The Zudong and Guanxi granites are original rocks of the ion adsorption-type HREE and LREE deposits in weathering crust of granites. The ΣREE value and LREE/HREE ratio of the Zudong granite are 264 ppm and 0.81-0.24 respectively, and the average Y/ΣREE ratio is 35.8-54.5%. This is mainly due to magmatic crystallization and evolution and deuteric metasomatism (albitization, muscovitization and fluorite-doveritization). These alterations resulted in endogenic mineralizations of yttrium-group REE fluorine carbonates, silicates and arsenates. The Guanxi granite is characterized by LREE enrichment (the average LREE/HREE ratio is 2.43).

Geotectonica et Metallogenia 1999年第2期23卷 155-165页

作者： Zhang Weimin(East China Geological Institute, Linchuan, jiangxi 344000, China)

The studies of water, gas and isotope chemistry indicate that the formation of geothermal water in the Henjing area is not related to the magmatic and volcanic sources. The geothermal water mainly derives from the meteoric source, and the gas components originate from the mixing of meteoric, crustal and mantle sources. Moreover, the geothermal water is in a low to moderate temperature geothermal reservoir. The results calculated by the quartz geothermometer and the silicaenthalpy diagram demonstrate that the lowest temperature of geothermal reservoir is in the range 78℃ to 134 ℃ and the highest temperature is in the range 95℃C to 155℃. Based on isotopic data, the possible elevation of recharge water is about 337. 5 m to 743. 6 m, which corresponds to the Wunizhang area.

The M5.7 Jiujiang earthquake in 2005 was a mid-strong one, stronger than expected to occur in the region. This paper discusses the neo-tectonic settings of this earthquake, and it is thought that the earthquake region is located in the transitional belt, a potential area inducing weak to moderately strong earthquakes, between two large different tectonic units. The results of the reconnaissance work and on-the-spot investigation after earthquake indicate that the occurrence of the M5.7 Jiujiang earth- quake is closely related with the NE-trending fault on the western margin of Ruichang Basin. From its controlling to the landforms and Quaternary depositions, geological profiles, ESR dating, etc., the ac- tivity of the Dingjiashan-Langjunshan fault bounding the basin is discussed. It suggests that this fault displays an active one in Middle Pleistocene by the outcrop. Based on the activity of the fault, and the direction and location of the ground fissures, the isoseismal lines and the nodal plane of the focal mechanism solution, it is inferred that the Dingjiashan-Langjunshan fault is the seismogenic tectonics of the M5.7 Jiujiang earthquake, and the intersection point between this fault and the active NW ones is the possible origin of location of this earthquake. Our study shows that this earthquake is not an event exceeding expectation, and that the active and invisible characteristics of the causative fault are typical in the eastern area of China.

Taking jiangxi Province as an example,on the basis of the sampling survey on 42 counties and cities,64 towns and 74 villages in jiangxi Province,the will of farmland transfer among different farmer groups with different income levels,different ages,and different educational backgrounds,is *** research indicates that as for middle-income or high-income groups,leaving home to seek jobs elsewhere is the most principal factor impacting farmland transfer,while as for low-income group,the price of agricultural products is an important factor impacting farmers’ land cultivation;permanent urban residence certificate is no longer the principal factor causing farmers’ land transfer,and it tends to be rational for farmers to abandon farmland.

The regional stress field and seismic dynamics along the border zone between Fujian, Guangdong and jiangxi Provinces are studied based on the seismo-geological data,GPS measurement, and seismicity. The results show that: (1) the principal compressional stress of the stress field is oriented in NW-SE direction and the principal extensional stress is in NE-SW direction; (2) the WNW-ward compression and collision of the Philippine Sea Plate to the eastern coast of Taiwan Island are the most direct and most important dynamic source for preparation and occurrence of strong earthquakes in the Taiwan Region and along the border zone between Fujian, Guangdong and jiangxi Provinces.
