This paper presents our work on development of OWL-driven systems for formal representation and reasoning about terminological knowledge and facts in petrology. The long-term aim of our project is to provide solid foundations for a large-scale integration of various kinds of knowledge, including basic terms, rock classification algorithms, findings and reports. We describe three steps we have t...

The most volcanically active regions of our planet are concentrated along the axes of the globe, encircling midocean ridges. These undersea mountain ranges, and most of the oceanic crust, result from the complex interplay between magmatic (i.e., eruptions of lavas on the surface and intrusion of magma at depth) and tectonic (i.e., faulting, thrusting, and rifting of the solid portions of the ou...

High-silica topaz-bearing rhyolites of Cenozoic emplaced as domes, lava flows or shallow intrusions. They age are widely distributed across the western USA and may also contain Fe-Mn garnet, beryl, bixbyite, pseudoMexico. They are characteristically enriched in fluorine brookite, hematite and fluorite in miarolitic cavities or with(>0.2 wt.%) and incompatible lithophile elements (e.g. Li, in th...

The Proto-Tethys Ocean existed from the Neoproterozoic through early Paleozoic during breakup of Rodinia and was closed with subduction accretion numerous East Asian blocks. North Qinling Orogenic Belt is thought to have formed upon closure Kuanping between China Craton Block. However, timing this widely debated Paleozoic. To date, controversy remains as a barrier in understanding ocean-contine...
