This study presents a novel analysis of a hailstone collected near Cordoba, Argentina, quantifying the composition, size distribution, and potential sources of non-soluble particles contained within. The hailstone contained diverse particles, with sizes ranging from 1.9 to 150.3 µm, primarily carbonaceous, including in the center, suggesting a possible biological and geological influence on hail formation. Silicate particles were distributed throughout the hailstone, likely from eroded soil and agricultural activities. Finally, salts were detected in the outer layers of the hailstone and may have originated from the nearby salt lake. This study highlights the regional influence of various land use types on hail formation and growth and points to the potential impacts of natural and anthropogenic factors on hailstone composition.
