一、前言所谓辽西地区是指辽西沿海錦县以西山海关以东錦西、兴城、綏中三个县份所包括的范圍,也就是相当于燕辽沉降带的南部边緣与山海关地块相接壤的活动地带。这一地区不論在構造、岩漿活动和成矿作用上都有它自己的区域特点,是一个有意义的地区。 1955年王之田等曾以“辽宁西部五子山—虹螺山区域地質与矿产的調查报告”为題,对該区进行了比較系統的研究,初步的总結了前人的工作。从前人的文献中可以看出区域岩漿活动的分期以及其范圍的圈定尚存在着分岐的意見。
I. Preface The so-called western Liaoning area refers to the area covered by the three counties of Jinxi, Xingcheng and Suizhong in the east of Xishan Customs in Jinxian County along the coastal area of western Liaoning Province, which is equivalent to the boundary between the southern edge of Yanliao Subsidence Belt and Shanhaiguan Plot Activity area. The area has its own regional characteristics in terms of tectonics, magmatism and mineralization and is a significant area. In 1955, Wang Zhida et al. Once conducted a systematic study on the survey report on the geology and mineral resources of the Wushan-Hongluo Mountain region in the west of Liaoning Province, and summarized the work of his predecessor initially. As can be seen from the literature of the predecessors, the staging of the regional magmatic activity and the delineation of its scope are still divided.
