利用区域地物化资料,采用多元统计方法及GIS空间分析技术,通过对东天山成矿带中黄山铜镍矿床、小热泉子铜锌矿床的地质、地球物理、地球化学特征的分析,对东天山西段进行了有色金属矿床找矿靶区预测。预测结果认为:色尔特能、铜花山—硫磺山、米什沟、马鞍桥、彩华沟是今后找寻大型有色金属矿床的重要靶区。     

南海1∶100万永暑礁幅海洋区域地质调查成果

1∶100万永暑礁幅海洋区域地质调查成果揭示了该区地壳的浅、中、深层地质特征。浅层主要研究海底地形、地貌、表层沉积物、矿产资源、潜在地质灾害等；中层主要研究新生代地层、断裂体系、岩浆岩、含油气盆地远景等；深层则研究磁性基底、深层断裂、莫霍面分布特征等。本成果在以下几方面有重要突破：①通过对比新生代以来的地层,确定各沉积盆地地层特征和相互关系,在此基础上预测油气资源前景；②分析表层沉积物类型,预测本区未来可能具有开发价值的固体矿产资源；③利用磁性基底和莫霍面数据分析本区地壳结构特征。

新疆且末县迪木那里克铁矿床地质特征与找矿潜力分析

新疆且末县迪木那里克铁矿床位于阿尔金山南缘大断裂东南侧。通过大量的野外地质工作和室内分析,发现矿体严格受地层控制,产于长沙沟构造蛇绿混杂岩带之中,赋矿岩石以千枚岩为主,属于沉积变质型磁铁矿矿床。初步确定矿区存在一个大的向斜构造,已对主矿体(F e36、F e37)进行了工程控制,新增资源量3 003万t。矿体向深部和外围的延伸情况还未完全控制,而且矿区外围存在大量航磁异常有待进一步查证。说明该矿找矿潜力巨大。     

赞比亚西北省铜-钴矿地质及找矿潜力

[摘 要]赞比亚位于著名的中非新元古代沉积型铜（-钴）矿带上,铜带省和西北省是该国最主要的铜-钴矿集中分布区;相对于找矿程度已经很高的铜带省,西北省成矿地质条件优越,且地质工作程度较低,因此拥有巨大的找矿潜力,已成为该国找矿突破的重点区域。目前西北省主要著名的矿山/矿床有3个：坎桑希、卢穆瓦纳、卡伦比拉。这些铜-钴-金-铀-镍矿床的含矿地层、矿化特征与铜带省传统经典的沉积型铜-钴矿既有相似性,又明显具有差别。本文通过对西北省区域地质和已发现矿床地质特征的介绍,对该省的找矿潜力进行初步分析。

Ore-Bearing Formations of the Precambrian in South China and Their Prospects

In the Precambrian System of the Yangtze and Cathaysian plates six ore-bearing formations can be identified: the Cu-Pb-Zn-bearing formations in volcanic rocks of marine facies of the Neoarchean-Paleoproterozoic, Cu-Au-bearing formations and Pb-Zn-bearing formations in volcanic rocks of marine facies of the Mesoproterozoic, Pb-Zn-bearing formations in volcaniclastic rock and carbonate rock of the Neoproterozoic, Fe-Mn-bearing formations in the volcaniclastic rock of the Neoproterozoic, and Ni-Cr-serpentine-bearing formations in ophiolite and ultrabasic rock of the Meso- and Neoproterozoic. They were mostly formed in the marginal rift valleys of the Yangtze and Cathaysian plates, where occur stratabound and stratiform ore deposits, thermal deposits and porphyry polymetallic deposits. The six regions with ore-bearing formations have good prospects for ore deposits.
