Simulation of rock salt dissolution and its impact on land subsidence [PDF]

open access: yes, 2013
Extensive land subsidence can occur due to subsurface dissolution of evaporites such as halite and gypsum. This paper explores techniques to simulate the salt dissolution forming an intrastratal karst, which is embedded in a sequence of carbonates, marls,

Evaluation of Groundwater Recharge Estimates in a Partially Metamorphosed Sedimentary Basin in a Tropical Environment: Application of Natural Tracers

open access: yesThe Scientific World Journal, 2014
This study tests the representativeness of groundwater recharge estimates through the chloride mass balance (CMB) method in a tropical environment. The representativeness of recharge estimates using this methodology is tested using evaporation estimates ...

Development of a geological model useful for the study of the natural hazards in urban environments. An example from the eastern sector of Rome (Italy) [PDF]

open access: yes, 2015
Detailed knowledge of the subsoil setting is an extremely important issue for a correct risk reduction policy, especially when dealing with urban areas hosting cultural heritage, which enhance risk conditions even at low geo-hazard levels, as in the case

Application of an improved global-scale groundwater model for water table estimation across New Zealand [PDF]

open access: yesHydrology and Earth System Sciences, 2018
Many studies underline the importance of groundwater assessment at the larger, i.e. global, scale. The groundwater models used for these assessments are dedicated to the global scale and therefore not often applied for studies in smaller areas, e.g ...

The geology of the Strumble Head - Fishguard region, Dyfed, Wales [PDF]

open access: yes, 1979
An investigation was undertaken on the volcanic and volcaniclastic rocks forming the Fishguard Volcanic Group of Lower Ordovician age, which crop out in the Strumble Head - Fishguard area of Southwest Dyfed (North Pembrokeshire).\ud The nature of the lavas and volcaniclastic rocks suggests that this episode of vulcanicity was entirely subaqueous in ...

Preliminary experimental results by the prototype of Sanya Incoherent Scatter Radar

open access: yesEarth and Planetary Physics, 2020
In the past decades, the Incoherent Scatter Radar (ISR) has been demonstrated to be one of the most powerful instruments for ionosphere monitoring. The Institute of Geology and Geophysics at the Chinese Academy of Sciences was founded to build a state-of-

Application of palynological data to the chronology of the Palaeogene lava fields of the British Province: implications for magmatic stratigraphy [PDF]

open access: yes, 1997
New high-precision ages, determined from palynomorph assemblages within intercalated sedimentary deposits, are presented for the Palaeogene lava fields (Skye, Mull and Antrim) of the British Province. These data reveal very rapid averaged eruption rates (
