摘要：

摩洛哥大阿特拉斯构造带位于特提斯成矿域西端,成矿地质条件优越,已发现大量MVT型铅锌矿床(点),但长久以来较低的地质工作程度使得铅锌成矿潜力不明。中大比例尺地球化学调查是资源勘查的有效手段,准确的地球化学异常信息能快速圈定找矿远景区,提高勘查效率和成功率。本文通过摩洛哥大阿特拉斯构造带东段万余平方千米区域的1∶100 000地球化学调查,查明该区水系沉积物中铅元素含量为5.7~43 210.0 μg/g,平均含量为45.0 μg/g;锌元素含量为12.2~75 420.0 μg/g,平均含量为86.4 μg/g,均高于地壳克拉克值。以 92% 累频为异常下限(Pb含量为36.9 μg/g,Zn含量为78.3 μg/g)共圈定73个铅地球化学异常和68个锌地球化学异常,通过铅、锌等元素的地球化学分布特征,结合区域地质背景和成矿条件分析,划出了3个主要铅锌成矿带,成矿带内进一步圈定了9处铅锌矿找矿远景区,提出该区具有寻找MVT型铅锌矿的潜力。该成果为下一步开展找矿勘查提供了重要方向。

Abstract:

The Moroccan High Atlas tectonic belt is located at the west end of the Tethyan metallogenic domain with favorable geological conditions for mineralization. Numerous Mississippi Valley-type lead-zinc deposits (MVT) have been discovered in this region. However, the mineralization potential of lead and zinc is unclear due to lack of long-term, high-level geological investigation. Medium- to large-scale geochemical surveys are effective tools for resource exploration, as detailed geochemical anomaly information can help to quickly delineate prospective mineralization areas, thereby improving the exploration efficiency and success rate. In this study, a 1∶100000 geochemical survey was conducted over an area of more than 10000 km² in the eastern section of the Moroccan High Atlas tectonic belt. The results revealed that the lead content in stream sediments ranged from 5.7 to 43,210.0 μg/g, averaging 45.0 μg/g, and the zinc content ranged from 12.2 to 75,420.0 μg/g, averaging 86.4 μg/g. Both values are higher than the Clarke values of the Earth’s crust. Using the 92% cumulative frequency as the anomaly threshold (Pb=36.9 μg/g, Zn=78.3 μg/g), a total of 73 lead and 68 zinc geochemical anomalies were delineated. By analyzing the regional geochemical distribution characteristics of lead and zinc, combined with the regional geological background and mineralization conditions, three major lead-zinc metallogenic belts were identified, and nine lead-zinc ore prospective areas were delineated. This study suggests that the region has significant potential for discovering MVT deposits, providing important directions for future mineral exploration efforts.
