Apatite minerals of I-type Zouzan granitoids and typical garnet-bearing S-type granites have been analyzed by electron microprobe to define trace element concentrations and compare them in different granites. Zouzan granites are composed of apatites with lower Fe, Mn, Na and HREE and higher REE and ∑REE relative to S-type ones. Trace elements abundances of apatite often vary with some parameter...

Sediment from Lake Towuti has been extensively studied to reconstruct past climate and environmental changes. One of the remaining questions is source magnesium (Mg) calcium (Ca) in northern part Towuti. In this study, high Mg Ca content examined by analysing surface sediment Lampenisu River (LR) Mahalona (MR) that merge before entering Twelve sediments MR, LR, confluence two rivers (LMR) were ...

The definition of pre-Messinian source rocks in the eastern Mediterranean is paramount importance for hydrocarbon exploration because ability salt to act as a high-quality seal rock. This research evaluates organic geochemical features Upper Miocene (Tortonian—Messinian) sedimentary succession onshore Crete Island, Greece. study employs original (Messinian, Agios Myron Fm) and published (Torton...

A number of hydrocarbon discoveries have been made recently in the Flemish Pass Basin and Central Ridge, offshore Newfoundland, Canada, but there is only limited geological information available. The primary goal this study was to determine sedimentary provenance paleodrainage patterns mudstones sandstones from Upper Jurassic Rankin Formation, including Lower Kimmeridgian Source Rock (organic-r...

rock-eval pyrolysis and oxidation are the most widely used methods by exploration companies for identifying and evaluating potential source rocks in sedimentary basins. in this article, these methods and the parameters resulted from their application are first  explained.  then,  based on screened data resulted from analyzing 499 outcrop samples by using rock-eval pyrolysis and oxidation method...

The Etive igneous complex has intruded into Dalradian and Moine meta-sedimentary rocks in Devonian. Main rock types of the complex are granodiorite, monzodiorite, monzogranite, granite and diorite. Geochemical studies show that the magmas were of high K calc-alkaline, I-type and metaluminous nature. Application of discriminant diagrams to the Etive rocks indicates a possible within-plate tecton...

miocene silisiclastic sediments in binalood zone consist of three lithofacies group including gravelly (gmm, gcm, gci, gh, gt, gp), sandy (st, sm, sh, sp, ss, sl) and muddy (fm, fl). gravelly lithofacies are generally massive and mainly consist of volcanic and sedimentary lithic in different size. sandy lithofacies are composed of litharenite and feldespathic volcanicarenite and rock fragments ...
