The geology of the Aracruz pluton (Espírito Santo, Brazil), a Cambrian post-orogenic intrusion in the aftermath of Gondwana amalgamation

Journal of Maps
We present the first geological map of the Aracruz pluton (Espírito Santo, Brazil), which belongs to the late Cambrian post-orogenic suite that intruded the Nova Venécia metapelites and Ediacaran syn-orogenic S-type granites of the Araçuaí belt.

The Wiley Glacier complex, Antarctic Peninsula: pluton growth by pulsing of granitoid magmas

, 1997
Early Cretaceous gabbro, quartz-diorite-granodiorite, and tonalite-granodiorite plutons of the Wiley Glacier complex, in the Antarctic Peninsula magmatic arc, were emplaced in a zone of syn-magmatic extensional shearing.

Изменение строения поверхности гетерогенного тела (диорита) при трении

, 2018
Raman, infrared, and photoluminescent spectroscopy has been used to study changes in the surface structure of quartz diorite caused by friction. Before friction, the diorite surface layer has contained mainly quartz and feldspar crystals. After friction,
