| 中文摘要:新疆红海铜锌矿床是位于东疆卡拉塔格矿田的一个中型规模的隐伏VMS型矿床，开展成矿预测工作，对矿区生产探矿及周边找矿预测具有重要的生产实践和科学意义。文章以红海铜矿为研究对象，基于现有地质钻探数据，结合矿区地质特征，运用地质统计学方法，分析该矿床成矿规律、矿化趋势，构建了红海矿区三维限制性矿体晕模型，并将原生矿体晕栅格化并限制在蚀变域范围内研究其矿化趋势。在此基础上，进一步分析预测了勘探靶区，为该矿床的深部和边缘找矿提供了新的思路和方向，并在随后的生产实践中取得了找矿突破。研究取得了以下主要成果：（1）首次提出了限制性矿体原生晕模型的概念；（2）基于基础地质数据，构建了红海矿区的蚀变域模型，并根据地质统计学分析，建立了栅格化的铜元素三维限制性矿体蚀变晕模型；（3）利用限制性矿体原生晕模型，对三个方向趋势面进行了矿化趋势分析，并在三维空间内厘定了成矿靶区，直接推动了红海矿区隐伏矿体的找矿突破。 |

| Abstract:The Honghai copper deposit in Xinjiang is a medium-sized concealed VMS type deposit located in the Kalatage ore field in eastern Xinjiang. Prospecting prediction has important practical and scientific significance for production exploration of this deposit and prospecting prediction in the surrounding area. Taking the Honghai copper deposit as the research object, this work integrated existing geological drilling data and the geological characteristics of this deposit, and utilized geostatistical methods to analyze the mineralization laws and trends of the deposit. A three- dimensional restricted ore body halo model of the Honghai deposit was constructed, and the primary ore body halo was gridded and restricted within the alteration zone to study its mineralization trend. On this basis, further analysis and prediction of the exploration target area provided new ideas and directions for the deep and edge exploration of the deposit, and breakthroughs were made in subsequent production practices. The main achievements of this study are as follows: (1) the concept of a restricted ore body primary halo model was first proposed; (2) Based on basic geological data, a model of the alteration zone in the Honghai deposit was constructed, and a gridded three-dimensional restricted copper ore body alteration halo model was established according to geostatistical analysis; (3) By using the restricted ore body primary halo model, mineralization trends were analyzed in three directions, and the mineralization target area was determined in three-dimensional space, which directly promoted the breakthrough in the exploration of hidden ore bodies in the Honghai mining area. |
