Abstract A late early Maastrichtian dinosaur trampling site is reported from the Farrokhi Formation of Khur area, Central Iran. The largely indeterminate footprints, some which may represent undertracks, can be classified as natural moulds (i.e. concave epireliefs) bordered by a raised rim displaced sediment. They reach diameters up to 0.5 m and were impressed under very shallow subaerial condi...
bentonite deposits of economic interest are widespread in tashtab mountains (khur), east of isfahan province, iran. several bentonite deposits have been developed in this area as a result of eocene volcanic alteration. these deposits are classified as khur bentonite horizon. xrd analyses reveal that alteration products consist of na-montmorillonite, kaolinite, quartz, calcite, and crystobalite....
Dioritic plutons and pinkish alkali-feldspar granitic dikes of Kalateh area (northwest of Khur city) intruded in Neoproterozoic basemental of Jandagh- Arousan complex. Field observations, petrography and geochemical studies indicate that these intrusive rocks have I-type nature and belong to medium-high K calc-alkaline granitiods and also have genetically relationship with each other.
