Ni-rich mineral nepouite explains the exceptional green color of speleothems Martin Vlieghe, Gaëtan Rochez, Stéphane Pire-Stevenne, Jean-Yves Storme, Augustin Dekoninck, Yves Vanbrabant, Olivier Namur, Yishen Zhang, Alicia Van Ham-Meert, JeanPierre Donnadieu, Michel Berbigé, Jean-Luc Hasbroucq & Johan Yans Abstract:Speleothems are secondary mineral structures typically found in karstic caves and usually composed of calcite or aragonite. Despite being naturally white, some might exhibit unusual colors, such as blue, black, red, yellow or green.

The impact of background water flow on the early migration of a CO2 plume in a tilted aquifer during the post-injection period Mawda Awag*, Eric Mackay, Saeed Ghanbari *Institute of GeoEnergy Engineering, Heriot-Watt University, Edinburgh EH14 4AS, United Kingdom  Abstract: The study presents a numerical modelling analysis on CO2 plume migration in a dipping storage aquifer with background flux, which incorporates residual and dissolution trapping of CO2.

APPROACHES TO MONITORING AND REGULATION OF AN AQUIFER STORAGE AND RECOVERY SYSTEM IN THE EDWARDS AQUIFER, SOUTH-CENTRAL TEXAS, USA Jennifer R. Adkins Schudrowitz, Alyssa B. Balzen , F. Paul Bertetti AbstractThe Edwards (Balcones Fault Zone) Aquifer (Edwards BFZA) is a major karstic limestone aquifer in south-central Texas, USA. The aquifer serves as the primary water supply for approximately 2.5 million people and is integral to the ecosystems of major springs that are home to several threatened and endangered species.

GEOLOGY AS A PART OF A COLLEGE CURRICULUMH. S. Williams, 1892 The demand for scientific studies as a part of the college curriculum is felt by all those who have to do with the provision of higher instruction for American youth. The reasons for this may be various, but a fundamental reason is found in the tendency among the American people in particular, and in this age in general, toward practicality in all things.
