Organic geochemistry and mineralogy suggest anthropogenic impact in speleothem ...
Miller, A; Jimenez-Morillo, N; Coutinho, M; Gazquez, F; Palma, V; Sauro, F; Pereira, M; Rull, F; Toulkeridis, T; Caldeira, A T; Forti, P; Calaforra, JThe network of lava tubes is one of the most unexploited natural wonders of the Galapagos Islands. Here, we provide the first morphological, mineralogical, and biogeochemical assessment of speleothems fromvolcanic caves of the Galapagos to understand their structure, composition, and origin, as well as to identify organic molecules preserved in speleothems. Mineralogical analyses revealed that moonmilk and cora...

Miller, A Z; García-Sánchez, A; Coutinho, M; Pereira, M; Gázquez, F; Calaforra, J; Forti, P; Martínez-Frías, J; Toulkeridis, T; Caldeira, A TeresaThe Galapagos Islands (Ecuador) have a unique ecosystem on Earth due to their outstanding biodiversity and geological features. This also extends to their subterranean heritage, such as volcanic caves, with plenty of secondary mineral deposits, including coralloid-type speleothems and moonmilk deposits. In this study, the bacterial communities associated with speleothems from two lava tubes of Santa Cruz Island...
