Ko vēstī Ostlandes (1941-1944) laika ģeoloģiskā karte?
2020
2020. gada 27. janvārī LU Muzeja telpās Kronvalda bulvārī 4 notika pirmās Sarunas Muzejā, kuru centrālais objekts bija karte, kurā redzama ne vien Latvijas, bet arī plašu blakus esošo Krievijas teritoriju ģeoloģiskā uzbūve. Karti 1942. gadā, vācu okupācijas laikā, izdevis Zemes bagātību pētīšanas institūts. Sarunas bija pulcējušas ģeoloģijas jomu pārstāvjus, vēstures pētniekus un citus interesentus. Ģeoloģiskā karte digitalizētā formā ir pieejama LU e-resursu repozitorijā. Pasākums tika ierakstīts, lai tā gaitā pārcilātā informācija saglabātos kā LU Muzeja krājumā un būtu pieejams sabiedrībai. LU Muzeja direktore, Dr. paed. Iveta Gudakovska ievadā pastāstīja, ka sarunas iecerētas kā Muzeja …

A Dutch contribution to early interpretations of Meteor Crater, Arizona, USA – Marten Edsge Mulder’s ignored 1911 paper
2018
Abstract Following the first scientific descriptions in the late nineteenth century, the origin of the curious structure currently known as Meteor Crater (or Barringer Crater) in Arizona (USA) remained controversial until well into the twentieth century. Within the context of commercial mining, Daniel Moreau Barringer’s view that it recorded a substratum-penetrative meteorite impact (with the cosmic body still preserved) was commonly discarded. Marten Edsge Mulder (1847–1928), Dutch professor of medicine, found fault with Barringer’s non-explosive model. In 1911, Mulder advanced, in an ignored paper written in Dutch, a novel model of an explosive meteorite (‘meteor’ in Mulder’s terminology)…

Successes and failures in geodynamics
2001
Abstract The evolution of Earth models is reviewed and the open questions and problems are highlighted. Generally, evolution of science was not linear, but proceeded in “steps” of paradigms; where old ones remained within useful limits. “Geodynamic hypotheses”, while embedded into the general concepts of space and time, were often mutually exclusive and competing until the 1900s. Wegener's concept of continental drift was the first successful globally unifying view, but it was discarded by most Earth scientists. The “real” change of paradigms did not come before mid-century through geophysical observations in paleomagnetism, seismology, bathymetry, seafloor geology and dating, leading to th…
Análisis criptopaleontológico del lapidario de Teofrasto (s. III a.C.)
2013
The work “Perì líthon” or Teofrasto’s “Treatise of stones” has been considered the oldest text still available about minerals and rocks, even though it has remained incomplete. In this paper, the study of its contents shows that eleven of the stones called by geographic or cryptic names are either fossils from plants or vertebrates or chemical fossils. Therefore, the “Perì líthon” should also be considered as the oldest known treatise about palaeontology, because in addition to the fossils mentioned, it refers specifically to the fossilisation process.La obra “Perì líthon” o “Tratado de Piedras” de Teofrasto, es considerado el texto más antiguo conservado sobre minerales y rocas, aunque hay…
