A Ghazi; N Hafezi Moghadas; H Sadeghi; M Ghafoori; G Lashkaripour

Volume 24, Issue 94 , March 2015, , Pages 17-28

https://doi.org/10.22071/gsj.2015.43111

Abstract
  In this study, engineering geomorphology of MashhadCity is evaluated. For this purpose, aerial photos of the city, 180 drinking water wells and 1500 scattered geotechnical boreholes have been studied. Based on this information, the city divided into 6 geomorphologic units including rock outcrop, pediment, ...  Read More

Compositional Zoning in Feldspars of the Kuh-e Dom Intrusive Rocks

F Sarjoughian; A Kananian; J Ahmadian

Volume 24, Issue 93 , December 2014, , Pages 133-146

https://doi.org/10.22071/gsj.2014.43554

Abstract
  The alkali feldspars and plagioclases in the Kuh-e Dom intrusive rocks show compositionally and microtexturally zoning structure. The feldspar crystals in the various lithologies such as granite- granodiorite samples, diorite- gabbro samples and relatively high frequency microgranular mafic enclaves ...  Read More

Zoning of RQD Parameter, Based on Faults and Self-Organizing Map in Semilan Dam Site

A. Hossein Morshedy; H. Memarian

Volume 21, Issue 84 , December 2012, , Pages 99-112

https://doi.org/10.22071/gsj.2012.53962

Abstract
  Zoning is an important practice in earth sciences. In zonation, the study area is divided into separate parts and by compiling the results of these parts, a unique model is obtained. In this study, clustering methods are applied for zoning of Semilan dam site. Optimal number of clusters are measured ...  Read More

Origin of Zoned Pyroxene in the Daykes of Sub Alkali Andesite of Hassan-Abaad Village of Yazd- South-West of Taft

S. Zandifar; M. V. Valizadeh; M. A. Barghi; M. R. Foroodi Jahromi

Volume 20, Issue 77 , January 2010, , Pages 151-156

https://doi.org/10.22071/gsj.2010.55366

Abstract
  In the west and north west of Hassan-Abaad village of Yazd, massive dikes of alkali andesite in the diorite, quartz diorite and granodiorite are observed. Clinopyroxene phenocrysts in these rocks have obvious zoning. Reconnaissance work indicates that groundmass pyroxenes in the alkaline rocks are similar ...  Read More

Investigation of Plate Bearing and Settlement in South-Eastern and East Tehran

F. Rezaei; M. Eivazi

Volume 19, Issue 73 , January 2009, , Pages 71-78

https://doi.org/10.22071/gsj.2010.57202

Abstract
  The Tehran city, capital of Iran is located on young alluvium deposits which mostly cover due to rapid urban development. This urban development without proper geotechnical and geological assessment may cause great engineering and economic problems. Survey of geotechnical problems are one of the most ...  Read More
