What is an example of porphyritic igneous rock?
Granite is an example of a porphyritic igneous rock. It contains large crystals (phenocrysts) within a fine-grained matrix. The phenocrysts are usually made up of minerals such as quartz, feldspar, and mica.
What is the cooling rate of a porphyritic rock?
The cooling rate of a porphyritic rock can vary depending on the specific conditions during its formation, but generally it is considered to be intermediate. This means that porphyritic rocks cool at a moderate rate, which allows for the formation of both large crystals (phenocrysts) and finer-grained matrix.

Is Granite an organic sedimentary rock?
granite is an intrusive igneous rock
What is the texture of granit?
Granite has a phaneritic texture. This means that it has crystals 1-10 mm. It was formed from slow cooling, viscous magma, and/or good nucleation. Crystalline. Coarse-grained. Crystals visible without magnification.

What type rock is wave rock?
Wave Rock, near Hyden in Western Australia, is made of granite. Specifically, it is an inselberg made up of medium and coarse-grained porphyritic granite. Its streaked colouring comes from water running down the surface, dissolving minerals and washing chemical deposits such as iron oxide and carbonates as it goes.
What is an igneous rock with both large and small crystals?
The type of igneous rock that has large crystals surrounded by smaller crystals is not a rock but a porphyritic texture. This texture describes igneous rock that has porphyrites, or large crystals, with surrounding tiny particles, or groundmass.
What are porphyritic rocks?
Porphyritic Rocks are rocks that have big and small crystal's like the Igneous Rock "Andesite".
Which of the following is not a feature of sedimentary rock?
