In recent years, considerable progress has been made on the study of Mo isotopes in high-temperature geological processes. However, it is still controversial whether isotope fractionation occurs during magmatic differentiation. Here we reassess effect magma differentiation using published data conjunction with our new analysis well-characterized I-type granitoids and their enclosed mafic enclav...
The presented studies are aimed to determine the formation patterns of gold-rare metal mineralization within one most inaccessible Arctic islands Russian Federation, Bolshevik Island Severnaya Zemlya archipela-go. relevance work is determined by high probability discovering a significant in terms reserves deposit, which proved many researchers on example known large deposits be typical feature ...
To gain insights on long-term social-ecological resilience, we examined adaptive responses of small-scale societies to dryland-related hazards in different regions and chronological periods, spanning from the mid-Holocene to the present. Based on evidence from Africa (Sahara and Sahel), Asia (south margin of the Thar desert), and Europe (South Spain), we discuss key traits and coping practices ...
The area of study is located 120 Km north-east of Shahrood city. In terms of structure and geological classification, this area is located in the northern part of central Iran zone. Granitoids of Troud ranging from monzonite to granite. The main minerals of granitoids are quartz, plagioclase, and orthose. The accessory minerals are biotite, hornblende, sphene, and opaque minerals. Various textu...
The study area is located in North-East of Lut block, and in Basiran Geological Quadrangle Map (1:100000).Tertiary intrusive-subvolcanic rocks intruded Paleocene limestone and formed skarn and Iron mineralization. Petographic studies show that rocks are Hbl-diorite porphyry, Hbl-qtz- diorite porphyry, Px- diorite porphyry, Hbl-px- diorite porphyry, Hbl-diorite and Bt-diorite. These rocks are s...
Trace elements distribution in granitic quartz is highly sensitive to differentiation processes. Abundance of Ti, Ge, Al and Li in primary quartz of Naqadeh granitoids have been studied by Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). Trace elements ratio in quartz exhibits completely different trends in two different Naqadeh granitoid units (more mafic granitoids (MM...
India has been one of the largest producers oilseeds in world. Correspondingly, oilseed sector occupies an important position agricultural economy country. Oilseeds, especially edible oilseeds, have integral part cropping system till beginning monoculture triggered by implementation a new agriculture strategy since 1960s. This paper evaluates pattern diversity Thar Desert Rajasthan at district ...
Oligo-Miocene Bagh-e-Khoshk granitoid stock is intruded into the Eocene volcanic rocks in the southeastern part of the Urumieh-Dukhtar Magmatic assemblage in Iran. The granitoids are mainly consisting of diorite, quartz diorite and granodioritic rock types. They are metaluminous to slightly peraluminous, medium to high K calc-alkaline, with SiO2 ranging from 50.2 to 66 wt.%. The majo...
