Petrographic and geochemical studies characterize lithologies of the Khambal Formation deposited in the Sindreth Basin as arkosic, subarkosic, and quartzarenite. Weathering indices, such as CIA and CIW in conjunction with the ACNK diagram, prescribe mostly moderate chemical weathering with intermittent pulses of extreme weathering in the source area. The discrimination diagrams suggest that these Neoproterozoic clastics were deposited in an active rift basin. Provenance indicators of the detritus components point to a terrane possessing subordinate mafic material in conjunction with large felsic components. A comparison of immobile element ratios with probable source rocks suggest that the Mesoproterozoic Delhi arc situated to the east of the Sindreth Basin could be the possible source. Our mixing calculation defines the proportion of end member components in the Delhi arc. Geodynamic considerations relate the origin of the Sindreth Basin to the processes of disintegration and reassembly of supercontinents.

岩石学和地球化学研究将沉积在信德斯盆地的Khambal地层岩性描述为arkosic，subarkosic和石英亚砷酸盐。诸如CIA和CIW以及ACNK图之类的耐候性指标规定了源区域内的中等耐候性以及间歇性极端耐候性脉冲。鉴别图表明这些新元古代碎屑沉积在一个活跃的裂谷盆地中。碎屑成分的来源指示物指向具有附属的镁铁质物质和大的长质成分的地层。将固定元素比率与可能的烃源岩进行比较表明，位于信德斯盆地东部的中元古代的德里弧可能是可能的烃源。我们的混合计算定义了德里弧段中最终成员组成的比例。地球动力学方面的考虑将信德斯盆地的起源与超大陆的分解和重新组装过程联系在一起。
