Gabbro is a type of igneous rock which is used for paving stones and is also known by the name of ‘black granite’, which is a type of headstone. I also know of big granite boulders on my Nan’s farm in Lancefield and they were formed by a volcano millions of years ago. They are AWESOME fun to climb on!
Diorite is an intrusive rock intermediate in composition between gabbro and granite. It is produced in volcanic arcs, and in mountain building where it can occur in large volumes as batholiths in the roots of mountains. Diorite is used for making the outsides of a house.
Dolerite is an igneous, volcanic rock. It has a fine, but visible texture. When it is fresh it is black, dark – grey, green and may be mottled black and white. Dolerite is used as crushed stone and ornamental stone. It is a common rock in Tasmania and has been used in buildings and for landscaping.
Granite is a type of igneous rock and is the best-known igneous rock. Many people recognize granite because it is the most common igneous rock found at Earth’s surface and because granite is used to make many objects that we use in daily life. These include counter tops, floor tiles, paving stone and curbing. Granite is used all around us – mostly if you live in a city.
Rhyolite is a type of igneous rock that was used for making stone tools and weapons such as axe heads, spear points and arrowheads. Now it is sometimes used for building materials and manufacturing.
I found an igneous rock called Obsidian. It is a dark-colored volcanic glass that forms from the very rapid cooling of molten rock material.It cools so rapidly that crystals do not form.I found this on a website called geology.com.au.The rock was really shiny and black.It can be very funny shapes and the one I saw looked like a couch.

Granite is used for counter tops, floor tiles, curbing, paving stone, stair treads, building veneer & cemetery monuments.
It is also very common in the city, so next time you go to the city keep an eye out!
Granite is used in tables, pyramids and floors.
Well done, NT! Granite is used in lots of places I didn’t know!
Obsidian is a extrusive igneous rock . It is used for jewellery, cutting tools and mirrors. It has a hardness of 5.5.
Good work ZH, Obsidian sounds really hard. What does 5.5 stand for? Excellent use of our topic language.

Excellent work, JM. Granite is very useful it seems. Excellent research and well written.
Pumice is an igneous rock that is used for making concrete and scrubbing dead skin off your feet. Pumice is so light it can even float.

Well done, CM. Sounds like Rhyolite must be very strong. Excellent research!
