王弭力  浦庆余 《地质论评》2004,50(6):566-566
今年《地质论评》已出版50卷。我国超过50卷的学术刊物是很少的,《地质论评》刊出50卷是个值得庆贺的时刻。《地质论评》1936年创刊,1951年出到第16卷时,与“Bulletin of Geological Society of China”《中国地质学会会志》(英文、法文、德文)合并为中文版的《地质学报》。随着地质工作的蓬勃发展和国际交流日益频繁。中国地质学会事理会会议决定恢复《地质论评》,  相似文献

The coastal zone of the Sagar island has been studied. The island has been subjected to erosion by natural processes and to a little extent by anthropogenic activities over a long period. Major landforms identified in the coastal area of the Sagar island are the mud flats/salt marshes, sandy beaches/dunes and mangroves. The foreshore sediments are characterized by silty, slightly sandy mud, slightly silty sand and silty sand. Samples 500 m inland from high waterline are silty slightly sandy mud, and by clayey slightly sandy mud. The extent of coastline changes are made by comparing the topographic maps of 1967 and satellite imageries of 1996, 1998 and 1999. Between 1967 and 1999 about 29.8 km2 of the island has been eroded and the accreted area is only 6.03 km2. Between 1996 and 1998 the area underwent erosion of 13.64 km2 while accretion was 0.48 km2. From 1998 to 1999, 3.26 km2 additional area was eroded with meager accretion. Erosion from 1997 to 1999 was estimated at 0.74 km2 /year; however, from 1996 to 1999, the erosion rate was calculated as 5.47 km2/year. The areas severely affected by erosion are the northeastern, southwestern and southeastern faces of the island. As a consequence of coastal erosion, the mud flats/salt marshes, sandy beaches/dunes and mangroves have been eroded considerably. Deposition is experienced mainly on the western and southern part of the island. The island is built primarily by silt and clay, which can more easily be eroded by the waves, tides and cyclonic activities than a sandy coast. Historic sea level rises accompanied by land subsidence lead to differing rates of erosion at several pockets, thus periodically establishing new erosion planes.  相似文献

The tectonic history of Sri Lanka - India can be traced from the Precambrian to the present. On the basis of the geological record, plate tectonic processes have operated for example, the Highland Group of Sri Lanka may have represented a Precambrian plate tectonic suture. Tectonic models of these Precambrian events may be presented by spreading, collision, subduction, shearing or in situ jostling. The recent tectonic history of Sri Lanka and India relates to the evolution of the Indian Ocean since at least the Cretaceous. Although Sri Lanka is considered to be a part of the larger Indo - Australian plate, it may have had a local independent history as a block within the larger crustal unit of India. There is evidence that the separation of Sri Lanka from India was in part controlled by Precambrian structures and a history of translational, rotational and vertical adjustments to the Indian Ocean developmental plate tectonic stresses still operating.  相似文献

Chloritoid-sericite schists from the chlorite zone of the regionally metamorphosed Singhbhum anticlinorium in Eastern India are described with regard to the formation of chloritoid during prograde metamorphism — the main stage of its crystallisation was coeval with the movement. The movements accompanying metamorphism have had a marked effect on the lattice orientation of this mineral, so that its crystallographic axis is roughly parallel to the regional fold axis. In one case chloritoid appears to be in stable association with hematite, i.e. it persists beyond the magnetite-hematite equilibrium, which is probably a local effect due to a slight rise in oxygen partial pressure in the last stages of metamorphism. The occurrence of phengitic mica in these schists is suggestive of high total pressures and high water pressures.  相似文献
