Kinematic evidence for cordierite porphyroblast growth in a contact aureole during progressive deformation; Shah-Kuh granitoid, NE Lut Block, Iran
The Shah-Kuh granitoid has intruded in the Triassic–Jurassic, pelitic and psammitic low-grade metamorphic rocks of the NE LutBlock, in Central Iran. Cordierite porphyroblasts are common in the southern pelitic sediments, but are rare in the northern psammiticrocks, in the contact aureole. Deformation fabrics in the contact aureole are well-preserved within the cordierite porphyroblasts. Therela...
متن کاملOrigin and evolution of ore-forming fluids in the magnetite±apatite Lake Siah deposit (Bafq): Evidence of fluid inclusions and oxygen stable isotope
The Lake Siah magnetite ± apatite deposit is situated in the northeastern of Bafq and Central Iran tectonic zone. The host rock of deposit is composed from lower Cambrian volcano-sedimentary sequence that has exposed as caldera complex. The iron mineralization is as massive ore and includes magnetite and hematite which form with apatite, quartz and calcite gangue minerals. Based on fluid inclus...
متن کاملfluid inclusion and sulfur stable isotope evidence for the origin of the ahangran pb-ag deposit
introduction the ahangaran pb-ag deposit is located in the hamedan province, west iran, 25 km southeast of the city of malayer . . the deposit lies in the strongly folded sanandaj-sirjan tectonic zone, in which the ore bodies occur as thin lenses and layers. the host rocks of the deposit are early cretaceous carbonates and sandstones that are unconformably underlain by jurassic rocks. ore miner...
متن کاملA review of research dealing with isotope hydrology in Iran and the first Iranian meteoric water line
For more than half a century isotopes have been employed as a powerful tool in studying various aspects of water resources in a largenumber of countries. However, in developing countries like Iran the application of such techniques is in its infancy. The first research inIran was carried out in 1975 to identify the source of saline groundwaters in south Iran, and the first national conference o...
متن کاملOxygen isotope evidence for the origin of HEDs and Angrites
Introduction: HEDs and angrites represent distinct suites of mafic igneous rocks formed early in the history of the Solar System [1]. Despite their mineralogical and chemical differences both groups have similar O-isotope compositions [2]. To examine the origin of HEDS and angrites we have undertaken a high-precision study of their O-isotope systematics. Experimental Techniques: Oxygen isotope ...
