THE DEFORMATIONAL TEXTURE OF THE BANXIA ANTICLNE AND ITS BEARING ON ENGINEERING GEOLOGY OF MIDDLE QINGJIANG RIVER IN WESTERN HUBEI

After a brief description of the geological settings of the two dam sites located re-spectively in Shuibuya and Banxia in the middle reaches of the Qingjiang river of westen Hubei province'an analysis of the deformational textures of the Banxia anticline was made in terms of its characteristic geometry, intraformational fold, axial plane cleavage and sec-ondary fault.The texture was formed and developed in the major phase of Yanshanian move-ment.The major engineering geological conditions of these two dam sites sitting on opposite limbs of the anticline are controlled by its deformational texture.
