| 摘 要： | 通过对广东信宜贵子地区地质构造发展演化阶段和地质事件分析，确定地壳具有多旋回演化的特点，经历了地槽发展阶段（新太古代-早古生代）、准地台发展阶段（中泥盆世-早石炭世）和大陆边缘活动带阶段（晚三叠世-全新世）3个大地构造演化阶段.依据矿床成矿地质条件、矿产类型的研究，对各时代的成矿作用进行了总结，确定调查区内存在3个主要成矿期.根据矿床成矿作用、成矿时代、矿产分布和矿床地质特征探讨了找矿方向，在区内共划分出11个找矿远景区.

| Abstract: | Based on the analysis of the tectonic evolution and geological events in the Guizi area, Guangdong Province, it is confirmed that the crust in the area is characterized by multi-cycle evolution, with developing stages of geosyncline (Neoarchean-Early Paleozoic), paraplatform (Middle Devonian-Early Carboniferous) and continental margin mobile belt (Late Triassic-Holocene). With research of metallogenic conditions and mineral types, the metallogenesis in different epochs is analyzed. Three major mineralization periods in the studied area are determined. In the light of metallogenesis, oreforming times, distribution of deposits and the geological characteristics of deposits, the prospecting direction is discussed. Totally 11 ore prospective areas are delineated. |
