一九五九年五月我院继58年在闽中和闽东南进行大规模普查和找矿的基础上,继续进行区测工作。工作区域是永安、龙岩和永定以西,包括连城、长汀、上杭及武平等地。本文材料主要来自我院59年区测的成果及刘庆发、陈曼多,张仲馨、张自恒四同学所收集资料,在工作过程中,鲍正启、徐书策、刘锡汗、邓家铣及金庆云等五位同学协助进行了一些实际鑑定工作。 本区火成岩分布很广,特别是花岗岩类侵入岩非常发育,几占总面积的三分之一以上。过去一般都认为它们是燕山期的产物。如陈愷在1942年就曾提到这样的结论:“闽境花
In May 1959, on the basis of 58 years of large-scale general survey and prospecting in Central Fujian and Eastern Fujian, our hospital continued to carry out the district survey. The working area is Yong’an, Longyan and Yongding west, including Liancheng, Changting, Shanghang and Wuping. The materials of this paper mainly come from the results of 59 years of our hospital and the data collected by Liu Qingfa, Chen Mando, Zhang Zhongxin and Zhang Ziheng. Through the work, five students from Bao Zhengqi, Xu Shusai, Liu Xikhan, Deng Jia milling and Jin Qingyun helped Some practical identification.
