University of Cagliari, Department of Civil and Environmental Engineering and Architecture, Via Marengo 2, 09123 Cagliari, ItalyJournal of African Earth Sciences (Impact Factor: 1.38). 12/2013; 99. DOI: 10.1016/j.jafrearsci.2013.11.020
The geology of the central part of Ethiopia exhibits a variety of rock types that can potentially be developed for construction stone production, of which the most wide spread and important one is the Termaber basalt. Even though some preliminary work is done on these rocks towards construction material application, it remains largely that this resource is untouched and needs further scientific characterization for the use in large scale industrial application. Basaltic rocks have been widely used in many parts of the world as concrete aggregate and dimension stone for various civil structures. The present research study was carried out for Geo-engineering evaluation of Termaber basalt rock mass for crushed stone aggregate and building stone from Central Ethiopia (around Debre Birhan).

ABSTRACT: This review describes advances in the XRF group of techniques published approximately between April 2014 and March 2015 and is therefore restricted to a selection of papers featuring developments in the XRF armoury. An active topic during this review period was that of imaging techniques and, more particularly of micro X-ray fluorescence spectrometry. Silicon-based semiconductor X-ray detectors such as SDD and Si(PIN) continue to reflect the maturity and widespread routine use of such devices. The significant expansion in studies evaluating the field use of portable XRF instrumentation in geological applications, often still proving the quality of the data, rather than adopting the technique in routine applications. New synchrotron beamlines offer previously unavailable spatial resolution and throughput for the characterisation of advanced energy materials and devices under varying temperatures and gas atmospheres. Nano-materials feature extensively this year such as the use of nanoparticles in cancer imaging and therapy. Synchrotron radiation has become a preferred technique for the analysis of a wide range of archeological samples, artwork, museum specimens and environmental studies. There has been a substantial rise in the number of Chinese researchers investigating objects of cultural heritage, especially porcelain, glazes and glass. Advances in TXRF and related techniques continue to feature with studies on thin films and nanomaterials.
