Abstract:
The Bario/Kelabit Highlands, located in northern Sarawak is famous for its
rice. One of Bario’s hidden treasures, however, is its salt, produced from the
many salt springs in the area but sold in small quantities at the local
marketplace such that its existence is not well known outside of Sarawak. The
Bario salt is probably of non-marine origin but its actual origin is not clear.
A new salt analysis, in the context with older salt spring data, has enabled a
comparison with other non-marine salts. In particular, the presence of borate
and lithium points to potential affinities with non-marine highland salts, such
as those found in Argentina, Bolivia, Nevada and Tibet, as well as with
phreatic brine salt such as the Jadar deposit in Serbia. The marked content of
iodine makes allusion to brines in the vicinity of hydrocarbon-bearing
reservoirs. Given that the Bario salt contains hardly any sulphate, and very
little calcium, the source of the salt is unlikely to be an evaporite-bearing
rock in the subsurface as previously thought. Nonetheless, there should be more
fieldwork conducted and analyses made on the highland salt deposits and
associated brines in northern Sarawak to provide a better understanding of
their geochemical composition and origin.
