High resolution X-ray computed tomography (HRXCT) has been barely used in speleothem science. This technique has been used to study a Holocene stalagmite from Praileaitz Cave (Northern Spain) to evaluate its potential for petrologic studies. Results were compared with those derived from the routine procedures and a very good correlation was found. Our work indicates that HRXCT can be considered as a useful tool for a rapid and non-destructive characterization of the speleothem, providing…

Non-destructive, high-resolution X-ray micro-CT of a Hairy Stalagmite: investigating the structural details of a biogenic speleothem

Three-dimensional X-ray micro-computed tomography permits to investigate the internal structure of objects at a high resolution without altering its original form. It also facilitates the rendering

Stalagmites from western Thailand: preliminary investigations and challenges for palaeoenvironmental research

Locating suitable caves and stalagmites for palaeoenvironmental and palaeoclimatic studies can be challenging. Isotopic geochemical analyses, albeit commonly performed for palaeoclimatic

Integration of Geological, Mineralogical and Geochemical Methods in the Characterization of El Nitro and Las Alsacias Caves, Zapatoca (Colombia)

The present study integrates geological, mineralogical and geochemical methods in the characterization of the caves: El Nitro and Las Alsacias, from Zapatoca (Colombia). With lithologies dating from

Primary characteristics of selected stalagmites from four caves located between Erdemli and Silifke (Mersin), southern Turkey—implications on their formation

This study describes the primary chacteristics of the selected stalagmites from the four caves in southern Turkey and interprets their formation via petrographic, SEM–EDX, XRD, ICP–AES and stable

Ancient maya stone tools and ritual use of deep valley rockshelter, Belize

This paper discusses the technological and microscopic use-wear analyses of the chert debitage excavated from Deep Valley Rockshelter. This rockshelter, located in the Caves Branch River Valley of

Review of Laboratory Scale Models of Karst Aquifers: Approaches, Similitude, and Requirements

This review attempts to classify, and introduce a framework for constructing a karst aquifer physical model that is more representative of field conditions, and separates LSMs into four groups: sand box, rock block, pipe/fracture network, and pipe-matrix coupling.

Hydroclimate variability of western Thailand during the last 1400 years

<p>Mainland Southeast Asia is located on the route of moisture transport of the Indian summer monsoon where hydroclimate records from speleothems have rarely been investigated. Here we present a



Applications of X-ray computed tomography in the geosciences

Abstract X-ray computed tomography (CT) is a non-destructive technique with wide applications in various geological disciplines. It reveals the internal structure of objects, determined by variations

Application of high-resolution X-ray computed tomography in determining the suitability of speleothems for use in paleoclimatic, paleohydrologic reconstructions

The use of isotopic and trace element compositions of speleothems (i.e., secondary cements found in caves such as flowstones, stalagmites, and stalactites), has grown with the increased interest in

Speleothem Science: From Process to Past Environments

Speleothems (mineral deposits that formed in caves) are currently giving us some of the most exciting insights into environments and climates during the Pleistocene ice ages and the subsequent

Open-system alpine speleothems; implications for U-series dating and paleoclimate reconstructions
