Vestfold salts database, analyses and photographs
A regional chemical boundary termed the 'salt line', in the Vestfold Hills of East Antarctica, was investigated using X-ray diffraction and electron probe analyses of surficial salts, and conductivity of surficial sediments. West of the salt line, halite and thenardite are abundant. These...

A regional chemical boundary termed the 'salt line', in the Vestfold Hills of East Antarctica, was investigated using X-ray diffraction and electron probe analyses of surficial salts, and conductivity of surficial sediments. West of the salt line, halite and thenardite are abundant. These salts are derived from dispersal of marine aerosols, saturation of sediment by seawater during postglacial marine transgression, and glacial dispersal of salt-saturated fjord bottom sediments. East of the salt line, subglacial calcium carbonates and salts formed by chemical weathering of their substrates may be found. The weathering products are formed from chemically and morphologically diverse minerals, which include two minerals not found previously in Antarctica, dypingite and hydromagnesite, and the first confirmed occurrence of brushite. The field descriptions, analytical data and photographs used to make these determinations are contained on the AADC server and are available through the WWW. An Electron Probe Microanalyser (EPMA) was used to perform the analysis of samples.
