Rock fabric heterogeneity and its influence on the petrophysical properties of a building limestone: Lede stone (Belgium) as an example

International audience ; Lede stone is an important historical stone in Belgium, with many ceased and disappeared historical quarries. Owing to its geological nature, this stone exhibits considerable variation in petrophysical properties. Three macroscopical different facies from the solely remaining quarry area in Balegem (Belgium) were profoundly characterized for their pore network properties and petrophysical properties. The pore network was exhaustively studied combining water imbibition under vacuum, mercury intrusion porosimetry and X-ray computed microtomography. The three facies not o... Mehr ...
