The results of 118 REE analyses of Li-F granites from South China and other countries indicate that there are three variation ty pes of REE model curves with the different evolution from early to late stages of Li-F grantie complex or from lower to upper petrofacies of the Li-F granite body, which are (1) decreasing,(2) increasing and (3) saltatory variation types. The first variation type is called positive evolution type, which is the production of crystallization differentiation.

But detail geochemical study indicates (Wu et al., 2002)that those rocks have low Sr〓(0.706), high ε〓(-0.5~-1.9), young age of Nd model age (970-1090Ma) and syngenesis with surrounding I-type granites. The rock originated from partial melting of source igneous rock and belongs to I type granites. The occurrence of high alumina minerals is related to the intense interaction of magma and liquid during the late period of magma evolution, and tetrad REE patterns are formed.
但详细的地球化学研究表明(Wu et al。,2002),岩体具有低的Sr〓(0.706)、高ε〓(-0.5~-1.9)、年轻的Nd模式年龄(970-1090Ma)及与周围Ⅰ型花岗岩的共生关系,认为岩体是火成岩源岩物质部分熔融的产物,属于Ⅰ型花岗岩,高铝矿物的出现与岩浆演化晚期强烈的岩浆—流体相互作用有关,并形成特征的稀土元素四分组效应。

Based on soil radon gas survey in Quanzhou City and Jinjiang City, the authors conducted an investigation of the soil radon gas environment in an area of some 465 km2. The results indicate that radon gas concentrations in soils of Quanzhou and Jinjiang urban areas are at a lower level, whereas those in soils of Quanzhou and Jinjiang suburbs are at a fairly high level. It seems that the radon gas concentration is mainly related to geological background: radon gas concentrations in soils derived from weathering of adamellite, moyite, and biotite schist are higher than those in soils derived from weathering of other rock types.
通过泉州市、晋江市土壤中氡气测量,取得约465 km2土壤氡气环境调查成果,从结果来看,泉州市区和晋江市区土壤中氡气浓度普遍较低;市郊主要为山地,土壤中氡气浓度普遍较高;从土壤中氡气浓度水平的分布来看,土壤中氡气浓度水平主要与地质背景有关,二长花岗岩、钾长花岗岩、钾长浅粒岩及黑云片岩风化土壤中氡气浓度明显高于其他地质背景来源土壤。
