Tin in granitic melts: The role of melting temperature and protolith composition
Lithos, 2018 Abstract Granite bound tin mineralization typically is seen as the result of extreme magmatic fractionation and late exsolution of magmatic fluids. Mineralization, however, also could be obtained at considerably less fractionation if initial melts already had enhanced Sn contents.

Geological evidence for a 2.6-Ga strewn field of impact spherules in the Hamersley Basin of Western Australia [PDF]
Sand-sized spherules up to 1.7 mm across with spherulitic, vesicular, and other crystalline textures that consist mainly of K-feldspar help define a unique horizon in the well-preserved 2.6-Ga Wittenoom Formation in the Hamersley Basin of Western ...
