Theories of Ore-Genesis

Genesis of Two Algebraic Theories of Language

1.1 In the present paper, we present our view of how two algebraic theories of language, formulated and developed at about the same point in linguistic history, came into existence. The theories and their variants we have chosen to this end are, on the one hand, the standard theory of transformational grammar, formulated in the mid-1960’s by Noam Chomsky, and, on the other hand, an early versio...

Ore mineralogy and fluid inclusions constraints on genesis of the Muteh gold deposit (western Iran)

The Muteh gold deposit (NE of Golpaygan) in the central part of intrusive-metamorphic belt of Sanandaj-Sirjan zone comprises NW-SE trending gold-quartz vein occurred in metamorphic complex. Gold mineralization is associated with quartz veins that formed during regional deformation across the mylonitic zones in metamorphic rocks of predominantly meta-volcanic, gneiss and schist. The sulfidation ...

Mineralogy, geochemistry and genesis of Temelieh Manganese ore Deposit (NorthWest of Selseleh, Lorestan Province)

Temelieh area is located about 20 Km northwest of Selseleh (Lorestan Province). Geologically, the area is a small part of the Harsin radiolarite complex. Petrography consists of radiolarite, peridotite, gabbro, plate dikes, basalt and andesite, limestone, and marble. Manganese mineralization occurs as vein-veinlet and is mainly formed in faults, joints, and fractures that crosscut in radiolarit...

Theories underlying requirements engineering: an overview of NATURE at Genesis

Requirements engineering is perceived as an area of growing importance. As we learn more about the nature of requirements information, the traditional task of requirements capture as an early stage in the life cycle is complemented by several new applications of the models it produces, and of the processes that generate these models: • the explicit and computer-supported use of requirements, es...
