ÉRTEKEZÉSEK - Dr. Székyné Fux Vilma: Inkey Béla Mexikóban

BÉLA INKEY AT THE Xth INTERNATIONAL GEOLOGICAL CONGRESS, MEXICO B. INKEY (1847—1921) was one of the most outstanding Hungarian geologists carrying out pioneering activities in several fields. Originally he studied law and after finishing his studies he worked in the Ministry of Cultural Affairs and was in charge of the College for Mining and Metallurgy. Then, from 1874 on, he became a student of the Mining Academy at Freiberg. Returning home he found a job at the Royal Hungarian Geological Institute, then upon the invitation of the Royal Hungarian Society for Sciences he performed mining geological surveys at Nagyág (Transylvanian Ore-Mountains). In the meantime, in the S Carpathian Mts., from the break-through of the river Olt to the Vaskapu pass of the river Danube he undertook the task of geological mapping along a stretch of 200 km, and within two years he compiled the outline geological map of the region. After his father's death he retired from geology and was engaged in farming. After organizing the Department for Agrogeology at Royal Hungarian Geological Institute, B. INKEY was appointed to lead it. He performed the first agrogeological survey in Hungary, and published the first Hungarian agrogeological map (1892). At the Xth IGC held in Mexico in 1906 he lectured on the origin of ores and had considerable success according to the foreign colleagues. In his lecture (De la relation entre l'état propylitique des roches andésitiques et leurs filons minéraux) he discussed in details the preliminary ideas concerning the Grünstein. In his lecture INKEY emphasized that the Hungarian J. SZABÓ was the first to recognize the fact that the propylite is not an independent rock type but an andésite coming from the centre of the volcanic sequence that was transformed upon the influence of vapours, gases and hot water solutions (1870). The primary aim of his lecture was to call attention to the close relation of the propylization and ore genesis based on his investigations in Nagyág. His own investigation at Nagyág also proved the righteousness of J. SZABÓ's ideas. He goes further, however, and points out that there is a basic difference between the propylization and the kaolin formation accompanying the veins. Propylization is characterized by chlorite and carbonate formation, and trying to find the reasons for the joint appearance of the propylization and ore veins he also discussed the problems of their relation and the origin of the ore material. In his opinion the variegated silicates of the parent rocks of the veins, first of all the heavy metal trace elements of the amphiboles and pyroxenes are leached by vapours, gases and aciduous hot water solutions and they are accumulated, in the form of ore filling in the parent rock as veins. His summing up the ascendent and lateral theories of the secretional ore genesis is still modern, so the success he achieved by his lecture is quite understandable. The end of World War I made him very disappointed and at the age of 74, in 1921 he died. Based on his oeuvre he belongs to the group of the most eminent, pioneering Hungarian geologists whose fundamental ideas are still valid.
