Significant Crustal Losses During Mountain Formation Revealed by New Research
Recent research reveals that significant portions of continental crust may have been lost to the mantle during the formation of major mountain ranges, including the Himalaya-Tibetan Plateau, European Alps, and Zagros Mountains. Led by Dr. Ziyi Zhu from Monash University, the study published in Earth and Planetary Science Letters quantifies this loss, highlighting that up to 64% of the crust in the Zagros Mountains and 50% in the European Alps may have been destroyed. Understanding these geological processes is crucial for interpreting Earth’s tectonic history.
New Model Reveals Deformation Mechanisms of North China Craton
A recent study published in Nature Geoscience reveals the geodynamic mantle-flow model explaining the deformation of the North China Craton (NCC). Led by Professor Shaofeng Liu, the research uncovers the impact of the Izanagi plate’s subduction on NCC’s decratonization, offering insights into tectonic interactions and implications for seismic hazards in Northeast Asia.
New Research Challenges Stability of Earth’s Ancient Cratons
Recent geological studies reveal that Earth’s ancient crust, known as cratons, is undergoing significant changes, challenging long-held beliefs about their stability. Research on the North China Craton highlights dynamic processes leading to ‘decratonization,’ reshaping our understanding of geological stability and the evolution of Earth’s crust.
Study Reveals Ancient Origins of Earth’s Continents
Scientists have long been puzzled by the formation of the Earth’s continents, and a new study from the University of British Columbia sheds light on this ancient mystery. The study reveals that the first continents were likely formed through the…
