Mehmet Ozan Sungurlu, the legendary Turkish petroleum geologist

Abstract. On the occasion of 29 October 2023, the 100th anniversary of the Republic of Türkiye, I would like to pay tribute to M. Ozan Sungurlu (1939–1990), one of the most important non-academic competent Turkish field and petroleum geologists, and a pioneer of geological field observations throughout Türkiye. His scientific studies were published in numerous articles, many of which were co-authored by Turkish geologists. This article was written in memory and appreciation of M. Ozan Sungurlu, who made a great contribution to the field of geology in Türkiye and whose importance to Türkiye is undisputed. M. Ozan Sungurlu will be remembered as a valuable geoscientist whose passion and legacy we should share with future generations.
