一九五九年六月到九月期间,我们参加了北京地质学院所组织的赣东北区测大队,在江西上饶鷹潭间浙赣铁路之南北进行1/20万填图工作。图幅面积约7000多平方公里。主要在上饶、铪山、横峰、弋阳,贵溪等五个县份内。该区交通方便,矿产丰富,过去有很多地质工作者进行过研究,但多偏重于地层和矿产方面,而对于岩浆岩注意的很不够。本文愿就我们所见到的一些情况,着重对酸性浸入岩的特征及时代问题提出一些粗浅的看法。 本区地质构造此较复杂,地层出露齐全,只缺失志留纪和泥盆纪的沉积。共中以前震旦纪之千枚岩、片岩及第三纪之红色沙岩,砾岩分布最广。由震旦纪到三叠纪各时代地层多分布于本区东部,而且构造形态比较完整。西部则主要是前震旦纪变质岩系和中生代的地层。
From June to September 1959, we participated in the survey team of the Northeast Jiangxi Province organized by the Beijing Institute of Geology and conducted 1 / 220,000 mapping work in the north and south of the Zhejiang-Jiangxi Railway at Yingtan-Zhengtienhe-Jiangxi Railway in Shangrao, Jiangxi Province. Map format area of about more than 7000 square kilometers. Mainly in Shangrao, Hafnium Hill, Hengfeng, Yiyang, Guixi and other five counties. The area is easily accessible and rich in mineral resources. In the past, many geologists conducted research, but most of them focused on strata and mineral resources, but they did not pay enough attention to the magmatic rocks. This article is willing to some of the conditions we have seen, focusing on the characteristics of acid dipped rocks and the times put forward some superficial views. This area of the geological structure of this more complicated, complete stratum, only missing Silurian and Devonian sediments. Before the Central Plains, Sinian phyllites, schists and Tertiary red sandstones were the most widely distributed. Stratums from Sinian to Triassic are distributed in the eastern part of the area, and their tectonic forms are relatively complete. The west is mainly Pre-Sinian metamorphic rocks and Mesozoic strata.
