Middle Miocene forearc alkaline magmatism in Amami-Oshima Island, central Ryukyu Arc: implications for paleoreconstruction of Shikoku Basin [PDF]
Earth, Planets and Space, 2023 During the middle Miocene, forearc alkaline magmatism occurred in the Outer Zone of Southwest Japan and the northern Ryukyu Arc, resulting in the formation of forearc alkaline basaltic rocks with ocean island basalt (OIB)-like chemical signatures.

Marcasite at the Permian‐Triassic Transition
Geophysical Monograph Series, Page 377-399., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Uma síntese sobre o magmatismo alcalino do Paraguai Oriental [PDF]
Brazilian Journal of Geology, 2013 Alkaline magmatism occurs in six distinct areas of Paraguay and forms bodies of variable size, shape, composition and age. The oldest rocks are found in the north and correspond to the Permo-Triassic Alto Paraguay Province (241 Ma). Four Early Cretaceous

Petrographic and geochemical characteristics of olivine basalts from east of Nehbandan and Chahchocho (Sistan suture zone, eastern Iran) [PDF]
پترولوژی, 2020 Olivine basalts from east of Nehbandan and Chahchocho regions belong to sodic alkaline and transitional magma series. Compared to alkaline olivine basalts (AOB), the transitional olivine basalts (TOB) have higher MgO, SiO2, Ni, Cr, Ba, Th, Pb, and U, and
