Abstract The depositional environment of Gumai formation is still challenging to be studied. Previous studies the in Formation show a debate interpretation transition, shallow marine, and deep marine environment. study's objectives are identify lithology characteristics Baturaja region determine potential Formation. Miocene clastic sedimentary rocks well-preserved features Simpang Muara Dua, So...

The singular events which occurred at the initiation of the Flood should have produced a geologic signature with at least five characteristics: (a) a mechanical-erosional discontinuity (ED) identified by regional structural analysis—probably the most significant unconformity in any given area; (b) a time or age discontinuity (AD) identified by coarse sediments above the erosional unconformity c...

Introduction: At the 26-km-diameter Ries impact structure (Germany) suevite occurs in three different geological settings [1]: (1) a thick continuous layer in the central crater cavity inside the inner ring (" crater suevite " = CS), (2) thin isolated patches on top of the continuous ejecta blanket (" outer suevite " = OS), and (3) dikes in the crater basement and in displaced megablocks. In th...

the sorkh shale formation (lower triassic) crops out in parts of tabas block. this formation is composed of limestone, dolomite, sandstone, shale and gypsum. its lower contact with the permian rocks and its upper contact with the shotori formation is marked by distinct erosional unconformity. to determine the depositional environments of the sorkh shale formation, stratigraphic sections of goda...

Abstract ––A large regional-scale Ordovician continental basin has been revealed for the first time in Siberia. Sedimentary structures rocks of Tyva represent deposition environments rivers, oxbow lakes, dunes, river deltas, tidal, and coastal plains. Ichnofossils record a succession from freshwater (limnic-fluvial) to deltaic tidal facies. Integrated studies sedimentary Central show that they ...

The El'gygytgyn impact structure in Chukutka, Arctic Russia, is the only impact crater currently known on Earth that was formed in mostly acid volcanic rocks (mainly of rhyolitic, with some andesitic and dacitic, compositions). In addition, because of its depth, it has provided an excellent sediment trap that records paleoclimatic information for the 3.6 Myr since its formation. For these two m...
