摘要
超大型矿床是当前地球研究的前沿课题，但目前对超大型矿床的概念及划分仍无统一的认识。超大型金矿床在国外分布广泛，类型众多，成矿时代广，矿床规模大，控矿构造特殊。对超大型金矿床的找矿重点是研究全球成矿背景及成矿理论，对现有大型矿床进行进一步评价以及采用先进手段进行新区预测。目前中国虽肯定的超大型金矿床不多，但从中国所处的特殊地质条件以及现有矿床勘探程度较低等情况来看，具有良好的找矿前景。
The study on superlarge mineral deposits is one of new world frontier projects in earth sciences, but up to now,there is no united understanding of its concept and terminology . The superlarge gold deposits are characterized by widespread distribution, various types, metallogenic epoches, huge dimension and special tectonic conditions abroad. Studies on global metallogenesis of superlarge gold deposits, progressive evaluation of large gold deposits and prognosis of new regions based on advanced techniques are important to search for new superlarge gold deposits. In view of farorable geological conditions and poor exploration of current gold deposits,brilliant prospects will appear in China for discovery of superlarge gold deposits.
