Is andesite a foliated rock?
No. Foliation is a term that applies to metamorphic rocks. Andesite is igneous.
Does Andesite contain CaCO3?
No. Calcium carbonate is found in sedimentary and metamorphic rocks. Igneous rocks such as andesite are composed almost entirely of silicates.
What is the most common rocks in the Philippines?
andesite
How old is andesite?
Andesite is not any age in particular. Some deposites of andesite may be hundreds of millions of years old. However, since andesite is volcanic, some andesite rocks may only be minutes old.
What are porphyritic rocks?
Porphyritic Rocks are rocks that have big and small crystal's like the Igneous Rock "Andesite".
What are types of volcanic rock?
Volcanic rocks are extrusive igneous rocks.
Is andesite foliated or nonfoliated?
Andesite is a nonfoliated rock, meaning it does not have a layered or banded appearance like foliated rocks such as slate or schist. Andesite forms from volcanic activity and solidifies without undergoing the intense pressure and heat required for foliation to occur.
What igneous rocks cool above ground?
Igneous rocks that cool above ground are called extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks form when magma erupts onto the Earth's surface and cools rapidly.
Is andesite nonfoliated?
Andesite is typically classified as an igneous rock, specifically a volcanic rock, and is not categorized as either foliated or nonfoliated since those terms primarily apply to metamorphic rocks. Foliation refers to the alignment of mineral grains under pressure, which is not relevant to andesite. Instead, andesite has a fine-grained texture and can contain a mix of minerals, but it lacks the layered or banded appearance characteristic of foliated rocks.
Is andesite basic or acid?
Andesite has an intermediate composition between "basic" and "acid."
What types of igneos rocks are found in Mount Tambora?
Mount Tambora in Indonesia primarily consists of andesite and dacite rocks. These igneous rocks were formed from the cooling and solidification of magma beneath the Earth's surface. Andesite is a fine-grained rock that is intermediate in composition between basalt and rhyolite, while dacite is a fine-grained volcanic rock with a similar composition to andesite but with higher silica content.
What are some words about rocks that begin with the letter A?
abrasion agate amygdule andesite arkose
