Ryugu reference project: Recommendations from the measurement definition team
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 819-848, May 2026.Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,

Tectonics, Volume 45, Issue 4, April 2026.Abstract The Northern Aegean region preserves a complex deformation pattern shaped by Miocene extension driven by retreat of the Hellenic subduction system, later overprinted by Plio–Pleistocene transtension linked to the westward propagation of the North Anatolian Fault (NAF). Although numerous structural, geophysical and geochronological studies have

Early Tertiary epithermal gold mineralization, Bahcecik prospect, northeastern Turkey
, 2000 The Bahcecik prospect is located in the eastern Pontide tectonic province of the eastern Black Sea region of Turkey. It is one of the first low sulfidation epithermal systems to be described from this area of Turkey.

Early Holocene jökulhlaup chronology and deglaciation dynamics in central Iceland
Boreas, Volume 55, Issue 2, Page 340-355, April 2026.Glacial lake outburst floods (jökulhlaups) have occurred throughout the Quaternary in glaciated regions worldwide. Reconstructing flood chronology yields insight into deglaciation processes, environmental change and the role of extreme events in landscape evolution.

Giant Porphyry Copper Deposits Caused by a Slab Jamming in the Mantle Transition Zone
Terra Nova, Volume 38, Issue 2, Page 106-115, April 2026.ABSTRACT Two giant porphyry copper deposits in the Southern Central Andes formed during the Miocene–Pliocene transition when a bend in the subducting Juan de Fernández hotspot chain jammed in the mantle transition zone, causing mega‐scale slab‐kinking. This geometry implies mechanical resistance that caused East–West compression and eventually a thrust‐

Pb-Zn and minor U mineralization at Tyndrum, Scotland. [PDF]
, 1985 This mineralization occurs as veins and vein breccias in fractures associated with the Tyndrum-Glen Fyne fault. Quartz, galena and sphalerite, with minor chalcopyrite and baryte, are accompanied by small inclusions (in the galena-rich veins) of ...
