Detailed sea depth data and hydrological observations for the first printed isobath map were collected by Marsigli in the Gulf of Lion three hundred years ago. This map, an annex to his large and comprehensive volume on the seas, has been considered one of the forerunners of thematic maps. Although the cartographic and oceanographic literature often refers to Marsigli’s map, several authors have misinterpreted the data and information contained in the map. This paper re-examines the map legend and the drawing of the map, compares the first isobath map with a modern map of the area, and finally evaluates Marsigli’s contribution to earth sciences.

The Tokaj Mts, situated in the northeastern part of the inner arc of the Carpathians, forms a part of a Miocene calc-alkaline andesitic-dacitic-rhyolitic volcanic island arc. The ancient volcanic structures were reconstructed on the basis of the 1:50 000-scale and 22 sheets of the 1:25 000-scale geologicpetrologic maps, as well as the revision of the volcanic facies in 150 boreholes. Multispectral and SAR satellite imagery, aerial photos, data and maps of airborne geophysical surveys (magnetic and radiometric), gravity-filtered anomaly maps, geochemical (soil and stream sediment Au, As, Sb, Hg) concentration distribution maps and the K/Ar dating of 132 samples from 80 paleomagnetic measurements were also used.
The anomalies were only taken into consideration in the interpretation if the coincident results of at least 3 methods indicated the presence of any volcanic structure. In consequence, 91 map-scale volcanic structures were identified by morphology — complex calderas, single lava domes, volcanic fissures, subvolcanic intrusions, diatremes, stratovolcanoes and postvolcanic formations. Conclusions were also drawn regarding the link to the volcanic structures and prospective occurrences of the mineral resources of the Tokaj Mts: andesite, dacite, welded zeolitic tuff, K-metasomatite, perlite, pitchstone, pumice, bentonitic, illitic, kaolinitic, diatom-bearing and silicified lacustrine sediments, hydrothermal Au-Ag and Pb-Zn veins, and Hg stockwerks.

–sinistral movement took place right after the formation of the NW–SE directed map-scale syncline ( Wein 1977 ; Fodor et al. 1994 ).
In contrast, the dextral transpressional motion suggested by model B can be fit into a stress field with NW–SE compression and
