Jasper is an opaque rock of virtually any colour stemming from the mineral content of the original sediments or ash. Patterns arise during the consolidation process forming flow and depositional patterns in the original silica-rich sediment or volcanic ash .
Stone stripes on Catlow Rim in Oregon. A stone stripe, also called a lava stringer, [1] is an elongated concentration of mostly talus-like basalt rock found along a hillside or the base of a cliff. Many stone stripes occur without cliffs. A stone stripe is identified by its lack of vegetative cover.
Metamorphic rocks are formed by subjecting any rock type—sedimentary rock, igneous rock or another older metamorphic rock—to different temperature and pressure conditions than those in which the original rock was formed. This process is called metamorphism, meaning to "change in form". The result is a profound change in physical properties ...
Metamorphic rocks are created by rocks that have been transformed into another kind of rock, usually by some combination of heat, pressure, and chemical alteration. Sedimentary rocks are created by a variety of processes but usually involving deposition, grain by grain, layer by layer, in water or, in the case of terrestrial sediments, on land ...
The tall rocks seem to arise from the ground in a manner somewhat reminiscent of stalagmites, with many looking like petrified trees, thereby creating the illusion of a forest made of stone. Since 2007, two parts of the site, the Naigu Stone Forest ( 乃古石林 ) and Suogeyi Village ( 所各邑村 ), have been UNESCO World Heritage Sites as ...

Instead of metal, these wraps are primarily made of polypropylene fabric, paper and burlap. Fruit tree owners also employ this tactic as a preventive measure. Fruit trees can attract squirrels and ...
Slate – Metamorphic rock - A low grade metamorphic rock formed from shale or silt; Suevite – Rock consisting partly of melted material formed during an impact event – A rock formed by partial melting during a meteorite impact; Talc carbonate – A metamorphosed ultramafic rock with talc as an essential constituent; similar to a serpentinite
