Introduction. The current hypothesis is that Martian sinkholes do not exist. It is proposed that the low pH environment resulting from the high CO2 content of the atmosphere will cause calcium carbonate to be deposited as calcite cemented sandstone rather than limestone [5]. Calcite, as well as gypsum, halite, smectite and illite, has been detected in Martian meteorites providing proof of the p...

A sedimentological investigation of Miocene deposits at the periphery Zagros foreland basin , Kurdistan Region, NE Iraq, reveals a cyclical arrangement carbonate-evaporite ramp facies . The study aims to provide rare insight into lateral variability microfacies and environments such systems' inner shoreline Between 10 40 depositional cycles are preserved, separated by flooding surface, recordin...

Evaporite mobilisation in evaporite-cored anticlines leads to topographic growth that can alter sedimentary routing shallow marine environments. This paper analyses two perpendicular the NW Africa coast understand how their tectonic evolution influenced sediment pathways during Early Middle Jurassic and Cretaceous exhumation of Mesozoic margin hinterland. The Essaouira-Agadir Basin Morocco unde...

We present a comprehensive analysis of spatially resolved moderate spectral resolution near-infrared spectra obtained with the adaptive optics system at the Keck Observatory. We identify three compositionally distinct end member regions: the trailing hemisphere bullseye, the leading hemisphere upper latitudes, and a third component associated with leading hemisphere chaos units. We interpret th...

A high density of local natural and human-induced ground deformation 11 structures resulting from the presence of evaporites occur extensively 12 around Zaragoza (NE Spain), posing risks to infrastructures, buildings and 13 agriculture. We studied the potential of a series of interferograms 14 constructed from 29 ERS -1/2 images to detect different types of ground 15 deformation related to evap...

Owens Lake, California, a saline terminal lake desiccated after diversion of its water source, was formerly the single largest anthropogenic source of fugitive dust in North America. Over 100 billion m 3 yr 1 of fresh water are projected to be used for mandated dust control in over 100 km of constructed basins required to be wetted to curtail emissions. An extensive evaporite deposit is located...

The Dongying Depression (Bohai Bay Basin, eastern China) was widely filled with evaporite (anhydrite and halite) layers during the Paleogene period, especially middle of fourth member Shahejie Formation (Es4). Most are interbedded mudstone strata. strata Es4 divided into three sections, referred to as upper layers, lower respectively. analysis elemental concentrations, ratios, Pr/Ph suggests th...

This study focuses on the economization of natural anhydrite, which has a wide range uses and is environmentally friendly, in Türkiye. Anhydrite, one most common evaporitic minerals world, almost no usage area Evaporite deposits consisting gypsum, halite, bassanite selenite are prominent country, especially Tertiary period sedimentary basins. The Sivas basin these important Mining operates carr...
