This is an EarthCache and has special requirements for logging it. You cannot log a Found It without responding to the logging requirements set out below.
Only one find claim per Message. Each Geocacher claiming a find must submit an individual response. One team can not lodge a response on behalf of a group of people.
Sometimes it's possible to get up close and personal with a rock face.
The cache is near the Barrington Tops, which is part of the Mount Royal Range, a spur of the Great Dividing Range. Barrington Tops is a plateau between two of the large peaks in the range, and the park is believed to be an extinct volcano.
The mountain ranges are made up of a mixture of sedimentary rocks with a granite top. Erosion has weathered the granite and rounded granite boulders can be seen. Estimates put the age of the rock at 300 to 400 million years, well before Australia separated from Gondwana.
Granite: a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Huh?
OK. Let's start at the beginning: Intrusive rocks are a type of igneous rock which are formed from cooled magma - the stuff that come up in a volcano. Intrusive rocks are igneous rocks that form from crystallized magma beneath the earth's surface. Compare this to the other main category of igneous rocks: extrusive rocks, which are igneous rocks formed on the surface.
The Felsic part means that they are relatively rich in elements that form feldspar and quartz. These are usually the pinkish (feldspar) or whitish (quartz) streaks in the granite.
The crystals you can see in granite are referred to as phaneritic.
So there you have it: felsic intrusive igneous rock that is granular and phaneritic in texture.
Now here is your task:
* Describe which of the elements described above are evident at GZ, and on which rock face did you make your observations.
* Take of photo of yourself OR your GPS to show a view of GZ. Include it in your message, but please do not post it in your log, it might give too much away.
When you have your responses to the questions above, please MESSAGE them to me if possible. I don't respond to emails very well. I will contact you once I have read your MESSAGE. But you can log your find in the meantime, and just say that you have MESSAGED your answers to the CO.
Happy Earthcaching!
