In the Precambrian Singhbhum stratigraphy, some enigmatic aspects exist as regards to Dangoaposi and Jagannathpur lavas. The existing enigma embodies locational aspects of these lavas, structural characteristics, stratigraphic position, and geochemical affinities. Based on recent field studies by the authors and knowledge acquired from existing literature, a possible solution has been proposed in the present study, which may be followed by Precambrian geologists in order to avoid all existing confusion and dilemma. The present study clearly indicates that in Jagannathpur, there is the presence of dyke rocks only (and there is no lava) and as such stratigraphic position of Jagannathpur lava in Singhbhum Geology should be discontinued. Dangoaposi lava (described as Jagannathpur lava by some previous workers) explicitly represents a portion of western Iron Ore Group (IOG) lava and therefore, may be considered to represent a sub-domain within western IOG.

印度东部 Singhbhum Craton 的 Dangoaposi 和 Jagannathpur Lavas 之谜：可能的解决方案

在前寒武纪 Singhbhum 地层中，Dangoaposi 和 Jagannathpur 熔岩存在一些神秘的方面。现有的谜团体现了这些熔岩的位置、结构特征、地层位置和地球化学亲和力。基于作者最近的实地研究和从现有文献中获得的知识，本研究提出了一种可能的解决方案，前寒武纪地质学家可能会遵循该解决方案，以避免所有现有的混乱和困境。目前的研究清楚地表明，在 Jagannathpur 仅存在岩脉（没有熔岩），因此应该停止 Singhbhum Geology 中 Jagannathpur 熔岩的地层位置。
