The deep roots of subduction megathrusts exhibit aseismic slow slip events, commonly accompanied by tectonic tremor. Observations from exhumed rocks suggest this region the interface is a shear zone with frictional lenses embedded in viscous matrix. Here, we use numerical models to explore transient characteristics finite-width frictional-viscous megathrust zones. Our model utilizes an invarian...

Using an apparatus which presents simultaneously the components for binocular color mixing to each eye and an additive, comparison mixture of the components to both eyes, an investigation was made of the effects of stimulus size, exposure time, and surround on the frequency with which the observers reported matching binocular mixtures. A comparison of binocular with additive mixtures as a funct...

In this paper we present a new algorithm to recover a sparse signal from a noisy register. The algorithm assumes a new prior distribution for the sparse signal that consists of a mixture of a narrow and a broad Gaussian both with zero mean. A penalty term which favors solutions driven from this model is added to the usual error cost function and the resultant global cost function is minimized b...

Lying along the south of Mongol–Okhotsk Suture Belt (MOSB) in Horqin Right Middle Banner Inner Mongolia, Chuhuertu granite is exposed Duerji tectonic melange. Based on systematic field geological characteristics, petrology, geochemistry, and zircon U-Pb chronology, we determined petrogenesis pluton setting, provide evidence for dominant factors magmatism study area. LA-ICP-MS dating showed an a...

In the late Middle to early Late Jurassic carbonate-clastic Sirogojno Melange in Zlatibor Mountain there is one roughly 35 m thick overturned block with an intact Triassic fore-reefal Dachstein Limestone succession studied for its biostratigraphic age, content and microfacies characteristics. The starts coarse-grained rudstones followed by meter-sized reefal blocks intercalated partly layered r...

Abstract The detection and characterization of young planetary systems offer a direct path to study the processes that shape planet evolution. We report on discovery sub-Neptune-sized orbiting star HD 110082 (TOI-1098). Transit events we initially detected during TESS Cycle 1 are validated with time-series photometry from Spitzer. High-contrast imaging high-resolution, optical spectra also obta...

Research subject. Nephrite and related rocks from the Nyrdvomenshor deposit in Polar Urals were studied. The is located exocontact of Rai-Iz ultramafic massif, confined to Main Ural Fault. was developed process geological exploration; a license has been issued for part deposit. Aim. To study nephrite alluvial deposit, formulate model its origin. Methods. Qualitative characteristics assessed vis...

The Tianshui-Sunjiaxia area is located in the connection zone of West Qinling Orogen and North Qilian Orogen, which could provide great insights into amalgamation processes between northern southern blocks China. Three subduction- rift-related rocks gneissic granite from arc-interarc belt (NQAI) metabasalt back-arc basin (NQBA) are distinguished across zone. was generated by melts older crustal...

baft ophiolite mélange is a part of naein-baft ophiolite (southeast of kerman province in iran). serpentinites from baft ophiolite mélange contain different types of spinels such as chromite, chromespinel, ferritchromite and magnetite which can reveal different stages of evolution in host serpentinites. the compositions of baft chromites show that they belong to podiform chromitites that may ha...
