The Khaviz oil field located in Dezful embayment is one of Iran’s southwest oil fields. In this study, a total of 28 cutting samples from Kazhdumi formation (well No. KZ1, Khaviz oil field) were subject to geochemical investigation using Rock-Eval pyrolysis for the first time. The results of pyrolysis indicated that Kazhdumi source rock has significant hydrocarbon production potentiality and al...

Geothermal resources are currently obtained from areas within volcanic arcs, such as the Pertamina Ulu Belu and Supreme Energy Rajabasa Fields. However, this understanding may change in future, Quaternary Sukadana Basalt Province (SBP), located back arc, is believed to have potential a future geothermal energy resource. This research aims explore various factors that contribute high heat flow S...

The rift-related magmas of the Proterozoic Gardar Igneous Province were emplaced across the contact between the South Greenland Archaean craton and the Palaeoproterozoic Ketilidian mobile belt. It has been suggested that the geochemistry of Gardar intrusive rocks in the two areas varies across the craton margin and that this reflects a lithospheric control. However, comparison of the geochemica...

The Sirt Basin important oil producing area in Libya is one of the richest regions terms hydrocarbon resources. Exploration studies this have shown that oils are mixtures several charges and may be from different source rocks particularly upper Cretaceous sediments study based on organic geochemistry petrographic analysis carried out 179 cutting samples collected four wells. From Cenomanian to ...

The mineralogy and geochemistry of the bulk rock and clay fraction of sediments deposited at the CretaceousTertiary transition and in the KTB layer have been investigated by various methods in two sections from the Betic Cordilleras (Agost, Caravaca) and five sections from the Basque-Cantabrian Basin (Monte Urko, Sopelana, Zumaya, Hendaye, Biarritz). Active terrigenous supply prevailed in both ...

[1] We report zircon oxygen isotope ratios and reconnaissance Ti-in-zircon concentrations, guided by cathodoluminescence image studies, for detrital zircons up to 4.34 Ga from the Narryer Gneiss Complex of Western Australia. Zircon oxygen isotope results bolster the view that some Hadean (>3.85 Ga) zircon source melts were enriched in heavy oxygen, a sensitive proxy for melt contamination by se...

The transition from 41to 100-kyr glacial cycles and concomitant increase in global ice volume ~1 Ma remain an enigmatic feature of late Cenozoic climate. Here, we examine the petrology, mineralogy, and geochemistry of the silicate fraction of tills spanning the past 2 Ma from the north-central United States to evaluate the hypothesis that this so-called middle Pleistocene transition (MPT) occur...

The geochemistry of river sediments is routinely used to obtain information about geologic and environmental processes occurring upstream. For example, downstream samples are constrain chemical weathering physical erosion rates upstream, as well the locations mineral deposits or contaminant sources. Previous work has shown that, by assuming conservative mixing, can be reliably predicted given a...

The major element composition of volcanic rocks carries important information about the source and differentiation processes affecting magma, physical properties that allow it to erupt, its eruptive style. Although global rock geochemical databases exist, these are not linked eruption history which hampers our understanding relationship between magma dynamics. Here, we integrate two databases, ...
