Cathodoluminescence photos of different microbialite pattern. a Photomicrograph of the columnar stromatolites and interstitial sediments. Plane-polarized light; b Cathodoluminescence of the photo a, showing more luminescence in stromatolites than in interstitial sediments. Red crystals marked by the arrow are dolomites; c Photomicrograph of spotted clots and interstitial sediments. Plane-polarized light; d Cathodoluminescence of the photo c, showing more luminescence in spotted clots than in interstitial micrites; e Photomicrograph of digitate clots and interstitial sediments. Plane-polarized light; f Cathodoluminescence of photo e, showing more luminescence in digitate clots than in surroundings
