Slate Slate is a low grade metamorphic rock generally formed by the metamorphosis of mudstone / shale, or sometimes basalt, under relatively low pressure and temperature conditions.Clay minerals in the parent rock metamorphose into mica minerals ( biotote, chlorite, muscovite) which are aligned along foliation planes perpendicular to the direction of pressure. Definition. Granite. Hint: the parent rock shale can produce many different metamorphic rocks, but granite can only produce one of the metamorphic rocks on this list. Group of answer choices ( Quartzite Meta-conglomerate Serpentinite Anthracite Gneiss Amphibolite Slate Marble) Gneiss has the greatest degree of metamorphism in this group. Metamorphic rocks form from pre-existing rocks ("parent rocks") due to changes in either temperature, pressure, or volatiles within the earth, often by a combination of all three. What is the parent rock of schist? What is the parent rock of the metamorphic rock Quartzite? Marble is much harder than its parent rock. Sandstone is the parent rock of Quartzite. HW07: Metamorphic Rocks, Processes, and Resources Lab Activity 7.3 - The Parents of Metamorphic Rocks 2 of 6 Complete Review You will identify the potential parent rock(s) of five specified metamorphic rocks. This allows it to take a polish which makes it a good material for use as a building material, making sink tops, bathtubs, and a carving stone for artists. The specimen shown above is … It is the finest grained foliated metamorphic rock. Today, headstones are made from marble and granite because both of these rocks weather very slowly and carve well with sharp edges. Definition. Shale. In doing so, you will relate metamorphic rocks to other metamorphic rocks and to rocks belonging to the other two classes. Over time, slate may transition into other metamorphic rocks, such as phyllite or schist. Term. Gneiss is a medium to course grained metamorphic rock.. Shale is the typical parent rock. Shale: Term. Slate is a fine-grained, foliated metamorphic rock that is created by the alteration of shale or mudstone by low-grade regional metamorphism. Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is made up of clay minerals. Slate is a metamorphic rock with a dull luster.The most common color of slate is gray, but it can also be brown, green, purple, or blue.Slate is formed when a sedimentary rock (shale, mudstone, or basalt) is compressed. Shale can metamorphose into slate, phyllite, schist or gneiss depending on the degree of heat and pressure. The parent rock of slate is always sedimentary, and usually shale (mudstone). Term. The parent rock for schist is phyllite. You've likely encountered slate on a building or an old chalkboard. Definition. What parent rock is Slate from? The parent rock for slate is shale. What is the parent rock of Gneiss from? Slate is a low grade type of metamorphic rock. Definition. Gneiss has the greatest degree of metamorphism in this group a building an.
