Web________ can produce intricately folded rocks. differential stress Which agent of metamorphism was primarily responsible for generating the rock in the image above? heat Which kind of stress (confining pressure or differential stress) is responsible for creating the texture visible in this rock? differential stress WebGneiss -Foliated -medium to coarse grained -highest grade -parent rock: shale, granite, and volcanic rocks Migmatite If gneiss begins to melt but solidifies again, you get a mixture of igneous and metamorphic rock non foliated have no foliation (layers) -formed without compression or shear -hornfels, quartzite, and marble Hornfels metamorphic rock

WebCan parent rock features such as sedimentary structures and fossils survive low-grade metamorphism? A)Yes, because the shells of the organisms are strong enough to withstand directed pressure. ... _____ can produce intricately folded rocks. A)Differential stress B)Confining pressure C)Heat D)Hydrothermal fluids E)Cold surface water. Q32: WebRocks begin to partially melt when they reach a combination of sufficiently high temperatures (> 650°C) and pressures (>34MPa). Some rocks have compositions that produce more melt than others at a given temperature, a rock property called fertility. litebow texture pack

WebSep 11, 2024 · Folds are geologic structures created by plastic deformation of the Earth’s crust. To understand how folds are generated, take a piece of paper and hold it up with a hand on each end. Apply compressional forces (push the ends towards each other). You have just created a fold (bent rock layers). Depending on how your paper moved, … WebA) Yes, because the shells of the organisms are strong enough to withstand directed pressure.B) No, because the sediments and organic materials will be melted. C) Yes, because such features can withstand low temperatures and pressures but will be destroyed in higher metamorphic grades. WebYes, because such features can withstand low temperatures and pressures but will be destroyed in higher metamorphic grades. 5. ________ can produce intricately folded rocks. Differential stress 6. Generally speaking, how does the chemical composition of most metamorphic rocks compare to that of the parent rock? liteboxer boston
