Boris Choubert: Unrecognized visionary geologist, pioneer of the global tectonics

摘要: This work is a review of Boris Choubert’s paper (1935), which was published in French underthe rather devalorizing title: “Research on the Genesis Palaeozoic and Precambrian Belts.” Despite itsinnovative content, this article had no impact either at time its publication or even later. It begins withthe construction remarkable fit circum-Atlantic continents. based 1.000 metersisobath instead shoreline. Thirty years before Bullard et al. (1965), it demonstrated an indisputableway reality continents motion surface Earth. Therefore, Choubert designatedWegener’s “continental drift” as main cause tectonics. Even going beyond Wegener’s theory, heargued that mechanism efficient well formation Triassic Pangaea, during wholePalaeozoic to result building Caledonian Hercynian mountains. Although he stillencumbered by vocabulary regarding geosynclines, described tectonics basedon horizontal mobility continental blocks.
