湖北黄梅复式岩体位于大别造山带南缘，其从老到新可分为乱泥滩、向对门、长邓家、石地洼、月行坳等5个单元，归并为黄梅超单元。岩石地球化学分析研究表明，黄梅复式岩体具I型花岗岩特征，为同源岩浆结构演化序列。依据本次野外地质观测，并结合前人研究显示，该复式岩体形成于白垩纪晚期中国东部岩石圈减薄环境下。
湖北黃梅複式巖體位于大彆造山帶南緣，其從老到新可分為亂泥灘、嚮對門、長鄧傢、石地窪、月行坳等5箇單元，歸併為黃梅超單元。巖石地毬化學分析研究錶明，黃梅複式巖體具I型花崗巖特徵，為同源巖漿結構縯化序列。依據本次野外地質觀測，併結閤前人研究顯示，該複式巖體形成于白堊紀晚期中國東部巖石圈減薄環境下。

The Huangmei complex rock mass, Hubei lies at the southern fringe of the Dabie orogen, and is divided from old to new into 5 units as Luannitan, Xiangduimen, Changdengjia, Shidiwa and Yuexingao, which are termed the Huangmei super-unit as a whole. Petrogeochemical study indicated that the complex rock mass is characterized by I-type granite and is of comagmatic structural evolution series. Based on this field geological observation and previous research results, the complex rock mass is thought to be formed in late Cretaceous lithospheric thinning environment in eastern China.
