摘要
福建省均口断陷带位于崇安－石城断裂带中部，是武夷山加里东隆起区在燕山期的重要活动形式之一。本文论述了均口断陷带的变形、火山、岩浆、沉积作用地质特征，并划分出34个燕山期的构造层。作者认为主要断层是区城扩张作用下形成的拆离断层，它们控制了各种地质作用，推测主断层为超壳断层。
The Junkou graben belt is located in the middle part of the Cong'an-Shicheng Fault Zonein the northwestern part of Fujian Province, and is one of the important forms of Yanshanianactivities of the Wuyishan Caledonian upwelling area. This paper introduces deformation,volcanic magmatic, sedimentary geological characteristics of the graben belf and the grabenbelt was divided into 34 Yanshanian structural layers. it's suggested that the main faults aredecollement faults formed by the regional spreading and the decollement faults controlvarious geological activities. However, it is inferred that the major fault is a transcrustalfault.
