Studies on a wide range of gold deposit types suggest that the crustal accumulation of gold throughout the Earth’s history was a consequence of changing tectonic regimes and variable paleo-redox conditions. The Singhbhum crustal province in eastern India is no exception to these events. The gold occurrences in the Singhbhum crustal province are confined to the Paleo-Mesoarchean greenstone belts within the Archean cratonic core region and the Paleo-to Mesoproterozoic North Singhbhum mobile belt (NSMB). Gold mineralization within the cratonic core region occurs either as greenstone hosted lode-gold or as modified paleoplacer gold terrains, whereas in the North Singhbhum mobile belt, gold is associated with quartz reefs and auriferous sulfides within rocks metamorphosed to greenschist-amphibolite facies. The concentration of gold within these Archean and Proterozoic terrains has been highly episodic with different sedimentary, metamorphic and hydrothermal mineralizing events operating during the respective periods. However, information regarding the genesis of gold in these occurrences remains fragmental and lacks regional-scale integration with the tectonic evolution of the Singhbhum crustal province. The present work provides a comprehensive review of the various gold occurrences/deposits in the Singhbhum crustal province and their possible genesis with respect to the tectonic evolution of the crustal province.

This work recognizes that the gold endowment of the Paleo-to Mesoarchean paleoplacers was influenced by the presence of underlying high-MgO komatiites, resulting in the lean Au-assays in these paleoplacer deposits. On the other hand, the Paleo-to Mesoarchean greenstone hosted lode-gold occurrences indicate a mafic proto-source from which Au was mobilized into the Paleoarchean ocean and fixed into the contemporaneous inter-layered carbonaceous sedimentary sinks, which was ultimately reconcentrated to economic grades with the advent of plate-tectonics and coeval metamorphism. From the Proterozoic onwards, tectono-metamorphic events took over as the driving mechanism for gold accumulation in the Singhbhum crustal province. Pervasive intraplate rifting and simultaneous deposition of organic matter rich black shales set the stage for a possible Au-rich carbonaceous sedimentary sink, similar to a wide-range of Proterozoic sediment hosted gold deposits.

对各种金矿床类型的研究表明，整个地球历史上金的地壳积累是不断变化的构造制度和可变的古氧化还原条件的结果。印度东部的辛格布姆地壳省也不例外。Singhbhum 地壳省的金矿仅限于太古代克拉通核心区的古中太古代绿岩带和古至中元古代北 Singhbhum 移动带（NSMB）。克拉通核心区域内的金矿化以绿岩为主的矿脉金或改良的古砂金地形发生，而在北 Singhbhum 移动带中，金与变质为绿片岩-角闪岩相的岩石中的石英礁和含金硫化物有关。这些太古代和元古代地层中的金浓度具有高度的偶然性，在相应时期发生了不同的沉积、变质和热液矿化事件。然而，关于这些矿点中金成因的信息仍然是零碎的，并且缺乏与 Singhbhum 地壳省构造演化的区域尺度整合。目前的工作对 Singhbhum 地壳省的各种金矿床/矿床及其与地壳省构造演化相关的可能成因进行了全面回顾。关于这些矿点中金成因的信息仍然是零碎的，并且缺乏与 Singhbhum 地壳省构造演化的区域尺度整合。目前的工作对 Singhbhum 地壳省的各种金矿床/矿床及其与地壳省构造演化相关的可能成因进行了全面回顾。关于这些矿点中金成因的信息仍然是零碎的，并且缺乏与 Singhbhum 地壳省构造演化的区域尺度整合。目前的工作对 Singhbhum 地壳省的各种金矿床/矿床及其与地壳省构造演化相关的可能成因进行了全面回顾。

这项工作认识到，古至中太古代古砂层的金禀赋受到下伏高 MgO 科马提岩存在的影响，导致这些古砂矿沉积物中的金含量贫乏。另一方面，古至中太古代绿岩中的矿脉金矿床表明金矿是一个镁铁质原源，金由此进入古太古代海洋并固定在同期的层间碳质沉积汇中，最终重新富集到经济等级随着板块构造和同期变质作用的出现。从元古代开始，构造变质事件成为 Singhbhum 地壳省金积累的驱动机制。
