Processes of Holocene terrace formation in a steep gravel-bed river, Nikko volcanic area, central Japan
Flume experiments suggest that, in a breaded stream, terraces are formed from bars under erosional conditions. This paper examines these processes of terrace formation with the aid of field data on the Holocene terraces of the Nedori River
The genesis of terraces in the three gorge valley of the Yangtze River
Based on field survey, chemical and mineral analyses, archaeological data, radiocarbones dates, and pollen diagram, a hypothesis is presented that the rock planes of terraces and their overlying gravels and fine flood sediments were developed
Terrasses fluviatiles au Proche-Orient. in Colloque AFEQ, Paris 1983. (Fluviatile terraces in Near East)
Field survey in Lebanon, Syria and Jordan proves essentially that the terraces of the coastal rivers were built during marine regressions. Those of the inland rivers were roughly synchronous, as evidenced by the typology of the artefacts and various
Marine terraces, active faults and tectonic history of Iwo-jima.
Iwo-jima is a volcanic island situated 1 200 km south of Tokyo and is known by its very rapid uplifting (more than 10 cm per year). Marine terraces occupying nearly the whole island are classified in more than 20 treads, the highest of which is 120
Summarizes the results of recent researches and some problems on the Holocene sea-level change in Japan. The studies are concentrated on the areas of large coastal plains. Uplifting areas fringed by the Holocene marine terraces (south Kanto, Rynkyn
islands have been also intesively studied. Most Japanse sea-level curves are characterized by higher sea-level of ca. 6000 y. B. P. which followed rapid sea-level rise accompanying the deglaciation. Subdivision of the terraces was probably caused by co
Loess deposits are widespread within the piedmont and intramontane depressions of Central Asia. They cover piedmont plains, river terraces, ridge slopes and watersheds. Loess is a significant component in the piedmonts of Tien Shan, eastern Fergana
Program of the symposium and field trip to Niigata and Sado Island. Effects of human impact on sea-level changes, active neotectonics and difficulties of correlation between uplifted marine terraces.
paleosols, TL, paleomagnetic and fission track dating techniques have been applied to determine the age of the loess horizons. Correlations are made with the terrace of the Yellow River and oxygen isotope curves of the Pacific deep-sea cores and the Vostok
Slope features described as alluvial terraces or as a catenary compound of stony loessial sierozen are shown to be remains of former colluvial-loessial aprons. The loess was deposited in the central Negev during the uppermost Pleistocene by dust
, soil erosion, low level of transport and technological provision. Much effort should be made in terracing hill slopes, full utilization of grassland for animal husbandry, reafforestation and development of tree crops and fishery. (TNC).
Irrational use of the hilly regions of South China includes high proportion of land under forestry of low timber productivity, continuing expansion of terracing for growing rice, monotonous species used in afforestation, and frequent changes
