To better understand the coupled thermo-hydro-mechanical processes in Callovo-Oxfordian (COx) claystone formations induced by heat emitting high-level radioactive waste, different scales of in-situ heater experiments have been conducted ANDRA Meuse/Haute-Marne Underground Research Laboratory (M/HM URL) at Bure France. In order to prove predictability numerical codes for a site-scale repository,...

Blocks 10 and 11.1 are located at the western boundary of Nam Con Son basin, offshore southern Vietnam. Hydrocarbon shows have been encountered in many wells as Gau Chua (GC), Ca Cho (CC), Ngua (GN), Phi Ma (PM), Than (TM), etc. In CC GN fields, oil gas were discovered Miocene sandstone reservoirs fractured granite basement. The Cau Dua formations active source rocks this area. Oil generated fr...

Floor heaving is a phenomenon that occurs in almost all mining roadways and tunnels. It can restrain the advance of heading face or cause serious problems during roadway use. The highest levels floor uplifting are observed coal mines, which reduce output even stop it altogether. intensity depends on rock type, stress mass, rocks’ mechanical properties. deformation develops when secondary state ...

The infrastructure project has many lies on the mudrock foundation. Some reports in Hambalang, West Java, Indonesia, state engineering problem related to landslides and foundation failure due material's existence. originated from Jatiluhur Formation. is also present slope stability, such as surface erosion landslide slopes. Landslide material easily broken into smaller fragments. This research ...

Nineteen ichnotaxa, together with algal and invertebrate remains, various pseudo-traces sedimentary structures are described from the Torneträsk Formation exposed near Lake Torneträsk, Lapland, Sweden, representing a marked increase in diversity of biotic traces recorded this unit. The “lower siltstone” interval contains mostly simple pascichnia, fodinichnia domichnia burrows trails low-energy ...

kamtal skarn is located 15 km northeast of kharvana, east-azarbaijan. a quartz-monzonitic stock of oligocene age intruded the upper cretaceous sedimentary sequence (claystone, limestone, marl, and siltstone) developing noticeable metamorphic (marble, hornfels) and metasomatic (skarn) alteration zones along the contact. kamtal skarn is of calcic type and consists of both endoskarn and exoskarn z...

the alborz coal basin is located in northern part of iran. the coal deposits of shahrood in eastern alborz, zirab in central alborz and abyek in western alborz were studied as typical coalfields of the basin. shemshak formation which is the main coal-bearing sequence was formed during the triassic-jurassic in the basin. it consists of sandstone, siltstone, shale and claystone, which variedly al...

Fine grained sedimentary rocks, both clastic and carbonate, are believed to be the most abundant rock type on the Earth‟s surface (Picard, 1971; Blatt, 1982). Fine grained rocks appear to constitute somewhere in the region of 70% (Holmes, 1937) and 80% (Clarke, 1924) of all the sediment ever produced. In sedimentology the size grade scale most commonly used is that which was introduced by Udden...

Abstract The conditions in ancient evaporative environments conducive to authigenic carbonate (especially dolomite [CaMg(CO 3 ) 2 ]) formation are still insufficiently understood. Insights from microfacies analysis can help constrain the these environments. We provide a brief overview of association and carbon oxygen isotope compositions beds intercalated claystone-rich succession Norian Arnsta...
