Abstract Generative potential and thermal maturity for Upper Palaeozoic source rocks from the south-eastern edge of Precaspian Basin were determined using Rock–Eval. A high hydrocarbon rock generative degree Lower Permian, Mid-Carboniferous strata have been revealed based on 39 samples. TOC values 0.4–5.5% obtained mature rocks. Integrated geochemical analysis Rock–Eval studies combined with 1D...

Abstract Using goof as water storage space plays a vital role in the ecological environment and economic development of arid mining areas, while rock strength stability coal pillars underground reservoirs are closely related to creep process. In this work, triaxial creep-seepage tests were conducted for samples develop new insights into behavior permeability evolution. The results showed that d...

High-resolution seismic reflections were used to map the upper 200 m along an approximately 22 km stretch of U.S. 50 highway in Reno County, Kansas, where natural and anthropogenic salt dissolution is known to threaten ground stability. Surface subsidence in this part of Kansas can range from gradual (an inch per year) to catastrophic (tens of feet per second), representing a significant risk t...

mechanism and factors influencing on creep behavior of clay soil have not been understood yet due to its complex structure. in this paper, to investigate the affecting parameters on the creep behavior of the clay soils such as stress level, over consolidated pressure and water pressure, odeometr test are performed in states of single stage, stepwise and overloaded-unloaded and the creep mechani...

The most difficult challenge that can be encountered when drilling a salt section is the difficulty of controlling change in fluid properties. In addition, challenging geological environment was encountered. , creep behavior, slim hole formation have few traits: high soluble, wash out (1). treatment did by using mud inhibits changes and resistant to contaminants. Sodium chloride potassium brine...

S U M M A R Y Many unresolved questions in geodynamics revolve around the physical behaviour of the two-phase system of a silicate melt percolating through and interacting with a tectonically deforming host rock. Well-accepted equations exist to describe the physics of such systems and several previous studies have successfully implemented various forms of these equations in numerical models. T...

materials exhibit significant creep behavior at temperatures above 40% of their absolute melt temperature. lead, tin and their alloys are such materials which experience significant creep behavior in room temperature. one of the most important applications of the tin-lead alloys is soldering electronic circuits in electronic industry, and for lead are isolation walls and wet batteries. room tem...

Reactions in the Earth's crust occur through a dissolution-precipitation process presence of fluid. Dissolution releases aqueous species which are transported to locus precipitation. This replacement generates creep deformation (i.e., creep) due volume change during reaction and stress-controlled mass re-distribution rock. Reaction under stress also modifies rock microstructure pressure record ...

Massive deposits of rock salt are mined in the Salt Range area Pakistan. The main export products include lamps, blocks, and tiles, while local consumption includes chemical industry domestic use. profitable production for value addition depends on quality, size, shape block. processing is easier when very few cracks present blocks. current mining practice involves drilling blasting, which intr...
