Iodine and bromine as hydrogeochemical indicators of hydrocarbons in the mesozoic and paleozoic deposits of north Poland
Abstract
Increased contents of biophile elements found in subsurface brinewater are a very important factor in the search for crude oil, and it is assumed that brines containing more than 1 mg/l iodine and more than 100 mg/l bromine characterize a contact zone with hydrocarbon deposits. Data are presented which indicate that considerable amounts of iodine and bromine occur in the northern lowland areas of Poland, encompassing the Peribaltic syneclise, the Mazury-Suwalki elevation, the Pomeranian synclinorium and the Pomeranian anitclinorium. It is shown that the most promising deposits are Jurassic and Middle Bunter sandstone period deposits, which occur in the Pomeranian synclinorium, where the iodine content varies from 8.7 to 27.5 mg/l. In the Bunter sandstone brines encountered in the Western part of the Pomeranian synclinorium, the bromine concentration is as high as 2,000 mg/l, thus being one of the highest concentrations in the world.
