The tectonic evolutionary history between the Xing’an Block (XB) and Songnen Block (SB) in the eastern Central Asia Orogenic Belt (CAOB) has been hotly debated. In this study, we present a series of new data to provide a better constraint on the magmatic process during plate subduction and its implications for the regional tectonic evolution of XB and SB, even the CAOB. The whole-rock geochemistry and zircon U-Pb chronology of syenogranite in the Chaihe area of the Great Xing’an Range have been carried out.

Apatite fission track (AFT) thermochronology is applied to the Horozköy granitoid, which outcrops within the Bolkar Mountains (south-central Turkey). The region comprises the Niğde Massif to the north, the Inner Tauride Suture Zone, and the Central Taurides to the south. The Niğde Massif and the Central Taurides collided during the Eocene following north-dipping subduction of the Inner Tauride Ocean beneath the Niğde Massif. The Ulukışla Basin formed above this suture zone.

In this article, the petrological processes of the clinopyroxenite dykes and host peridotites occurring in Ulaş District (Sivas, mid-Anatolia, Turkey) are discussed. The new geochemical data from major minerals in the clinopyroxenite dykes and host harzburgites revealed differences to the supra-subduction zone (SSZ)-type pyroxenites and peridotites.

(BQ) Tài liệu Earth science: Ring of Fire includes about what is the Ring of Fire? How is a subduction zone formed? What part of the 1906 earthquake in San Francisco caused the most damage? Why? According to the theory of continental drift, the continent Pangaea gradually split into the seven continents on Earth today. Describe the evidence that supports this theory.
