A020 Z-99 Mapping resistivity variation to identify sulphidic sediments in Sweden. Introduction 1 Sulphidic postglacial sediments occur below the highest coastline in both Finland and Sweden. The sediments were mainly deposited in the Litorina Sea from about 7000 to 4000 years ago. Acid sulphate soils are formed after oxidation of the iron sulphides (e.g. FeS FeS2) in these sediments. High concentrations of certain trace elements (e.g. Ni Cu and Mn) have been measured in streams which drains areas dominated by acid sulphate soils [9]. These trace elements can cause environmental problems. Figure 1. Location of the Study area in the
