Connecting molecular biomarkers, mineralogical composition, and microbial diver...
Palma, V; González-Pimentel, J; Jimenez-Morillo, N; Sauro, F; Gutiérrez-Patricio, S; De la Rosa, JM; Tomasi, I; Massironi, M; Onac, B; Tiago, ILanzarote (Canary Islands, Spain) is one of the best terrestrial analogs to Martian volcanology. Particularly, Lanzarote lava tubes may offer access to recognizably preserved chemical and morphological biosignatures valuable for astrobiology. By combining microbiological, mineralogical, and organic geochemistry tools, an indepth characterization of speleothems and associated microbial communities in lava tubes ...
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...
