The behaviour of fossil organisms can typically be inferred only indirectly, but rare fossil finds can provide surprising insights. Here, we report from the Eocene Messel Pit Fossil Site between Darmstadt and Frankfurt, Germany numerous pairs of the fossil carettochelyid turtle Allaeochelys crassesculpta that represent for the first time among fossil vertebrates couples that perished during cop...

Many coal mines are being abandoned for economic and environmental reasons in China. The repurposing of open-pit into pumped storage hydropower (PSH) can help with the renewable energy, improve mine environments, provide added value. Construction PSH plant will change water level pit, which is envisaged as lower reservoir, thus influencing slope stability. In this study, Fushun West Open-Pit wa...

Constructing ponds to protect downstream ecosystems is a common practice in opencast coal mine reclamation. As these ponds remain integrated in the landscape, it is important to evaluate the extent of the effect of mine pollution on these ecosystems. However, this point has not been sufficiently addressed in the literature. The main objective of this work was to explore the metal pollution in m...

Very little is known about the organisms that are impacted by mine waste in the Berkeley Pit Lake System. However, it is known that if heterotrophic and autotrophic organisms are properly nutrified, they can bioremediate mine waste-influenced areas as a benefit of their physiological processes. However, before any type of bioremediation of an ecosystem can begin, it is essential to gain a funda...

Studies were conducted at the deepest location of the meromictic Piaseczno pit lake, southern Poland, which was created in abandoned sulphur opencast. Pearson correlation and PCA were used to established the relationship between the elements and physico-chemical parameters of the water, whereas discriminant test to study vertical and time differentiation of Cd, Pb, Sr, Cu, Zn, Mn, and Fe concen...

In Europe, 1132 Mt of sand and gravel were mined in 2019, which causes major changes to the hydrogeological cycle. Such may lead significantly raised or lowered groundwater levels. Therefore, aggregate sector has ensure that impacts on existing environmental water infrastructures are kept a minimum post-mining phase. risk assessments often made by empirical methods, based assumptions do not mee...

The research looks at the rotifer diversity in five different coal mine generated pit lakes from Raniganj Coal Field Area (RCF), West Bengal, India. collection methodology was involved monthly sampling (n = 120) to analyze using surface hauling with standard plankton net of mesh size 55 µm and water column depths (20 cm 50 cm) for periods two years (February 2018 – January 2020). Analyzes some ...
