周家湾片麻状花岗岩体位于湖北省大悟县大悟山南麓。岩体规模不大,但其所处地质构造条件复杂,附近又发现多种有色金属及非金属矿产,故近几年来为我省广大地质工作者所重视,在该区投入了较多的地质工作。由于工作深度不够,长期以来对岩体的时代及成因一直存在着不同的意见。一九七三年一比二十万黄陂幅地质报告将该岩体定为燕山早期花岗岩侵入体;一九七九年一比五万小河镇幅及一九八一年松林岗幅地质报告则又将其
Zhou Jia Wan gneiss granite body is located in Dawu County, Hubei Province Dawu Shan south. Rock mass is not large in scale, but its geological conditions are complex, and a variety of non-ferrous and non-metallic minerals are found in the vicinity. Therefore, in recent years, it has been paid great attention to by geological workers in our province and more geology has been invested in this area jobs. Due to the insufficient depth of work, there have been different opinions on the age and cause of rock mass for a long time. In 1973, the 1: 200,000 geological reports of the Yellow River boreal zone set the rock mass as the early Yanshanian granite intrusion. The 1979 -50,000-kilogram and Geological Report of 1981-Songlin Post Turn it again
