In this research, petrographic and geochemical (major and trace elements) characteristics of siliciclastic rocks of the Mozduran Formation in the eastern Kopet-Dagh Basin have been carried out in order to reveal their provenance such as source area paleoweathering, parent rock composition and tectonic setting. Mozduran Formation is mainly composed of limestone and dolomite, with minor amounts o...

the nasirabad manganese deposit is located 5 km south of nasirabad, 8 km sw of neyriz in the fars province. structurally, the area is placed in the southeastern part of zagros thrust belt. in this area, the manganese mineralization occurred as ore layers and nodules, interlayered with pichakun radiolarite chert deposits. in this study, mineralogy and geochemistry of uranium, thorium and lead is...

introduction soil salinity and expansion tts it, in the arid and semi-arid areas is including environmental issues that in recent years attention has been due to population growth and the need to utilizeland. in order to human was tried that using of different techniques determined salinity area between remote sensing data in recent years have provided relatively accurate results as a source of...

Quantitative subsidence analysis of 26 wells in the Lusitanian basin provides new constraints on the western Iberian Mesozoic passive margin development. Backstripped tectonic subsidence curves show a three-fold subdivision of vertical motions from Late Triassic onward. Continental rifting was initiated during the Late Triassic and Early Jurassic. From Middle Jurassic onward a distinct differen...

evaluation of the geochemistry and hydrochemical quality of bam salt dome located in southern iran, was conducted in this study. two composite samples from salt units were collected and analysed by xrd and xrf to determine their mineral and elemental compositions. water samples were also collected from the only spring in the area and analysed for major anions, cations and some toxic elements. t...

Recem Ocean Drilling Program sampling of the Ctte d'Ivoire-Ghana margin of West Africa provides for the first time the opportunity to study the development of a marginal ridge that formed along a sheared passive margin adjacent to the continent-ocean transition after the end of intmcontinemal wrenching. We model its evolution using a two dimensional flexural backstripping technique. The model i...

This work aims to present the Les Avellanes diapir as a field analog inquire how origin, advance, and emplacement of an allochthonous salt body in continental settings influence local sedimentation terms facies distribution, sediment provenance, stratigraphic relationships. At frontal part South-Central Pyrenean fold-and-thrust belt (Spain), is outcropping structure made Triassic evaporites, lu...
