Martinez. Mineral nucleation and growth in aqueous systems: unveiling the secrets of crystallization
In the last decade, the use of advanced characterization techniques at the nanoscale allowing to probe early stages of formation of minerals in supersaturated aqueous solutions has allowed the discovery of non- classical nucleation pathways. Here, an overview of old vs. new paradigms in the field of mineral formation will be given, presenting a state-of-the-art of the current physico-chemical understanding of precipitation phenomena.
Seminars visiting researcher – Alejandro Fernandez-Martinez. Synchrotron nanoscale characterization techniques for the Earth sciences
The Pair Distribution Function (PDF) technique, classically used to the study of liquids and amorphous materials, has seen a renewal interest due to the ability to collect quickly scattering patterns using 2D detectors at 4th generation synchrotron sources, with enough signal-to-noise ratio to be able to analyse the diffuse scattering coming from the disordered component of a material. This technique will be introduced and several examples in the field of mineral nucleation and growth, and of cement hydration, will be shown.

Mineral Evolution: A Case Study of a New Natural Law
The diversity and distribution of Earth's minerals have changed through 4.5 billion years as a consequence of varied physical, chemical, and ultimately biological processes. "Mineral evolution," the study of this rich history of change, has led to a new mineral classification scheme that complements the official system of the International Mineralogical Association. The new "Evolutionary System" of mineralogy attempts to place every mineral species in its historical setting and formational environment. In this way, minerals provide one vivid example of a much more general natural process. Indeed, a pervasive wonder of the natural world is the evolution of varied systems, from stars to minerals to life. These evolving systems seem to be conceptually equivalent in that they display three notable attributes: (1) they form from numerous components that have the potential to adopt combinatorially vast numbers of different configurations; (2) processes exist that generate numerous different configurations; and (3) configurations are preferentially selected based on function. We identify universal concepts of selection—static persistence, dynamic persistence, and novelty generation—that underpin function and drive systems to evolve through the exchange of information between the environment and the system. Accordingly, we propose a new law, the “law of increasing functional information”: The functional information of a system will increase (i.e., the system will evolve) if many different configurations of the system undergo selection for one or more functions. Mineral evolution is a revealing test case of this law.

Seminar: Sonja Aulbach “Properties of Earth’s mantle and subduction zone processes through time: The message from eclogite xenoliths” 07.06.2023
Kimberlite-borne xenolithic (“mantle”) eclogite has been studied for many decades. Given their origin as mid-ocean ridge basalt and gabbro, such samples can provide insights into the convecting mantle source from which their igneous protoliths were derived, and into the conditions during their subduction back into the mantle. Such applications are contingent on a good grasp of each individual sample’s multistage petrogenesis, comprising differentiation processes in the ocean floor, seafloor weathering, metamorphic reactions in palaeo-subduction zones, and overprint during their later extended residence in the lithospheric mantle. I will discuss what we can learn from eclogite xenoliths about the temperature and redox evolution of the convecting mantle from which their protoliths formed, about the supercontinent cycle from their age distribution, and about redox conditions and interactions with slab-derived liquids during their subduction in Archaean and Palaeoproterozoic time.

From the Theory of Ice Ages to IPCC climate projections - International Science Council, Maria Fernanda Sanchez Goni
Despite improved understanding of global and regional climate change and increased model complexity, the relative contribution of different feedbacks (clouds, ocean circulation, vegetation and its coupling with water and carbon cycles, ice…) continues to vary from model to model, leading to mismatches between climate reconstructions and simulations. Acquiring new Quaternary paleoclimatic records and comparing them with model results is, more than ever, the basic science needed to explain current climate change and improve climate projections. In this lecture, María Fernanda Sánchez Goñi, Professor of Paleoclimatology, will briefly introduce the discovery of the ice ages, the astronomical theory explaining them, and the unexpected identification of abrupt climate variability (millennial-to-centennial) in the 1980s. After summarizing the evolution of global climate over the last million year, she will show its impact on different regions of the planet. She will highlight the mismatch between past climates and model simulations and, in particular, the problems linked to modelling regional responses to past global climate changes, for example in monsoon regions. These issues have strong implications for future climate models, projections of sea level rise and regional impact of climate change. Basic research on the Quaternary is still needed to evaluate model simulations and improve climate projections.

Advances in Global Seismic Tomography With applications in Geodynamics and Mineral Physics
The concept of imaging Earth’s interior based on the full physics of seismic wave propagation was introduced approximately 35 years ago. Thanks to modern numerical methods and high-performance computers, seismic Full Waveform Inversion (FWI) has finally come to fruition in the past decade. Today, FWI is used across nine orders of frequency and wavelength, from megahertz frequencies and millimeter wavelengths in ultrasound medical imaging and nondestructive testing to millihertz frequencies and thousand- kilometer wavelengths in global seismology. The goal of FWI is to use every wiggle in a seismogram to understand the underlying physics. In this talk I give an overview of the status of global seismic waveform tomography, with applications to problems in geodynamics and mineral physics.
