The Tethyan Himalaya is the fourth metallogenic belt discovered to date within Tibetan Plateau and contains chromite, gold Sb–polymetallic mineralization. records a series of complex tectonic–magmatic events that include break-up, subduction, collision, detachment, obduction Eastern Gondwana continent, all which generated ideal conditions for ore formation. However, this area remains under-expl...
The Kahnuj ophiolitic complex, a part of the Jazmurian ophiolitic belt, is located on the western boundary of the Jazmurian depression and is bounded by two major fault systems. There is a well-preserved, ophiolite pseudostratigraphy of early Cretaceous to early Palaeocene age and has a bearing on the Mesozoic development of southeastern part of Iran and adjacent region. The Kahnuj ophiolitic c...
The Kuh-e Mish plutonic complex (KPC) is located about 30 km south of Sabzevar. Based on tectonic division, it is part of Sabzevar zone. The Stratigraphic units of the area are conglomerate, tuff, and sandstone of the Paleogene, radiolarites, andesite and tuff unit of Upper Cretaceous. This collection consists of two plutonic rocks types. (1): The granitoid complex of northern Kuh-e Mish which ...
The first occurrence of the belemnite species Liobelus acrei (formerly Acroteuthis acrei) is reported from Lower Cretaceous (Valanginian) Vocontian Basin (VB; south-east France). This record genus (Family Cylindroteuthididae), which commonly attributed to latest Jurassic and Early Boreal Realm, revises spatial distribution pattern boreal belemnites significantly. Valanginian assemblages VB are ...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
A Valanginian to Barremian bathyal foraminiferal assemblage (118 taxa belonging to 51 genera) is documented from ODP Site 766, drilled near the foot of the Exmouth Plateau off northwest Australia. The majority of taxa are cosmopolitan species previously described from the boreal assemblages of northern Europe and the northern margins of the Tethys, but 32 taxa could not be assigned to previousl...
