Abstract
The term trovants was introduced for the first time by the Romanian geologist Gheorghe Murgoci more than one hundred years ago [1], and refers to concretionary sandstone formations. They are believed to form as a result of the fusion of layers of sand in the presence of high-concentrated calcareous water. The trovant geological reservation at Costes, ti, Romania, hold a large and diverse in size and shape collection of trovants embedded in alluvial strata. A new 3D images of a smallsize cm size trovant (a) were acquired using a Carl Zeiss Xradia Versa-510 X–ray µCT at LUMIR Laboratory. In the images (28.5 µm/voxel resolution) featured in our main graphic, we revealed the presence of subspherical structures built around a central nucleus represented by a full shell (b). We apply a binarization filtering technique for a cubic 600×600×200µm voxel sub volume (c), and show the presence of an interconnected porous (φ = 5-9 %) assembly, which provides main permeability fiuid-paths that control trovants formation through mineral precipitation around the inner shell structures (d). All images and simulations are acquired/performed using Avizo 2020.2 software.
