Stylolite networks in dolomitized limestones and their control on polished decorative stones:a case study from Upper Cretaceous Khur quarries, central Iran
Stylolite networks and their insoluble residues (IR) are among the major concerns and the fundamental controls on the mining and processing of sedimentary decorative stones, largely made from dolomitized limestones. They are mainly used, as natural rock blocks and polished slabs, to construct and decorate floors and walls of buildings and monuments. Representative quarries in Khur areas, east o...
متن کاملUpper Turonian – Santonian slope limestones of the Islands of Premuda , Ist and Silba ( Adriatic Coast , Croatia )
Upper Turonian–Santonian limestones at three island locations (Ist, Silba and Premuda) in the southwestern part of the Adriatic carbonate platform, record slope deposition based on their sedimentological and palaeontological characteristics. These Upper Cretaceous successions consist of three vertically superimposed lithotypes: (1) pelagic mudstonespackstones, (2) laminated pelagic wackestones-...
متن کاملIntroducing some echinoderms from the Tirgan Formation, Kopeh-Dagh Basin, NE of Iran
A stratigraphic section from the Tirgan Formation was selected in Arkan village nearby Bojnourd city in order to study echinoderm fauna systematically. Many specimens of echinoderms, especially toxasteridae which is associated with brachiopods were collected and studied systematically in this paper. Microscopie slides were also prepared and studied. All slides contain benthic foraminifers and c...

The bentonites of Aftar region, with average of 15 meters thickness and about 10 km long, are volcanoclastic sequence of Semnan Formation that formed in a shallow sea water environment. Based on the field, XRD data, microscopic and scanning electron microscopic (SEM) studies, as well as chemistry, the bentonite beds contain zeolites (clinoptilolite and mordenite), gypsum, calcite, celestine, op...
متن کاملInvestigations of gold-sulfide mineralization and microthermometry within quartz veins/veinlets in the Gharehchay area, south of Tikmehdash, East-Azarbaidjan province, NW Iran
The gold-bearing prospect area at Gharehchay is located in about 2 km south of Tikmehdash, East-Azarbaidjan, NW Iran. The host rocks of the gold-bearing quartz veins/veinlets are principally Eocene andesites and upper Eocene-Oligocene felsic intrusive body (granite to alkali granite). Wall rocks alteration haloes developed around the veins/veinlets are mainly of silicic, phyllic, phyllic-argill...
