About the Lab
Professor Young-Sook Heo's research lab specializes in geochemical and isotope geochemistry, focusing on weathering processes, ocean circulation, and the biogeochemical cycling of elements in terrestrial and marine systems. The lab investigates the behavior of lithophile and rare earth elements, particularly lithium and neodymium isotopes, to reconstruct past climate and ocean circulation dynamics. Key research directions include silicate weathering rates, paleo-oceanographic reconstructions using authigenic neodymium isotopes, and the role of atmospheric deposition in soil formation. The lab integrates field sampling, high-precision isotope analysis, and geochemical modeling to understand Earth surface processes across climatic and tectonic timescales.

15We examined the pedogenic behavior of lithium (Li) and its isotopes in Hawaii by sampling same‐age lava flows under mean annual rainfall ranging from 18 to 300 cm. Lithium concentrations in these soils vary from 1 to 29 ppm. Whereas Na, K, and Ca are completely leached from the soil at the most humid and severely weathered site, Li, Mg, Si, and Al show significant retention due to their association with secondary clay minerals. In these soils, allochthonous Li delivered in marine and mineral aer
Antarctic snow preserves an atmospheric archive that enables the study of global atmospheric changes and anthropogenic disturbances from the past. We report atmospheric deposition rates of platinum group elements (PGEs) in Antarctica during the last ∼ 50 years based on determinations of Pt, Ir, and Rh in snow samples collected from Queen Maud Land, East Antarctica to evaluate changes in the global atmospheric budget of these noble metals. The 50-year average PGE concentrations in Antarctic snow
