معرفی
Dr. Hanika Rizo is a researcher in the Department of Earth Sciences at Carleton University, part of the Faculty of Science. Her research focuses on the early geochemical evolution of the Earth, particularly processes occurring over 4 billion years ago, such as core formation and mantle evolution. She employs isotopic systems like 182Hf-182W to analyze mantle-derived rocks, emphasizing projects in the Saglek-Hebron Complex, Northern Labrador. Dr. Rizo teaches Geochemistry and Geochronology (ERTH 3003) and Advanced Isotope Geochemistry (ERTH 4803), and advises students in Chemistry and Earth Sciences programs. She is affiliated with the Herzberg Laboratories in Ottawa, Ontario.
Her research team investigates rare pre-3.6 Ga mantle-derived rocks, including zircons older than 3.8 Ga. Key projects include understanding stagnant and mobile-lid tectonic regimes and abiotic carbon synthesis in Eoarchean metasedimentary rocks. She explores tungsten isotopes in plumes and mantle heterogeneity preservation through studies like the Onega Basin picrites and Pilbara Terrane basalts.
Dr. Rizo’s work bridges geochemical analysis with field studies, addressing fundamental questions about Earth’s formation and early dynamics. She collaborates on projects involving Fe and S isotopes in ore deposits and dinosaur paleontology, showcasing interdisciplinary reach. No scientific awards are listed, but her contributions to mantle evolution and early Earth geochemistry are well-documented in peer-reviewed publications.
