| 説明 | The large, columnar structures in this outcrop are thrombolites. Thrombolites are similar to stromatolites, in that they are bacterial buildups. Internally, stromatolites are thinly laminated. Thrombolites have a clotted internal texture.Stratigraphy: thrombolite bioherm at the top of the Wirrealpa Limestone, upper Lower CambrianLocality: creek cut along eastern side of access road to Old Wirrealpa Mine, ~200 meters north of the Blinman-Wirrealpa Road, Flinders Ranges, South Australia |
