The Kamar-Mehdi fluorite deposit is located 100 km southwest of Tabas in Tabas Block, Central Iran. There are five stratabound orebodies in the area exposing in carbonate rocks of Shotori Formation. The oldest unit is Shotori Formation dolomite of Triassic age that is emplaced in the core of Kamar-Mehdi Anticline. Folding direction in the area is N-S and normal faults with W-E direction have ca...
In this research, paleoecology of Baghmashah Formation in Rizu section based on calcareous nannoplanktons has been investigated. Baghmashah Formation is part of the Mago sedimentary mega sequence in the Tabas block that was located in the northern margin of the Neotethys Ocean in Jurassic-Cretaceous. The Baghmshah Formation in this section with 270m thickness mainly includes the alternation of...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
This article is presented in two parts. The first part is a study of the term "Tabaseyn" in the historical and geographical texts - from the 3rd century up to now. Through reliance on the sources, the author has come to the conclusion that prior to the 6th century A.H., Tabaseyn (the two Tabases) was not applied to Tabas-e _orma-and Tabas-e 'Annan which were later mentioned as Tabas-e Gilaki a...
large reserves of coal in tabas region of iran are characterized by low ash and high caking index, suitable for use in metallurgy as coking coal. however, these coals cannot be gainfully utilized because of their high sulfur content. in this work, studies on desulfurization of tabas coals were carried out in a batch reactor using various reagents. the most effective reagents, fe2(so4)3 , fecl3 ...
Introduction: Quaternary basalts are one of the last signs of magmatism in Iran, some of which are related to deep fractures and active faults in the Quaternary. Quaternary basalts of Tabas are very important due to their high expansion and location in eastern Iran, and are located 140 km south east of Tabas city and according to the proposed divisions are part of the Lut zone. The aim of this...
tabas mines in iran have coal sources which are suitable for use in metallurgy industries as coking coal. but the high sulfur content of this coal imposes severe limitations on its utilization as the sulfur oxide gases evolved from the combustion of high sulfur coals result in acid rains and corrosion of equipments. in this work, attempts have been made to reduce sulfur from high sulfur coal of...
