  Rezumat:  The ore deposits reference list in Romania was significantly enriched due to a new volume dedicated to the hydrothermal ore deposits. “Hydrothermal metallogeny” (Metalogenia hidrotermală), the fourth volume of Prof. Mârza’s monography devoted to magmatic derived ore deposits was recently published by “Presa Universitară Clujeană”. This new volume represents in fact the result of nearly a whole life of scientific activity, which comprises more than 180 original publications. Among Prof. Mârza’s main scientific contributions we may consign those volumes that altogether represent the first Romanian monography devoted to magmatic derived ore deposits that counts more than 1500 pages. The first volume (250 p.) was published in 1982 and it deals with general problems of magmatic metallogeny. The second volume (331 p.), published in 1985 tackles about orthomagmatic and pegmatitic metallogeny. Skarn and greisen petrometallogeny were the aims of the third volume (485 p.), published in 1992. The fourth and final volume, which is announced with this occasion, broachs the subject of hydrothermal metallogeny. A series of very important metals (Au, Ag, Pb, Zn, Cu etc.) are preferentially concentrated during hydrothermal activity in several genetic types of hydrothermal ore deposits. Among the Romanian metallogenetic resources, the best developed and the most important types of ore deposits from an economic point of view are the hydrothermal ones. Classic occurrences of hydrothermal ore deposits in the Eastern Carpathians as well as in the Apuseni Mountains are well known to the scientific community. These are only a few reasons why “Metalogenia hidrotermală” roses the interest of Romanian and foreign economic geologists. ...
