Abstract
RECONNAISSANCE STATE OF LAKE MARL DEPOSITS IN THE OLSZTYN VOIVODSHIP
Summary
The present author pays attention to the rich lake marl deposits occurring in the northern area of Poland, and discusses their reconnaissance degree in the Olsztyn voivodship area. It is commonly accepted that the genesis of these deposits has greatly been influenced by biogeochemical processes, the intensity of which has been expressed in time and space by numerous factors. So far, approximately 100 deposits are known to occur in the Olsztyn voivodship area. Their total resources in natural state amount to 100 mill. m3.
Certain perspective exist of discovering new deposits, as well. A possibility of practical use of this mineral raw material for constructional, industrial and agricultural purposes has Jong ago been determined. At present, the lake marl is used mainly to enrich the acid soils in lime.
