Most Plio-Pleistocene sites in the Gregory Rift Valley that have yielded abundant fossil hominins lie on the Rift Valley floor. Here we report a new Pliocene site, Kantis, on the shoulder of the Gregory Rift Valley, which extends the geographical range of Australopithecus afarensis to the highlands of Kenya. This species, known from sites in Ethiopia, Tanzania, and possibly Kenya, is believed t...

Blasting demolition plays an important role in building demolition, and numerical-simulation methods can facilitate the optimization of blasting-demolition schemes. To study influence delay-time differences between columns on blasting effect small-aspect-ratio reinforced concrete structures, a separated common node model structures was established through finite element numerical simulation sof...

study of tectonic affects in many fluvial systems shows that, rivers are valuable tools to active tectonics surveying. study of stream channels and their associated deposits offset by faulting may reveal the amount displacement at particular site and give information that is critical for future earthquake hazards evaluation. study area which is a subbasin of atrak river is located at the ne ira...

We test the valley-filtering capabilities of a quantum dot inscribed by locally straining an $\alpha$-$\mathcal{T}_3$ lattice. Specifically, we consider out-of-plane Gaussian bump in center four-terminal configuration and calculate generated pseudomagnetic field having opposite direction for electrons originating from different valleys, resulting valley-polarized currents, conductance between i...

[1] Ma’adim Vallis, one of the largest valleys in the Martian highlands, appears to have originated by catastrophic overflow of a large paleolake located south of the valley heads. Ma’adim Vallis debouched to Gusev crater, 900 km to the north, the landing site for the Spirit Mars Exploration Rover. Support for the paleolake overflow hypothesis comes from the following characteristics: (1) With ...

during this survey 29 sites have been recognized totally. settlement patterns determined base of environmental characteristics such as altitude, ground slope, source of water, petrology and geology, vegetations, land use and specifications of sites including width, chronology, regional distribution and density and all of them have been divided by using geographic information systems (gis) and c...

Karangsambung, located in Central Java, Indonesia has complex geological conditions of the tectonic evolution Java Island due to subduction process India-Australia plate with Eurasian Cretaceous-Paleocene. The movements zone have resulted diverse structures and rock types impact morphological shape study area. level activity area can be determined using a geomorphological approach. A digital el...

The morphotectonic analysis is a useful time-saving and cost-effective method to assess tectonic activity, especially in large regions. In this paper, the study was carried out Kerman city which southeast of Iran part Central structural zone. Despite occurrence numerous historical instrumental earthquakes around city, there gap earthquake records that has obscured its seismicity status. aim ide...

The present study aims to describe and bring out the tectonic nature of Ijai watershed in parts Kangpokpi, Tamenglong Noney districts Manipur. has an area 184.0 Km2which is also tectonically active as depicted by analysed values different geomorphic indices like SLK index, Valley Floor Width Height ratio (Vf),Transverse Topographic Symmetry (T), Drainage Basin Asymmetry (AF), Elongation Ratio (...
