Dear mineralogists: We invite you to submit an abstract to our session at IMA 2026 Meeting in Nanjing, China (August 20-24, 2026). 11.5 Fe-oxide and Fe-oxyhydroxide minerals: from molecules to mountain building<https://ima2026.nju.edu.cn/52/c8/c65014a807624/page.psp> Fe-oxide and Fe-oxyhydroxide minerals play important roles in geological and environmental systems. We invite submissions in the following areas: (1) structure, chemistry, magnetic property and phase transformation of Fe-oxide and Fe-oxyhydroxide minerals, (2) roles of dissolved silica and silicate minerals on stability and transformation kinetics of Fe-oxide and Fe-oxyhydroxide minerals, (3) formation processes of Fe-oxide and Fe-oxyhydroxide minerals in Precambrian iron formations, hydrothermal ore deposits, sedimentary and igneous rocks.
