Variability of orogenic magmatism during Mediterranean-style continental collisions: A numerical modelling approach [PDF]
Gondwana Research, 2018 The relationship between magma generation and the tectonic evolution of orogens during subduction and subsequent collision requires self-consistent numerical modelling approaches predicting volumes and compositions of the produced magmatic rocks. Here, we use a 2D magmatic-thermomechanical numerical modelling procedure to analyse rapid subduction of a ...

Magmatism of the Kenya Rift Valley : a review. [PDF]
, 2003 Tertiary–Recent magmatism in the Kenya Rift Valley was initiated c. 35 Ma, in the northern part of Kenya. Initiation of magmatism then migrated southwards, reaching northern Tanzania by 5–8 Ma.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Integrating multiple detrital mineral systems provides a powerful framework for reconstructing source‐region tectonothermal evolution because different minerals record complementary aspects of magmatic and metamorphic processes. Glacial diamictites are particularly valuable for this approach because extensive glacial erosion can sample broad ...

Post-orogenic Mesozoic basins and magmatism [PDF]
, 2013 This chapter describes the later Mesozoic history of Queensland, when the broad epicratonic basins that underlie most of the state west of the Great Dividing Range received the greater part of their sediment infill after ~210 Ma(middle Norian). The final

Geochemical and boron isotopic compositions of tourmalines from selected gold-mineralised and barren rocks in SW Finland [PDF]
Bulletin of the Geological Society of Finland, 2010 Tourmaline-bearing rocks and a number of gold occurrences coexist in southwestern Finland, in a region where extensive magmatism and hydrothermal systems occurred during the Svecofennian orogeny, 1.9-1.8 Ga ago.

Apatite as a Proxy for Reconstructing Magma Mixing Histories in Granitoids
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Apatite is a common accessory mineral in granites and mafic microgranular enclaves (MMEs), and its textural and compositional characteristics can record dynamic magmatic evolution processes. Apatites from the Early Cretaceous Sanguliu granite and its MMEs in the Liaodong Peninsula exhibit pronounced compositional heterogeneities. In this study,

Petrogenesis of early Paleozoic I-type granitoids in the Longshoushan and implications for the tectonic affinity and evolution of the southwestern Alxa Block [PDF]
Solid EarthIn the Paleozoic, the Alxa Block was situated between the Central Asian Orogenic Belt and the North Qilian Orogenic Belt, and it experienced intense magmatic activity. Thus, the Alxa Block is an important area for understanding the tectonic framework and

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract The nature of mantle sections exhumed at magma‐poor rifted margins remains poorly constrained, largely because direct sampling of mantle in modern passive margins is exceptionally rare. The Iberia–Newfoundland system is unique in providing drilled mantle rocks on both conjugate margins, offering an unprecedented glimpse into mantle ...
