This research can be regarded as a pilot study at El Chichón Volcano to assess whether REE distributions can be used as routinely geochemical tracers in the Crater Lake geothermal system. Eighteen lake water samples were collected during 3 field…

Petrography, major (including four trace elements), stable isotopes (carbon and oxygen), and 87Sr/86Sr geochemistry of limestones of the Shahabad Formation, Bhima basin, Karnataka, southern India are reported. These limestones show a narrow range of δ13C (1.34-1.96)…

Low grade metasedimentary rocks in the western Acatlán complex (Olinalá area) of southern Mexico occur in two units termed here the Progreso and Zumpango units of Lower and middle Carboniferous ages, respectively. The Zumpango Unit is dominated by phyllite and…

Provenance and tectonic setting ofthe Upper Devonian sandstones in NW Iran have been interpreted on the basis of petrography and trace-element analysis of samples from two different stratigraphic sections. Modal analysis data of 27 samples with medium sand size and…

The Cretaceous Nuevo Rosarito plutonic suite is located in the southern part of the Peninsular Ranges batholith (~28.7 °N). It is hosted by a suite of Jurassicgranitoidrocks datedat 151.6Ma (U-Pb single zircon ages) and by Late Jurassic - Early Cretaceous…

This paper presents a synthesis of the applications of evaporite mineralogy and the relationship between major elements for the palaeoclimatological research of arid regions, with examples from Playa Oum el Krialate in Tunisia, Wadi Natron in Egypt, East African Rift…

The Rabanpalli Formation exhibits two types of shales, viz. grey and calcareous shales. These shales (grey and calcareous) have been analysed for major, trace, and rare earth elements to find out their source rocks characteristics and paleo-oxygenation conditions. The grey…

An integrated petrographic and geochemical study of the Ahwaz Sandstone Member ofOligocene-Miocene age, Asmari Formation in Zagros, southwest Iran, was carried out to infer their provenance and tectonic setting. This study is based on the analysis of core samples from…

A suite of mafic dikes intrudes polydeformed, greenschist facies, metapsammites and metapelites of the Salada unit in the eastern part of the Acatlán Complex, southern Mexico. The age of the dikes is constrained by the youngest detrital zircon in the…

Petrographic, major, trace, and rare-earth element geochemistry of sands from three beaches of México (Cazones, Acapulco, and Bahía Kino) were studied to determine their provenance. The textural study reveals that the proportion of quartz is higher in Bahía Kino (~48-83…
