Three-dimensional images of a sample of Jhuran sandstone at 20× magnification by X-ray microscopy. The main phases present are segmented on the basis of intensity differences. The distribution of each of these phases are shown. a Heavy minerals (dark green); b Light green shades indicating carbonate cements; c Heavy minerals, carbonate cement and framework grains (pink) with prominent boundaries; d Heavy minerals (black arrow), carbonate cement (yellow arrow), framework grains (blue arrow) and zeolite cement (reddish brown shade, white arrow)
