No pumice is not a porphyritic igneous rock, a porphyritic rock is characterized by the presence of phenocrysts (large mineral grains) and very small mineral grains with none in between. This implies that there was two different stages of cooling. Pumice is an extrusive igneous rock that cooled very quickly.
What else can I help you with?
What is the metamorphic form of pumice?
The metamorphic form of pumice is known as "pumiceite." This form of metamorphic rock is created through intense heat and pressure acting on pumice, which causes it to recrystallize and change its mineral composition. Pumiceite typically has a more compact and dense structure compared to pumice.
Which of Slate Granite Shale or Pumice is classified as a sedimentary rock?
Slate, granite, and shale are classified as metamorphic or igneous rocks, while pumice is classified as an igneous rock. Sedimentary rocks are formed through the deposition and solidification of sediment.
Is pumice igneous rock metamorphic rock or sedimentary rock?
Pumice is an igneous rock formed from volcanic eruptions. It is created when lava with high gas and water content rapidly cools and solidifies, trapping bubbles of gas inside. This rapid cooling results in a porous rock with a low density, making pumice able to float on water.
Is a pumice rock a rock or a mineral?
A pumice rock is considered a rock because it is composed of multiple minerals, mainly feldspar and quartz. Minerals are the building blocks of rocks, so pumice is classified as a rock rather than a single mineral.
Is pumice foliated or non foliated?
Igneous rock (like pumice) does not normally display banding, layering, or flaky texture. Foliated vs. non-foliated as a descriptive term in rock identification is most often used in reference to metamorphic rock.
What metamorphic rock can float?
Pumice.
Is pumice a soft metamorphic rock?
Yes
Is the metamorphic rock obsidian or pumice?
Neither. Both pumice and obsidian are igneous.
What is a poro us metamorphic rock?
Travertine might be called porous. Pumice might be considered metamorphic.
What is the metamorphic form of pumice?

Which of Slate Granite Shale or Pumice is classified as a sedimentary rock?
Slate, granite, and shale are classified as metamorphic or igneous rocks, while pumice is classified as an igneous rock. Sedimentary rocks are formed through the deposition and solidification of sediment.
Why doesn't pumice or obsidian turn into a metamorphic rock?
Pumice and obsidian are both forms of volcanic glass, which weathers away fairly easily.
Can metamorphic rocks float?
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
Which medium-grade metamorphic rock is mostly composed of quartz mica chlorite talc hornblende?
pumice
What type of rock is granite pumiceand marble?
Granite is an intrusive igneous rock. Pumice is an extrusive igneous rock. while, Marble is a (non-folliated) metamorphic rock.
Is pumice igneous rock metamorphic rock or sedimentary rock?
Pumice is an igneous rock formed from volcanic eruptions. It is created when lava with high gas and water content rapidly cools and solidifies, trapping bubbles of gas inside. This rapid cooling results in a porous rock with a low density, making pumice able to float on water.
