Anomalously cool clumped isotope temperatures in tropical lagoon carbonates
The Depositional Record, EarlyView.Carbonate clumped isotopes were used to reconstruct paleoclimate from lagoon sediments in the central tropical Pacific. Results were anomalously cool compared to modern measurements and other paleoclimate records. This study highlights the important of understanding carbonate facies and depositional environments in interpreting clumped isotope results.

Petrology of hydrothermal metasomatism of intra-ore dolerite dikes of mesothermal gold deposits
Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 There is a necessity of working up the geology-genetic theory of hydrothermal gold deposit formation instead of the four hypotheses excepting one another: granitogene, basaltogene, metamorphogene, polygene.

Mineral chemistry and geothermobarometry of gabbroic dykes of the Garmab Ophiolite sequence (Northeast of Kamyaran) [PDF]
پترولوژی, 2018 The Garmab ophiolite complex, a part of the Ophiolite-Radiolithic zone of Kermanshah, is located in the northeast of Kamyaran. In view of the Iranian geo-structural zones, this complex is situated between the Sanandaj-Sirjan Zone and the Zagros thrust ...

The Depositional Record, EarlyView.The lower Eocene Alveolina Limestone records the global early Eocene transgression, but is equally affected by tectonic movements of the Montsec active thrust located in its hangingwall. Tectonic movements and the early Eocene transgression facilitated a detrital provenance shift in the southern Pyrenean foreland from a southern provenance in the ...

Mesozoic-Cenozoic mafic magmatism in Sanandaj-Sirjan Zone, Zagros Orogen (Western Iran): geochemical and isotopic inferences from Middle Jurassic and Late Eocene gabbros [PDF]
, 2017 One of the consequences of Neo-Tethys ocean subduction beneath the Central Iranian Micro-continent (CIMC) is the development of rare gabbroic intrusions in the Malayer-Boroujerd Plutonic Complex (MBPC) located in the Sanandaj-Sirjan Zone (SaSZ) of the ...
