摘　　要：利用鄂尔多斯盆地重力资料进行了断裂构造的微弱信息提取,并在断裂构造的解释方面获得了新的认识,根据解释的鄂尔多斯盆地构造信息对成矿进行相关预测。采用延拓、方向梯度和垂直二阶导数等技术识别断裂构造,采用数字图象处理技术并VC++6.0编程实现。较准确地识别出重力资料所反映断裂构造的微弱信息异常,确定了鄂尔多斯盆地断裂构造的空间定位与展布。该方法提取了鄂尔多斯盆地区域重力异常资料中的断裂构造的微弱信息,有助于该区断裂构造解释和多种能源矿产空间定位的分析研究,为深入研究鄂尔多斯盆地的断裂构造和多种能源矿产预测提供了有利的证据。Using gravity data in Ordos Basin to extract the weak information of the rift structure, and acquiring the new understanding in the aspects of rift structure, carrying on the related forecasts towards metallization according to the structure information of Ordos Basin. Utilizing technology such as continuation, direction gradient and two derivatives methods etc to recognize the rift construction, exerting digital image processing technology to realize in terms of the VC ＋＋6.0 program. This method has extracted the rift structure＇s weak information of the gravity unusual records in Ordos basin. Contribute to the rift structure explanstion and the analysis researchs in the space position fixing of various energies mineral in that area, More accurately recognise out the weak information anomaly of the rift structure which gravity data reflected, ascertain the space position fixing and distribution of the rift structure in Ordos Basin. offer favourable evidence for thoroughly study the rift structure and various energies forecast in Ordos Basin.
