Description	micro-XRCT data set (projections and reconstructed images) of a Carrara marble core with a diameter of 5 mm. The sample was extracted with a water-cooled diamond drill from a bigger sample with a diameter of 30 mm and a length of 80 mm which was before subjected to following thermal treatment to initiate cracks: Starting at room temperature (20°C), the sample was heated up with a rate of 3 K/min to 600°C. After a holding time of 2 hours at 600°C, the sample was subsequently slowly cooled down in the closed oven back to room temperature (20°C).
