Bondono granite-gneiss body is located in the core of Toutak anticline, located 200 km NE of Shiraz. This granitoid mass, which is a part ofToutak metamorphic complex, is exposed on the Sourian sheet. Petrological studies determined that the mentioned rocks are placed in orthogneiss field. Based on current studies, the geochemical, tectonic setting and geochronology characteristics of the Bondo...
The Sumatran GPS array spans approximately 1300 km along the West coast of Sumatra, Indonesia. Almost 40 monitoring stations periodically collect high accuracy continuous GPS readings, and convey these to a central server for post-processing in Singapore. Solutions from the array data are used to provide precise measurements of the deformation of the earth's surface over large distances: in eff...
Oceanic iron inputs must be traced and quantified to learn how they affect primary productivity and climate. Chemical reduction of iron in continental margin sediments provides a substantial dissolved flux to the oceans, which is isotopically lighter than the crust, and so may be distinguished in seawater from other sources, such as wind-blown dust. However, heavy iron isotopes measured in seaw...
introduction: diabetes mellitus is an growing national and international public health concern. the number of people affected by diabetes in world by 2030 will be 69% in developing countries. regular physical activity plays a key role in the management of type 2 diabetes melitus, particularly glycemic control. it has been recommended that peoples with type 2 diabetes participate in moderate-int...
Earthquakes normally occur as frictional stick-slip instabilities, resulting in catastrophic failure and seismic rupture. Tectonic faults also fail in slow earthquakes with rupture durations of months or more, yet their origin is poorly understood. Here, we present laboratory observations of repetitive, slow stick-slip in serpentinite fault zones and mechanical evidence for their origin. We doc...
Sagami Bay is an active tectonic area in Japan. In 1993, a real-time deep sea floor observatory was deployed at 1,175 m depth about 7 km off Hatsushima Island, Sagami Bay to monitor seismic activities and other geophysical phenomena. Video cameras monitored biological activities associated with tectonic activities. The observation system was renovated completely in 2000. An ocean bottom electro...
Conductivity models beneath the Nanga Parbat Haramosh Massif (NPHM) derived from magnetotelluric soundings reveal that there is no widespread, interconnected, conductive aqueous fluid to minimum depths of 40 km below sea level. Given the continuing tectonic denudation, young granitic and migmatitic bodies indicating partial melt at shallow crustal depths, and active seismicity, this result is s...
