Whole rock geochemistry tectonic setting
Best insight from top research papers
Whole rock geochemistry can provide insights into the tectonic setting of a region. The geochemical analyses of the Upper Shihezi and Shiqianfeng sandstones in the Ordos Basin suggest different tectonic settings for these formations. The Upper Shihezi sandstones were most likely derived from a mixed felsic-mafic source, indicating a transitional setting from passive continental margin to active continental margin . On the other hand, the sandstones of the Shiqianfeng Formation were mainly derived from a felsic source, suggesting an active continental margin setting . The Raobazhai ultramafic complex in the Dabie Mountains also provides insights into the tectonic setting. The presence of water-bearing minerals and the enrichment of Sr, Ba, and U, along with the depletion of Nb, Zr, and Hf, indicate strong metasomatism of boninitic melting/fluid in the fore-arc domain, suggesting a fore-arc boninitic melting/fluid transformation event . The geochemical characteristics of the sandstones from the Barail and Surma Groups in the Mizoram Foreland Basin suggest that they were sourced from different felsic magmatic lithounits of the Himalaya and were deposited in an active continental margin . The Lisar granite in Kuzey Iran is also indicative of a tectonic setting. It represents the magmatism following the collision of the Paleotethys Ocean, suggesting a post-collisional magmatism in the region .

What is the importance to know the structural tectonic setting on an orogen?5 answersUnderstanding the structural tectonic setting of an orogen is crucial for deciphering the complex geological processes that shape mountain belts. By analyzing convergent orogens, lateral heterogeneities, deformation styles, and lithological variations can be identified, shedding light on the evolution of orogenic belts and seismic activity. Orogenic gold deposits, typically formed in subduction-related settings, provide insights into fluid pathways, depositional mechanisms, and structural controls within orogens. High-pressure metamorphic rocks in orogens reveal details about burial, exhumation processes, and tectonic evolution, aiding in understanding global geodynamics and plate tectonic processes. The Grenville Province exemplifies the challenges in interpreting orogenic infrastructure due to high-grade metamorphism and polyphase reworking, emphasizing the importance of recognizing protoliths and original relationships for accurate tectonic interpretations. By integrating data from various orogenic settings, a comprehensive understanding of the structural tectonic setting in an orogen can provide valuable insights into geological history and processes.
Plate tectonics: What, where, why, and when?4 answersPlate tectonics is a theory that describes the horizontal movement of Earth's lithosphere, which is divided into multiple plates that float on the asthenosphere. These plates can move apart, converge, or slide past each other, leading to various geological processes such as mountain building, ocean opening and closing, and the formation of volcanoes and earthquakes. Plate tectonics is driven by the negative buoyancy of the lithosphere in subduction zones, where denser oceanic plates sink beneath less dense plates or continents. The theory of plate tectonics is a self-organizing complex system, controlled by dissipation in the bending lithosphere and viscous mantle. The onset and operation of plate tectonics are associated with plate divergent-convergent coupling systems, which are responsible for the creation and maintenance of plate boundaries. The geologic record provides evidence for plate tectonics, including ophiolites, metamorphic belts, transform faults, and geochemical indicators in igneous rocks. Plate tectonics has been a fundamental process in shaping Earth's surface and has been operating since at least the Neoproterozoic era.
What are the tectonic provinces of South America?3 answersSouth America is divided into several tectonic provinces. In the Neoproterozoic Brasiliano fold belts, tectonostratigraphic terranes have been recognized in the Tocantins, Mantiqueira, and Borborema provinces. The stress field in northern South America indicates two geotectonic provinces: one in the mountain regions from the Colombia/Ecuador border to the Cordillera de la Costa, and another from the Colombian Llanos to the Guayana Shield. The MAGSAT scalar magnetic anomaly data reveals different geologic correlations in South America, with the continent being divided into Precambrian shields and cratons, Phanerozoic basins and grabens, the Patagonian Platform, and the Andean Fold Belt and Caribbean Mountain System. The tectonic setting of Upper Jurassic to Eocene alkaline rocks in Brazil, Bolivia, Paraguay, and Uruguay is grouped into twelve alkaline provinces. The broadscale distribution of ore deposit types in South America also suggests the presence of major geotectonic features.
What are the tectonic provinces of South America, including orogenic belts and cratons?4 answersSouth America consists of several tectonic provinces, including orogenic belts and cratons. The orogenic belts mentioned in the abstracts are the Araguaia Belt, Paraguay Belt, Brasilia Belt, Aracuai Belt, Ribeira Belt, Dom Feliciano Belt, and Sergipano Belt. The cratons mentioned are the Amazon craton, Sao Francisco Craton, Rio Tebicuary craton, Southern Parana craton, and Rio de la Plata Craton. These cratons are characterized by their cold and buoyant behavior and are surrounded by mobile belts formed during the Neoproterozoic. The tectonic provinces mentioned in the abstracts are the Tocantins, Mantiqueira, Borborema, and Chaco-Parana provinces. These provinces are associated with different terranes and have distinct lithospheric structures and electrical properties. Overall, South America exhibits a complex collage network of tectonic provinces, orogenic belts, and cratons, which have played a significant role in the continent's geodynamic and tectonic evolution.
What are initial conditions for plate tectonics?5 answersThe initial conditions for plate tectonics on Earth are influenced by factors such as the rotational velocity and revolutionary periodicity of the planet around the Sun. These initial orbital conditions are affected by processes like core segregation and Moon formation, which have led to the initiation and persistence of plate tectonics. Additionally, the change in orbital conditions could have resulted in a near-linear trend, where the rotational periodicity of the planet approaches the time taken for the planet to travel one degree in its orbit around the Sun. This optimal condition for rotational and revolutionary periodicities is considered essential for the development of plate tectonics on Earth. These findings have implications for the possibility of plate tectonics and life on extrasolar planets and potentially habitable solar planetary bodies.
How tectonic processes connect rock and cycle?5 answersTectonic processes connect rock and cycle by reorganizing rock processes into a tectonic framework. This framework replaces descriptive rock classifications with tectonic rock classifications that focus on rocks characteristic of major tectonic regimes. The tectonic rock cycle begins with igneous-fractionation processes at divergent and convergent plate boundaries, generating major igneous rocks. Subduction-generated volcanic arcs undergo weathering and erosion, producing lithic-rich sediments. Weathering and erosion of the batholithic core of the volcanic arc generate arkosic to quartzitic sediments, resulting in the formation of quartz/feldspar/lithic (QFL) end-member clastic sediments. Carbonates are associated with quartz. These processes spatially separate the different types of clastic sediments in the rock cycle.In an integrated systems framework, tectonic processes are interconnected with other earth systems through feedback loops. Plate tectonics and rock classifications are integrated within an earth systems viewpoint, where supercontinent cycles are viewed in both spatial and temporal dimensions. The classification of rock types is dependent on the tectonic and depositional environment in which they were formed. Visualizations, such as animations and images, can be used to investigate supercontinent cycles and equate rock genesis with tectonic and environmental settings. These visualizations assume a primary role in instances where spatial and temporal relationships are of interest. Teaching a systems-based understanding of the Earth and evolving tectonic and rock cycles provides students with holistic foundations for evaluating their living environment.Igneous rocks are formed by the solidification and cooling of magma in volcanic areas, while sedimentary rocks are formed by the accumulation of sediments in tectonic basins and topographical sinks. Metamorphic rocks are formed by the application of temperature and pressure on pre-existing rocks. Each of these rock types can be further classified based on chemistry, formation process, and environment. The distributions of these rock types are critical in regional mapping of natural resources. Igneous rocks are indicators of volcanism and associated with geothermal resources and hydrothermal deposits. Sedimentary rocks, especially organic sediments, are good source rocks and proxies for environmental reconstruction. Metamorphic environments are associated with gemstones and alteration minerals.The cyclic view of geology gained strength in Europe as a neo-Huttonian view when radiometric dating revealed the true extent of geologic time. This view explained the salt content of the ocean and the sodium fixed in metamorphism of sediments to paragneiss. In North America, there was an independent movement to claim the rightful place of sediments and cyclic processes in geologic theory. It was acknowledged that the cyclic and secular views of the Earth are complementary and that geologic materials are recycled on varying time scales against a background of slow, secular evolution of the Earth.The rock cycle can be taught using specially designed cards that allow students to play games and learn about the different rock types and the processes by which one rock type is changed into another. The deck of cards contains the titles of various rock types, along with the names and pictures of specific rocks that fit into each type. The cards are color-coded to aid in differentiation between types, and the processes of rock transformation are reinforced through colored squares on the cards. This approach provides an interactive and engaging way for students to understand the rock cycle.
