This study concerns the lithologic characteristics of stone used as main construction materials ancient Korean tombs, and aims to understand how they were supplied. Specifically, we investigated tombs in Songpa district, south Hangang River Seoul, composing connected stone-mound Seokchon-dong tomb complex, Bangi-dong No. 3, 13 horizontal stone-chamber Gamil-dong complex. There are major differe...

The residual strength of rocks and rock masses is an important parameter to be constrained for analysis design purposes in many engineering applications. A envelope principal stress space typically developed using data obtained from compression tests on different specimens the same type. In this study, we examined potential use continuous-failure-state testing concept as a means constrain limit...

In carrying out attendance activities, most schools still use the manual method, which utilizes book as a medium. However, presence of causes some problems that arise when using this method. With aim study, "Facial Recognition-Based Attendance System" was created. This study used Local Binary Pattern Histogram (LBPH) method to detect and recognize faces. The system is made student's face name, ...

Decades of research have resulted in characterization the ocean floor manifestations mid-ocean ridge (MOR) hydrothermal systems, yet numerical models accounting for connections between heat transfer, hydrology and geochemistry been slow to develop. The Thermo-hydro-chemical code ToughReact can be used describe coupled effects fluid flow, fluid-rock chemical interactions that occur MOR systems. ...

This paper reports the first discovery of basic igneous rocks in Bairin Right Banner southeastern Inner Mongolia, China. To understand genesis and tectonic evolution these rocks, we have carried out geochronology geochemistry research on them. The results show that LA-ICP-MS zircon U-Pb concordant mean ages massive basalt, diabase, pillow basalt are 272.0 ± 2.8 Ma, 261.5 3.2 256.5 2.5 respectiv...

The Midcontinent Rift System of North America is a ?1.1 Ga large igneous province comprising mainly flood basalts and intrusive rocks. We present new data for the Pillar Lake Volcanics Inspiration Sill from northern edge in northwestern Nipigon Embayment. comprise ?20–40 m thick, flat-lying sequence mafic pillowed massive flows, flow breccia, hyaloclastite breccia. They are characterized by SiO...

[1] Analysis of Martian gravity and topography implies that crustal thickness variations created in the earliest evolution of planet have persisted to the present day. Relaxation of crustal thickness variations due to lower crustal flow by thermally activated creep is strongly temperature-dependent and so, for particular crustal rheology and thickness, provides a constraint on thermal evolution...

Small bodies of granophyre occur as a volumetrically insignificant but ubiquitous component of the Banded series of the Stillwater Complex. White to pink granophyre typically occurs as veins, 1-12 cm thick and as much as 100 m long. A geochemically similar body of coalescing alaskite dikes, associated with an occurrence of Pt-group elements in the Banded series of the complex, crops out approxi...
