Also he devoted himself to geological mapping, one of the authors of the geological map of the country on the scale 1:500,000, published in 1899, which came to replace the one that had been published in 1876 by Carlos Ribeiro and Delgado. He played an important role in the elaboration of this letter, one of the best works of Portuguese geological cartography, collaborating intensely with Nery Delgado, the military engineer who at the time chaired the Geological Commission and headed the Geological Works Section. The cartographic studies he then carried out allowed him to publish a tectonic chart and a hypsometric chart of Portuguese territory. In the memory accompanying the hypsometric chart includes a set of studies on the physical geography of the Portuguese territory, still considered relevant today. In addition to the works of Portuguese theme, in the period prior to his coming to Portugal, he published several works concerning the paleontology and stratigraphy of the French and Swiss Jurassic lands, among which are worth mentioning the works that make up the work Esquisse du callovien et de The Oxfordien of the Middle Jura: Suivie of a Supplementary Aid to the Acanthicus Ammonites of the Occidental Jura, originally published in volumes III and IV of the Annals of the Geological Society of France.Bibliographic Metadata na Zentralbibliothek Zürich.Texto integral da obra.
