Linking mineralisation process and sedimentary product in terrestrial carbonates using a solution thermodynamic approach [PDF]
, 2014 Determining the processes which generate terrestrial carbonate deposits (tufas, travertines and to a lesser extent associated chemical sediments such as calcretes and speleothems) is a long-standing problem.

The Budakalász Travertine Production
ASMOSIA XI, Interdisciplinary Studies on Ancient Stone, Proceedings of the XI International Conference of ASMOSIA, 2018 The stone monuments from the Roman towns along the Danube include a wide range of sepulchral, votive and architectural pieces made of the travertine quarried in the Buda Hills. The representative quarries of this rock are located at Budakalász, on the slope of the Monalovác Hill north of Aquincum, and in the Kápolna Hills (north of Budapest), while ...
