bouin- miandasht granitoid pluton (bmgp), which outcropped to the north of bouin-miandasht- aligoudarz road, was emplaced into low to medium grade of triassic to early jurassic metapelitic rocks of sanandaj-sirjan structural zone. in this study we do provide the first investigations of bmgp by means of anisotropy of magnetic susceptibility (ams). most km values for the main felsic compositions ...

The morphology of subaqueous landslide deposits is seldom analyzed quantitatively or at least semi-quantitatively with regard to the dynamics of the flow. However, the peculiar morphology of the deposits can reveal information on the mechanics of propagation of the mass movement and on the mechanism of emplacement. Horseshoeshaped deposits and oriented blocks are two peculiar morphologies of su...

Geol., 58 :47 -61 The transportation mode for large, isolated clasts "f loating" in turbidites is a problem that has been difficult to resolve. New observations from experimental, high-density turbidity currents indicate that large, outsized clasts can be transport...

Introduction: Lunar pyroclastic deposits can be subdivided into several modes of occurrence [1], suggesting different modes of emplacement. For example, some smaller pyroclastic deposits have been interpreted to have erupted during strombolian/hawaiian activity [2], while others are linked to vulcanian activity related to dike and sill emplacement below crater floors [3,4]. The largest pyroclas...

During the Cretaceous, the South China Block (SCB) experienced a widely distributed extensional event including numerous plutons emplacement and basin opening. Investigations on the tectonic regime coeval with pluton emplacement, and emplacement mechanism of the pluton remain relatively rare in the SCB. In order to address these questions, a multidisciplinary approach, including field structura...

The analysis of Anisotropy of Magnetic Susceptibility (AMS) is a powerful and rapid technique to examine the preferred orientations of mineral (magnetic) fabrics and can indicate the nature of a magma transport (vertical or lateral). The relationship between magnetic fabric and geometry of a dyke swarm enables us to understand magma emplacement processes. Depending on the mutual relationship of...

Diamonds formed during the Proterozoic and Archaean and are in-homogenously distributed in the mantle below Archaean cratons. Kimberlite magmas usually form well within the diamond stability field and physically incorporate seemingly random amounts of diamonds during their ascent through the mantle. The diamond content of a kimberlite magma arriving at the earth’s surface is defined by ascent p...
