Geology and petrology of the Salto do Céu Suite: tectonic and stratigraphic implications on the SW Amazonian Craton

Brazilian Journal of Geology
: The basic rocks of the Salto do Céu Suite outcrop as sills and flows in the southwestern Amazon Craton, Rondonian-San Ignacio Province, with an age of about 1.44 Ga. Sills are 2 to 30 m thick being hosted by pelites of the Aguapei Group.

Modelling diverse processes in the petrogenesis of a composite batholith: the Central Bohemian Pluton, Central European Hercynides

, 2000
The multiple intrusions making up the Central Bohemian Pluton in the Central European Hercynides have petrographic and geochemical features consistent with the presence of four main granitoid suites.

Petrogenesis of Very‐Low‐Ti Basalts Returned by Chang'e‐6 From the Lunar Farside

Geophysical Research Letters
Lunar volcanism provides critical insights into the Moon's thermochemical evolution. We present petrological and geochemical analyses of six very‐low‐Ti (VLT) basalt fragments from Chang'e‐6 (CE6) samples. These basalts yield a Pb‐Pb age of around 2.9 Ga,

Geochemistry and petrogenesis of forearc peridotites, ODP Leg 125 [PDF]

, 1993
ODP Leg 125 recovered peridotites from Conical Seamount in the Mariana forearc and Torishima Forearc Seamount in the Izu-Bonin forearc. The peridotites recovered comprise about 95% harzburgites and about 5% dunites, which are variably serpentinised ...
