Abstract: The Baiyin copper ore-field of Gansu Province is characteristic of a particular fold structure consisting of anticlines with volcanic rocks as their cores, .so called volcanic-rock-core anticlines (VCA) by the authors.The styles of folding manifested by the volcanic and sedimentary rocks are differed from each other,and reveal that they have been subjected to different kind.s of formation mechanisms in the processes of folding and flattening. The primary inclinations of volcanic domes and the harmonic deformation of different lithological layers both are the requirements for the location, deformation and development of VCA.
