皖南浅变质岩分布区是古陆？还是一个造山带？这是华南大地构造研究中长期争论的一个重要问题。本文根据最新的研究资料，论证了它是一个由变质古生代地层组成的造山带，而不是一个古陆；同时讨论了这个造山带的结构组成和演化历史；最后讨论了这个造山带的演化历史在本区油气田勘探中的意义和需要进一步工作的建议。
Wannan shallow metamorphic rock distribution area is the ancient land? Or a orogenic belt? This is an important issue in the mid-term debate over the tectonics of South China. Based on the latest research data, this paper proves that it is a orogenic belt composed of metamorphic Paleozoic strata rather than an ancient land. The structural composition and evolution history of this orogenic belt are also discussed. Finally, the evolution history of this orogenic belt is discussed Significance of Oil and Gas Field Exploration in this Area and Suggestions for Further Work.
