Pedogenesis and clay mineralogy of soils and rock samples were studied in a transect of calcareous, gypsiferous, saline soils and sediments of Bakhtegan lake bank in southern Iran. The main objectives of study were to determine the occurrence of clay minerals and factors controlling their distribution pattern and relative abundance in soils and parent materials. The soil parent material is high...

Introduction: The discovery of substantial evaporite deposits at the Opportunity rover landing site in Meridiani Planum on Mars argues for significant interactions between liquid water and local rocks during some stage of the Martian past. However, evaporites can form under a dazzling variety of water/rock ratios, from long-term evaporation of expansive reservoirs to periodic recycling of water...

productivity of an oil well is an important parameter in any oil field development. low production rate of the wells, impose more production wells drilling which directly jeopardizes the economical feasibility of the project. oil production rate in some of the wells is very low due to low permeability of the reservoir rock. several practice like hydraulic fracturing and acid fracturing is very ...

Strong evidence for evaporitic sulfate minerals such as gypsum and jarosite has recently been found on Mars. Although organic molecules are often codeposited with terrestrial evaporitic minerals, there have been no systematic investigations of organic components in sulfate minerals. We report here the detection of organic material, including amino acids and their amine degradation products, in ...

CO2 Storage in Saline Aquifers — Saline aquifers represent a promising way for CO2 sequestration. Storage capacities of saline aquifers are very important around the world. The Sleipner site in the North Sea is currently the single case world-wide of CO2 storage in a saline aquifer. A general review is given on the specific risks for CO2 storage in saline aquifer. The regional distribution of C...

The Industrial Revolution has led to a substantial i ncrease in the generation and release of greenhouse gases (GHG) into environment. These GHGs like CO2 if present in abundance in the atmosphere cause damage to the natural ecosystems through global warming. One of the possible approaches to mitigate the global warming phenomena is by safely and long-term underground disposal of CO2 in suitabl...

In geodynamically active areas, spatio-temporal variations in rock uplift can provide key insights into the processes responsible for evolution of topography. The Central Anatolian Plateau (CAP) southern margin experienced a rapid rock-uplift pulse with maximum rates 3.5 m/kyr during Quaternary, based on marine sediments dated to middle Pleistocene that are now located at 1,500 m.a.s.l. Fluvial...

The territory of Albania presents wide outcrops soluble rocks, with typical karst landforms and the presence remarkable carbonate aquifers. Many areas are located near coasts, which results in a variety environmental problems, mostly related to marine intrusion. This paper focuses on brackish springs Albania, exhibit temperatures approximately equal yearly air temperature at their location. Tot...
