Carbonatación de diatomeas y génesis de calizas/dolomías diagenéticas en ambiente continental y marino (Mioceno de Tresjuncos, Cuenca y Níjar, Almería). Un ejemplo de secuestro de CO<sub>2</sub> en la Naturaleza

Abstract: En el presente trabajo se estudian los procesos de carbonatación de frústulas de diatomeas y la consecuente formación de calizas/dolomías diagenéticas, en estratos de diatomitas marinas (Messiniense, sección de Níjar) y lacustres (Turoliense, sección de Tresjuncos). Se realiza un estudio mineralógico y petrológico para conocer el reemplazo de ópalo A por calcita o dolomita, considerando los factores que favorecen este reemplazo en ambos ambientes. Los datos obtenidos son relevantes para la investigació… Show more

“…IV. DISCUSSION Based only on the macroscopic description of the lithic artefacts from level IIIb of the Teixones cave, it is possible to identify certain elements, such as the presence of bioclasts or evaporitic relicts or carbonates, which reveal the nature of the bedrock in which the chert nodules were formed [13][14] [15]. On this basis, different strategies can be used to locate the formations from which the different types of cherts come.…”

“…The macroscopic and microscopic descriptions of the lithic artifacts from sub-unit IIIb of Teixoneres Cave make it possible to identify certain elements (e.g., the presence of bioclasts, evaporitic relicts, or carbonates) that reveal the nature of the bedrock in which the chert nodules were formed [25], [27], [28]. This information allows the use of different strategies to locate the provenance of the different types of cherts.…”
