Petrographical studies examining the development and variations of sub-solidus reactions recorded in the Toki granite represent the three-dimensional cooling pattern of this zoned pluton in Central Japan. Samples collected from 19 boreholes in the Toki granite show characteristics indicative of spatial variations in the extent of the sub-solidus reactions. Exsolution coarsening has produced mic...

Echinoderms have long been considered to be one of the animal phyla that is strictly marine. However, there is growing evidence that some recent species may live in either brackish or hypersaline environments. Surprisingly, discoveries of fossil echinoderms in non-(open)marine paleoenvironments are lacking. In Wojkowice Quarry (Southern Poland), sediments of lowermost part of the Middle Triassi...

Fossil deposits are among the most attractive geosites in nature parks and geoparks. The Register Cadastre of Bulgarian geological phenomena includes several outstanding fossil estimated as national significance. However, they assessed according to general methodology for evaluating all classes geosites: geomorphological, paleontological, petrographical, etc., so their specific characteristics ...
