Yes.
There are a is number of extinct volcanoes in Australia which are of course igneous, including a chain stretching from Cairns through the Glasshouse Mountains in south-eastern Queensland to Mount Napier in Western Victoria. (Formed by the Eastern Australian Hotspot.) Besides basaltic cores such as the Glasshouse Mountains, Mount Warning, etc. these produced large areas of flow basalts and rhyolites over the Atherton Tableland through the New England Tableland and so on southwards.
Besides the volcanic rocks, there are intrusive adamellites at Bundaberg, Smoky Cape, and Moruya Head. Large areas of Western Australia have granitic bedrocks.
The coal, iron ore, and alumina mined in Australia are all of sedimentary origin, but the silver, lead, copper, and gold mines in Mount Isa, Broken Hill, Kalgoorlie etc. are all extracted from igneous formations.

Yes, igneous rocks can be found in Australia. Some examples include granite, basalt, and dolerite, which are formed from the cooling and solidification of molten rock below or at the Earth's surface. These rocks can be found in various regions of Australia, such as in parts of Western Australia, New South Wales, and Tasmania.

What type of rocks is graphite found in?
Graphite is primarily found in metamorphic rocks such as schist and gneiss. It can also be found in some igneous rocks like granite and pegmatite.
Is peridot in igneous rock?
Yes, peridot is often found in igneous rocks, particularly in basaltic lavas and ultramafic rocks like peridotite. It can also be found in some metamorphic rocks that formed from the alteration of these igneous rocks.
What types of rocks are found in Australia?
Australia has a variety of rocks including sandstone, limestone, granite, and basalt. These rocks are found throughout the country in different regions, each with its unique geological history and formation processes. Additionally, Australia is known for its opal deposits, with the country being one of the largest producers of this precious stone.
Does an igneous rock contain iron?
Igneous rocks can contain iron, but not all igneous rocks do. The presence of iron in an igneous rock depends on the composition of the magma from which the rock formed. Iron can be found in minerals such as magnetite, hematite, and pyroxene within certain igneous rocks.
Is amethyst igneous metamorphic or sedimentary?
Amethyst is a type of quartz mineral commonly found in igneous rocks, which form from the cooling and solidification of magma. While quartz itself can also be found in sedimentary and metamorphic rocks, amethyst specifically is most commonly associated with igneous rocks.
What type of rocks is graphite found in?
Graphite is primarily found in metamorphic rocks such as schist and gneiss. It can also be found in some igneous rocks like granite and pegmatite.
Where can igneous rocks be found in Colorado?
Igneous rocks can be found in the mountains, which are partially composed of Precambrian plutonic rock.

Where is zircon found?
Zircon is found in a variety of locations worldwide, including Australia, Brazil, Sri Lanka, and the United States. It is often found in igneous and metamorphic rocks, as well as in alluvial deposits.
Where are inclusions found?
In igneous rocks.
What grain type is found in extrusive igneous rocks?
Extrusive igneous rocks are usually fine grained.
Can you use igneous in a sentence?
Igneous rocks are found at the base of a volcano.
What are two types of igneous rocks?
Two types of igneous rocks are intrusive igneous rocks, which form from magma that cools and solidifies beneath the Earth's surface, and extrusive igneous rocks, which form from lava that cools and solidifies on the Earth's surface.
What types of rocks are found in volcanoes?
igneous rocks,sedimentary rocks, and metamorphic rocks.
Where can igneous rocks be commonly found?
Igneous rocks can commonly be found near volcanoes. They are made when lava is cooled and becomes a solid. The oceanic plates are mostly made of igneous rock.
What types of rocks are found in Australia?
