摘要:
文章对江西甲路幅1:5万重力调查实测数据进行处理与解释,推断并构建了甲路幅断裂构造体系,解释了主要断裂的形态、延伸及性质。结合磁测异常圈定了研究区内的隐伏岩体,并通过2.5D解释确定了主要岩体的外接触面形态与埋深; 通过对区域典型矿床地质、物化探异常特征研究,结合地质、化探资料对该区成矿远景进行圈定与预测。通过研究构造、岩体、成矿三者之间的关系,认为断裂控制岩浆与热液的运移,进而控制隐伏岩体及内生型金属矿床的发育与空间展布。与其他物探方法相比,重力调查在解释断裂构造方面具有自身特色与优势,是配合矿产地质调查查明断裂、隐伏岩体及隐伏矿床的最佳物探方法之一。
Abstract:
Through process and interpretation of the measured data of 1:50 000 Jialu Sheet gravity survey in northeastern Jiangxi Province, this study infer and reconstructs the structure system of the Jialu Sheet, and explains the morphology, extension and nature of the main faults. Combined with the concealed intrusions in the study area, which were outlined by magnetic anomalies, their external contact surface morphology and depth were determined using the 2.5D interpretation. Based on geologic and geochemical anomalies of typical ore deposits in the region, the metallogenic prospect areas were delineated and predicted. Study of relationship between tectonics, intrusions and metallogenesis suggests that the faults controlled the migration of the magma and hydrothermal fluids, and then controlled development and spatial distributions of concealed intrusions and endogenous metal deposits. Compared with other geophysical survey methods, gravity survey has its own advantages in explaining fault framework, and should be one of the best geophysical methods to identify regional structures, hidden intrusions and concealed deposits in mineral geological survey.
