In this Earthcache you will learn alot about Granite and the local mountaineer Banjo Bannon. The cordinates will take you to a monolith raised in his honour for climbing Everest.
Granite
What is Granite? Granite is a light-colored igneous rock with grains large enough to be visible with the unaided eye. It forms from the slow crystallization of magma below Earth's surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles, and other minerals. This mineral composition usually gives granite a red, pink, gray, or white color with dark mineral grains visible throughout the rock.
The Best-Known Igneous Rock Granite . 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 encounter in daily life. These include counter tops, floor tiles, paving stone, curbing, stair treads, building veneer, and cemetery monuments. Granite is used all around us - especially if you live in a city.
So what is an Igneous rock and how is it formed ?.
Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses.
So now you know a little about granite and how its formed, to find out a wee bit more about Banjo Bannon you will have to visit this location.
To log this find you will have to answer these questions, They are meant to prove that you are learning and that you actually visited this cool spot. i would love for you to upload a picture of yourselves at gz, this is not a logging requirement, it would just be cool...
