The Surk ophiolitic mélange is located at the south west of central Iran and along the Naein-Dehshir-Baft ophiolitic belt. In petrological sequence, peridotites are nominated the undermost part of rock unit, and then gabbros and volcanic rocks are at the following ranks respectively. The predominant peridotitet of this ophiolitic mélange is harzburgite. Lherzolite that is the primitive mantle r...
Abstract The European Organization for Nuclear Research (CERN) is currently undertaking a feasibility study to build the next-generation particle accelerator, named Future Circular Collider (FCC), hosted in 90–100 km subsurface infrastructure Geneva Basin, extending across western Switzerland and adjacent France. This article represents preliminary, basin-scale stratigraphic lithotype analysis ...

the felsic pegmatitic rocks are exposed in the north of golpayegan. the dominate mineral assemblage is quartz, k-feldspar, plagioclase, muscovite, tourmaline and garnet. the elevated spessartine content of the garnets in the studied rocks along with their idiomorphic shape, the absence of resorption feature and garnet-free country rocks may point to their magmatic origin and crystallization at ...
