Abstract

Abstract

In this paper, wavelet multi-scale analysis/boundary identification method/continuous complex wavelet time-frequency analysis/3D magnetization inversion are used to process and interpret gravity and magnetic data in the southeast Hubei Province. It is found the follows. (1)The Shanpo-Fenglin deeply-penetrating fault is north dipping and shallow part shows shape of "S", of which middle-western section deviates to south and east section deviates to north as a result of transformation in Indo-Chinese epoch and Yanshanian. It has controlled the formation and distribution of rock mass in Indo-Chinese epoch and Yanshanian. Echeng/Tieshan/Jinshandian/Lingxiang rock masses are dominated by iron ore on the north. Yangxin/Yinzu/Guojiaqiao rock masses are dominated by copper polymetallic ore on the south. (2) Magma chamber is located in deep, with a depth of about 5 km. Magma intruded upward and emplaced through weakness structure, which formed mid-shallow and exposed rock mass in the shape of bead/apophyses/dike. (3) There may exist concealed ore body in south of Echeng rock mass/north of Tieshan rock mass/east part of the south margin of Jinshandian rock mass. The areas where Chenjiawan exposed rock mass/Jinniu-Xiaojiabian exposed rock mass/west of Lingxiang exposed rock mass are in contact with carbonate beds are favourable for mineralization.
