Linking Mineral Science to Geological Processes 
Home: About



Clay minerals play a pivotal role in various geological materials, making them a captivating area of study. Their presence in diverse environments, constantly influenced by human activity, has sparked significant interest across different fields, such as oil and petroleum research, environmental studies, and radioactive waste management. Wherever water and rock converge, clay minerals emerge as common byproducts of weathering, holding immense potential in the diagenetic evolution within sedimentary basins during sediment burial. The impact of clay minerals on hydrocarbon reservoirs cannot be understated, greatly influencing petroleum production efficiency. Moreover, they assume a crucial role in hydrothermal and weathering ore-forming processes, especially concerning the formation of strategic trace elements deposits. Our research focuses on exploring various geological contexts, ranging from deep sedimentary basins to weathering profiles, as we delve into the intricate structure, crystalochemistry, and reaction mechanisms that underlie the formation of clay minerals and related mineralizations


Sedimentary basins

Surface weathering and shallow diagenetic processes give birth to clays, which undergo transformative changes, ultimately leading to the development of mature clay mineral assemblages nestled within deep-seated sedimentary layers. In subduction zones, the breakdown of clay minerals unleashes a hydrous component that plays a crucial role in magma generation. Once igneous rocks are formed, they undergo weathering and recycling, giving rise to new clay minerals, thus completing the captivating magma-to-mud pathway of the clay cycle. In sedimentary basins, diagenetic reactions strive for heightened thermodynamic stability, a subject extensively explored since the 1970s in relation to diagenesis and quality prediction of conventional reservoirs. The advent of modern analytical tools has revolutionized the precise quantitative and qualitative characterization of nano-pores and mineralogy in fine-grained shale, ushering in a new era of studying clay minerals and their invaluable contribution to the exploration of unconventional reservoirs. Our current investigation focuses on Paleozoic mudrocks sourced from the Mid-Continent Anadarko and Permian basins, where we seek physico-chemical clues that shed light on the intricate mechanisms governing clay mineral evolution in deeply buried shaley strata

Weathering and trace-element mineralization

Trace elements, especially rare earths (REE), are vital in modern technologies and industrialized nations' lifestyles. Their applications are ubiquitous and indispensable. While major REE deposits are typically in weathered granitic crust, our research pioneers by focusing on volcanic ash. We employ in-situ geochemical micro-analyses of glass shards and immediate clay alteration products. Trace elements in clays reside on broken edge sites or negatively charged siloxane surfaces, forming adsorbed complexes with clay minerals. Our research examines the intricate behavior and distribution of REEs, considering local geology factors like Eh, pH, water-rock interaction, trace element complexation, and clay particle morphology. Understanding the distribution of REEs within clays formed on rare earth-bearing igneous substrates aids in identifying promising regions for future exploration. Through our endeavors, we aim to unlock insights shaping the future of REE exploration.

The alteration intensities within hydrothermal systems have been found to exhibit intriguing heterogeneity. It's fascinating to observe how rocks bear evidence of multiple modification events, each leaving its unique imprint characterized by specific temperature conditions and the composition of catalytic fluids involved. The outcome of hydrothermal impact is a diverse array of alteration assemblages dominated by  hydrous phases such as clay minerals. Phyllosilicates serve as a particularly useful tool in evaluating the conditions and nature of reacting fluids and readily form the distinct alteration zones useful for vectoring towards valuable epithermal mineralizations. Our current research showcases the role of chlorite minerals and their trace element budget providing inferences on the controlling variables on REE mobility in hydrothermal systems.
