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.
Graphite can be found in all types of rock (igneous, metamorphic, and sedimentary). Although, it originates from igneous rocks, and is generally most economic in metamorphic rocks.
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.
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.
Amethyst is a variety of quartz, which is a mineral that is formed in igneous and metamorphic rocks. Amethyst is typically formed in hydrothermal veins within igneous rocks or as a product of metamorphism in rocks rich in silica. Therefore, amethyst is not classified as a specific rock type, but rather a mineral that can be found in both igneous and metamorphic rocks.
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.
Graphite can be found in all types of rock (igneous, metamorphic, and sedimentary). Although, it originates from igneous rocks, and is generally most economic in metamorphic rocks.
Igneous rocks can be found in the mountains, which are partially composed of Precambrian plutonic rock.

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.
Igneous rocks are found at the base of a volcano.
Extrusive igneous rocks are usually fine grained.
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.
igneous rocks,sedimentary rocks, and metamorphic rocks.
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.
