Pleistocene climate changes were major historical events that impacted South American biodiversity. Although the effects of such changes are well-documented for several biomes, it is poorly known how these climate shifts affected the biodiversity of the Pantanal floodplain. Fish are one of the most diverse groups in the Pantanal floodplains and can be taken as a suitable biological model for re...

Continental carbonates, such as travertines and tufas, formed from CO 2 -rich groundwater degassing it emerges at the Earth’s surface, are often associated with major crustal-scale faults. The Carraclaca site, in Lorca-Totana section of Alhama de Murcia Fault, Spain, presents a complex geomorphological landscape controlled by active tectonics. geology here records interaction between Quaternary...

As part of the European ACT-sponsored research consortium, DETECT, we developed an integrated characterisation and risk assessment toolkit for natural fault/fracture pathways. In this paper, describe DETECT experimental-modelling workflow, which aims to be predictive fault-related leakage quantification, its application a field case example validation. The workflow combines laboratory experimen...

Banded travertines are important parts of fissure ridge systems, but studies on geochemical characterization banded limited. This study investigated the lithofacies and stable carbon oxygen isotopic features from Xiagei (southwestern China) to examine their formation mechanisms. Petrographic analyses revealed two lithotypes: thick-laminated palisade crystalline crust thin-laminated composite cr...

Alteration of mantle peridotite in the Samail ophiolite forms secondary minerals, mainly serpentine and Mg-rich carbonates. Magnesium accounts for ?25 – 30% mass its mobility can be used to trace this alteration. We report first set Mg isotope measurements from peridotites their alteration products Oman. Partially serpentinized have ratios that are indistinguishable estimates average bulk silic...

Objective. Analyze the structure and features of nature reserve fund within western part North Pokut highland find out problems prospects for its optimization. Methods. Field, analysis, processing stock materials environmental services, remote sensing methods, cartographic. Result. The Pokuttya forms one regional landscape park, 15 reserves, 37 natural monuments, 12 protected tracts, three arbo...

Banded Ca-carbonate veins in travertine deposits are efficient recorders of the compositional fluctuations geothermal fluids flowing (or flowed) from deep reservoirs up to surface, within fault zones. In this view, these represent key tools for decoding those factors that influenced geochemical variations. We have analyzed developed fractures channeling forming deposits. The studied cut a fossi...
