Thanks in advance, I just need to know if these rocks are foliated or mon foliated the answers I need most are 3, 4, 6, 12, 1. Foliation in geology refers to repetitive layering in metamorphic rocks. The word comes from the Latin folium, meaning "leaf", and refers to the sheet-like planar structure. It is sometimes called greenstone, or greenschist if it is foliated. Phyllite 11. Amphibolite 2. Slate is another type of _____ (foliated or nonfoliated) metamorphic rock. Soapstone Slate: Slate is a beautiful grey to clay-looking rock that has a beautiful grainy texture to it. It is a type of foliated metamorphic rock that is produced by the metamorphism of shale. User: A calcium-rich nonfoliated rock that is often associated with economically valuable mineral deposits is _____.A. One common nonfoliated meta-morphic rock is marble, which develops from limestone. Serpentine marble 13. fine coarse 1 points QUESTION 41 Identify sample Q, noting the textural features you identified in previous questions. Foliated rocks have platy or elongate minerals aligned in roughly parallel planes or in wavy bands or planes. skarn B. marble C. phyllite D. quartzite User: Which of the following is a type of nonfoliated metamorphic rock? The original minerals within the rock recrystallize into larger sizes and the atoms become more tightly packed together, increasing the density of the rock. As the rocks become heated at depth in the Earth during regional metamorphism they become ductile, which means they are relatively soft even though they are still solid. Question: Is slate foliated or nonfoliated? The mineral chlorite gives it a green color. Phyllite is a foliated metamorphic rock that has been subjected to low levels of heat, pressure and chemical activity. Foliation is a texture that develops when enough minerals grow in a preferred orientation during moderate to high-grade metamorphism. Slates are predominantly realigned clay minerals. A. slate B. gneiss C. phyllite D. quartzite Weegy: The following is a non-foliated metamorphic rock: quartzite. Non-foliated metamorphic rocks such as hornfels, marble, quartzite, and novaculite do not have a layered or banded appearance. Slate. Each layer can be as thin as a sheet of paper, or over a meter in thickness. Graphite, chlorite, talc, mica, garnet and staurolite are distinctive metamorphic minerals. Is it fine-grained or coarse-grained? Non-Foliated: Cordierite, anthophyllite, muscovite, magnetite, chlorite, apatite and rutile: Close-up 1 • Skarn (Garnet-wollastonite skarn) Non-Foliated: Wollastonite, garnet, and diopside: Close-up 1 • Slate: Foliated - Slaty Cleavage: Sericite, chlorite, carbonate, and quartz: Close-up 1 • Slate (Andalusite slate) Foliated - Slaty Cleavage Examples of foliated rocks are slate, shale, and gneiss. Chlorite shist 3. How to use foliated in a sentence. Low grade: Metabasalt is metamorphosed basalt! Marble 9. Slate, phyllite, schist, gneiss 2. nonfoliated - a rock not exhibiting layers. Foliated Metamorphic Rock Examples: Schist Slate Phyllite. Non-foliated rocks form through recrystallization of single-mineral sedimentary rocks, usually those that have been touched by magma. Slate is a hard, fine-grained rock with a well-developed rock cleavage or slaty cleavage caused by the incipient growth of platy (micaceous) minerals, due to metamorphism of fine-grained clastic sediments such as shale and siltstone and also volcanic tuffs. Metamorphic rock is classified by texture and composition. This causes the minerals in the original rock to reorient themselves with the long and flat minerals aligning perpendicular to the greatest pressure direction.
