L ittle evokes a sense of wonder about the past like moments frozen in time: the contorted bodies of Pompeii’s horrified citizens fixed in their final poses, the footprints of an ancient hominin family cemented on an African savanna, the tracks of a Jurassic predator closing in on unsuspecting prey along a muddy riverbank, or tree stumps from an ancient Carboniferous rainforest buried in place ...

We grouped the fossil records of marine animal genera into suites defined by function and physiology. The stratigraphic coherence of the resulting diversity history indicates the importance of ecological structure in constraining taxonomic richness through time. The proportional representation of major functional groups was stably maintained for intervals as long as 200 million years, despite e...

Many of the veins enclosed within the Paleozoic basement of the Catalonian Coastal Ranges show severa1 common characteristics: low temperature of formation (between 75 and 200°C), the presence of complex polisaline fluids and a certain relationship to the pretriassic paleosurface. Mineralogical composition and age are variable, ranging from Pb-Zn veins with carbonate gangue of late Hercynian ag...

This study examines the use of the geographic information systems (GIS) in structural geomorphology to build the model of the crust based on fractal analysis of relief. Fractal theory, developed by B. Mandelbrot, used to determination morpho-bloc divisibility of the Earth’s surface. There is the traceable statistically recurring relief structure indicate the appropriate tiered hierarchy of crus...

the main purpose of this research paper is to compare qiujiahe formation (є1q) and longmaxi formation (s1ln) in north sichuan basin where shale gas exploration has not been fully researched, and hence represents the possibility of shale gas concentration under the complex geological conditions. based on valid laboratorial analysis, there are optimistic prospects for є1q and s1ln of research are...

The upper Paleozoic–lower Mesozoic strata in the northeastern Galilee Basin are important for their hydrocarbon and groundwater potential; however, despite numerous previous investigations, nat...

An exotic block of garnet-bearing schist has been found at the boundary between Early Triassic Takinosawa Unit Nedamo Belt and Jurassic Nakatsugawa Complex North Kitakami Belt, NE Japan. This is only second discovery schists in Belt; previously identified occur early Carboniferous Tsunatori units Belt. The characterized by a mineral assemblage garnet + phengite epidote albite quartz titanite. P...

late neoproterozoic-early cambrian schists have been occurred in southwest of zanjan city from the soltanieh belt. the soltanieh belt in northwest of iran is uplifted basement of precambrian-paleozoic in main central iran zone and includes outcrops of precambrian, paleozoic and mesozoic formations. late neoproterozoic-early cambrian schists, the oldest stratigraphy unit in the region, consist o...

The tectonic setting of South China during the late Paleozoic is essential to understanding geodynamics off eastern margin Pangea supercontinent due its unique paleo-position at confluence Paleo-Tethys and Panthalassic oceans. Limited magmatic matemorphic records in have hampered resolution this setting. Here, we present integrated biostratigraphic, geochronological, isotope geochemical data on...
