武当地块是指出露于武当山和郧西-郧县地区、卷入南秦岭构造带中的前震旦纪浅变质过渡基底地块(图1)。基性岩墙群在该地块中广泛发育,并在南秦岭区域的同类地块(如其东延的随-枣地块)中普遍存在,成为南秦岭地质的一大特色,在秦岭-大别造山带早期形成演化研究中具重要意义。我们首次对基性岩墙群进行了系统研究,本文提供的地质信息对重新认识本区有关基础地质问题、深入探讨秦岭带早期地质特征具有重要意义。
The Wudang block refers to the pre-Sinian epithermal basement exposed in the Wudang and Yunxi-Yunxian tectonic belts (Figure 1). The basic dyke swarms widely develop in the block and exist universally in the similar blocks in the South Qinling area (such as the Su-Ju date block in the East Yan), becoming a major feature of the South Qinling geology. In the Qinling-Large It is of great significance to study the evolution of the early formation of orogenic belt. For the first time, we systematically studied the basic dyke swarms. The geological information provided in this article is of great significance to re-understanding the basic geological problems in this area and exploring the early geologic features of the Qinling belt.
