摘要
本文分三部分，首先阐述了岩浆侵入作用形成的环形构造图象显示特征。其次，结合物化探 异常、钻探资料、以及地表地质、矿化和围岩蚀变等资料论述了侵入岩体的存在。最后探讨了它 的形成机制。
This paper is composed of three parts. Firstly, the show features from landsat images of the several ring-like structures formed by magma intrusi- vism on the Yangzi River in Anhui are described. Secondly, combining remote sensing with other informations, the existance of the intrusive batholiths are discussed from geophysical and geochemical prospecting anomalies, drilling informations, and the surface geology, oveszation and altered wallrocks and so on. Finally, it is discussed to form the process of the ring-like structures in simple.
