It has been shown in the Al(Na+K+Ca/2) diagram that the Jinla granitoids are all plotted within the area of "S" type of granites, but the samples from Laochang amphibole admellite, Menglinshan biotite admellite and Nanla K-feldspar graniteporphyry are scattered gradually far away from the boundary between "I" and "S" types of granites, implying that the components from the upper mantle gradually decreasing from the Laochang amphibole admellite to the Menglinshan biotite admellite and then to the Nanla K-feldspar granite porphyry.
3上述三类花岗岩样品皆位于S型花岗岩区,但从老厂似斑状角闪二长花岗岩,勐林山似斑状黑云二长花岗岩,到南腊碱长花岗斑岩,样品分布逐渐远离"I"型花岗岩和"S"型花岗岩的分界线,这表明自老厂似斑状角闪二长花岗岩至勐林山似斑状黑云二长花岗岩,到南腊碱长花岗斑岩幔源组分逐渐减少。

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。
