Summary
| Description |
English: Travertine flowstone in a cave in Virginia, USA.
"Cave formations" in caves are technically called speleothem. Most speleothem is composed of travertine, a crystalline-textured chemical sedimentary rock composed of calcite (CaCO3). Travertine forms in most caves and at some springs by precipitation of crystals from water. Travertine speleothem occurs in a wide variety of forms. The most common variety of travertine speleothem is dripstone, which forms by the action of dripping water. The second-most common type of travertine speleothem is flowstone, which forms by precipitation of crystals from relatively thin films of flowing water. Flowstone typically has the appearance of a frozen waterfalls. Pure travertine is white. The colors seen in much of the travertine shown above are from iron oxides. Shenandoah Caverns is developed in structurally tilted carbonates of the Conococheague Formation (Upper Cambrian). The tilted bedding is quite evident in the flowstone geometry shown here. Locality: Shenandoah Caverns, Quicksburg, southern Shenandoah County, northern Virginia, USA |
