Is Jammu bauxite a reworked basalt derived bauxite?

摘要

The sedimentary structures in the bauxite deposits of the Jammu area are suggestive of a reworked bauxite precursor. Trace elements and REE concentrations show that the precursor bauxite originated from the weathering of basalt. It means that the bauxite forms a part of the earliest interval of the Himalayan foreland sedimentary sequences.
