Jadwiga Joanna Orska (8 March 1923 – 28 January 2004) was a Polish geologist, petrographer, and specialist in the geology of chemical raw materials deposits, particularly salts. She was the co-discoverer of a deposit of polyhalite salts in the area of the Bay of Puck in the southern Baltic Sea, off the shores of Gdańsk Pomerania, Poland.[1]

Early life and education

Jadwiga Orska was born on 8 March 1923. She earned her secondary school certificate in 1946 at the Jan Kochanowski Secondary School in Warsaw. From 1948, she worked at the Polish Geological Institute. She completed three years of geological studies at the Faculty of Geology of the University of Warsaw, followed by two years at the Faculty of Geology and Exploration of the AGH University of Science and Technology in Kraków. In 1962, she earned a master's degree in geology.[2]

Career

Between 1955 and 1958, Orska worked on mapping the underground workings of the Kłodawa salt mine, working out the petrographic composition of the documented salts. From 1961 she headed the Pracownią Petrografii Soli Zakładu Złóż Soli i Surowców Chemicznych Państwowego Instytutu Geologicznego (the Salt Petrography Laboratory of the Department of Salt Deposits and Chemical Raw Materials of the Polish Geological Institute). She conducted mineralogical, petrographic and physicochemical studies of salt rocks of the Góra, Lubień, Damasławek, Kłodawa and Łętkowice-Siedlec salt deposits.[3] She also studied Zechstein halite Permian rock layers from deep boreholes in the Polish Lowlands.[2]

Following the discovery of Zechstein polyhalite salts in the Puck Bay area in 1964, Orska was involved in their identification and documentation. For the discovery and documentation of these salts, she was awarded the Nagrodę Państwową II Stopnia Technology prize in 1968.[2]

During 1969, she studied Alpine rock salt deposits at the University of Vienna, Austria and the University of Basel, Switzerland through a six-month United Nations scholarship. In 1970 she was awarded the Golden Cross of Merit by the Polish state.[2]

In early 1976, Orska took over the management of the Department of Salt and Chemical Raw Materials of the State Geological Institute. At that time, the department carried out prospecting, identification and documentation of Zechstein and Miocene deposits of rock salt and potassium-magnesium, phosphorites and other chemical raw materials. In 1980, it received an award for Geological Documentation of a category C rock salt deposit in the Lubień salt diapir.[2]

Orska was the author or co-author of numerous publications and more than 30 archival studies.[2]

Later life

Jadwiga Orska died in Warsaw on 28 January 2004.[2]
