The study area is located in Tertiary plutonic belt of Lut Block.  Tertiary intrusive injection in Cretaceous limestone caused the formation of skarn in this region. Injection intrusive changes the texture and mineralogy of limestone and skarn or marble formed. A lens-shaped iron mineralization mainly occurred in the border of intrusions and calcareous unit. Petrological studies show that the w...

Lower Paleozoic metabasites of south Chah Palang are located in north of the Yazd block in Central Iran with limited distribution and are associated with Doshakh metamorphites. Metabasites divided in to two portions: metavolcanics, and metagabbro, amphibolite and metadiabase masses. Metavolcanic with basaltic composition are presented by foliation and vesicles filled by calcite. Amphibole, plag...

Recognition of growth pattern and folding mechanism in the fold-thrust belts with hydrocarbon resources is important in exploration and development planning of oilfields. As the processes of tectonics, erosion, and geomorphology impact on each other, therefore, the investigation of a process, one can obtain information about the other process. In this research the tectonic process of transverse...

The results of this study indicated that the synoptic patterns that lead to heavy rainfall in 22 March 1996, 24 mar 1995 and 17 November 1994 in the northern portion of FARS province includes: the low pressure that located in eastern part of Mediterranean and Black sea and southern part of Caspian Sea that created by trough that located at the middle level of atmosphere. In addition to this low...

There are different methods to investigate the effects of climatic fluctuations on the biota, two of which, molecular phylogeography and SDM, are the most useful tools to trace the past climate induced modifications on species’ geographic distributions. In this study, seven samples were collected from the species distribution range in Iran for the purpose of measuring the genetic variation with...

.  Introduction Old trees are important and key elements of forest sites and are of great value in terms of forest management, reforestation, silviculture and ecology. Although old trees constitute a small percentage of forest trees, they account for a large share of forest carbon reserve and play a vital role in carbon storage. Understanding the how geographical and site distribution of thes...

Background and Objectives:Anzali Wetland is one of the most important aquatic ecosystems of Iran which is located in south-west of the Caspian sea. This Wetland provides a suitable and non-market price habitat for valuable fish and aquatic animals which have an important role in the life cycle of this ecosystem. This study reports the results of some heavy metals contamination monitoring in sup...
