Lithosphere and surface processes (LSP) integrates geological processes ranging in scales from microscopic to global, from fractions of a second to the age of the Earth.Tectonic processes shape the Earth’s surface through interactions among the deep interior, the lithosphere, the hydro-atmosphere, and the biosphere.

Lithospheric Processes cause magmatism, mantle dynamics, and faulting, which in turn shape the Earth’s ever-changing surface. We study the effects of Lithospheric Processes with a diverse set of tools. We measure and model young, active tectonic systems with apparent earthquake and landscape hazards.

2024年3月3日 · Our study presents an integrated lithospheric model for southeastern Australia and provides valuable insight into the mechanisms driving surface geological processes. The lithosphere is the Earth's outermost rigid layer and the focus of important geological processes, such as earthquakes, volcanism, and mineralization.

2023年4月13日 · We provide new insights into the geometry of the Alpine and Apennine belt systems, the compositional and thermal state of the lithospheric mantle, and the lateral (i.e., temporal) heterogeneity of the delamination and subduction process beneath the central Mediterranean area.

Understanding the processes that have influenced the development of Earth’s lithosphere requires the combination of field, geochronological, and geochemical techniques in a wide variety of temporal and spatial scales.

2023年12月15日 · Here, we track the lithospheric thickness history using machine learning based on global lithogeochemical data of basalt. Our results demonstrate that four marked lithospheric thinning events occurred during the Paleoarchean, early Paleoproterozoic, Neoproterozoic, and Phanerozoic with intermediate thickening scenarios.

2015年1月1日 · The oceanic lithosphere is composed of the lithospheric mantle and the oceanic crust with mainly gabbroic and basaltic rocks formed at the oceanic spreading centers. The thickness of the oceanic lithosphere increases with increasing distance to the spreading center because new lithospheric material is continuously added at the base of the ...

1997年11月1日 · The main objective was to improve understanding of the origin and evolution of the Earth`s lithosphere by studying selected processes, such as deformation and magmatic intrusion during crustal extension, formation and extraction of mantle melts, fluid transport of heat and mass, and surface processes that respond to deep-seated events.

There are a variety of lithospheric processes that form and transform environments. These include: Erosion: Erosion is the wearing away of earth by wind, water or ice. Moving water and rain carry...

2000年12月1日 · Numerical modeling yielded robust and accurate predictions of these processes. This work is important fundamental science, and applies to mitigation of volcanic and earthquake hazards, Test Ban Treaties, nuclear waste storage, environmental remediation, and hydrothermal energy. | OSTI.GOV
