Liuhe gold orefield is being newly explored in the southeast part of Jiapigou ore belt, and occurs Neoarchean basement composed trondhjemite–tonalite–granodiorite (TTG). Zircon U–Pb data suggest that ore-hosting magma emplacement mainly took place two epochs: late to early Paleoproterozoic (ca. 2500 Ma) Jurassic Mesozoic era 170 Ma). The TTG rocks show higher A12O3 (12.58 15.71%) Na2O/K2O ratio...

Pleistocene basaltic lava flows, consisting of trachybasalt and basaltic trachyandesite, cover an area north-northwest of Shahre-Babak in southeastern Iran. The whole rock chemistry indicates that the lavas are dominantly alkaline and mildly calc-alkaline. Variation diagrams of SiO2 with major and trace elements are consistent with fractional crystallization processes involving olivine, pyroxen...

[1] The plate motion of India changed dramatically between 50 and 35 Ma, with the rate of convergence between India and Asia dropping from 15 to 4 cm/yr. This change is coincident with the onset of the India-Asia collision, and with a rearrangement of plate boundaries in the Indian Ocean. On the basis of a simple model for the forces exerted upon the edges of the plate and the tractions on the ...

The present-day motions in and around the Arabian plate involve a broad spectrum of tectonic processes including subduction, continental collision, seafloor spreading, intraplate magmatism, transform faulting. Therefore, good constraints on relative rates directions, possible deformation, are crucial to assess seismic hazard at boundaries areas within it. Here we combine GNSS-derived velocities...

The far western Aleutian Island Arc is actively colliding with Kamchatka. Westward motion of the Aleutian Arc is brought about by the tangential relative motion of the Pacific plate transferred to major, right-lateral shear zones north and south of the arc. Early geologic mapping of Cape Kamchatka (a promontory of Kamchatka along strike with the Aleutian Arc) revealed many similarities to the g...

We present a theoretical analysis of fluid flow and particle interactions in the cone-plate viscometer under conditions typically applied in biological studies. The analysis demonstrates that at higher shear rates, besides linear primary flow in the rotational direction, prominent non-linear secondary flow causes additional fluid circulation in the radial direction. Two parameters, the cone ang...

We developed a kinematic earthquake cycle model applicable to transform fault zones, subduction zones, and collision zones on the basis of elastic dislocation theory. The crustal deformation associated with the periodic occurrence of interplate earthquakes is generally given by the superposition of viscoelastic responses to steady slip on the whole plate boundary, steady back slip on the seismi...

In this contribution, a simple uniaxial compaction of granular materials is considered in preparation for studying the collision behavior double-hull vessels filled with materials. The top compressing plate deformable and modeled by finite element method (FEM). particles using discrete (DEM) are compressed plate. To end, partitioned technique to couple continuum approach (FEM) particle discreti...

Surface-induced dissociation (SID) and collision-induced dissociation (CID) are ion activation techniques based on energetic collisions with a surface or gas molecule, respectively. One noticeable difference between CID and SID is that SID does not require a collision gas for ion activation and is, therefore, directly compatible with the high vacuum requirement of Fourier transform ion cyclotro...
