This week’s theme for the Flickr Macro Mondays group is “Geology.” From this week’s instructions (from George Frizzell):
Geology is the study of rocks and geologists are the people who study them! I would think that most of us did a bit of study on this subject in our early years in geography classes and understand that the Earths crust is made of rock, and rock is made of natural substances called MINERALS. There are three main types of rock—sedimentary, igneous, and metamorphic rock. Each type is produced in different ways. The oldest rocks on Earth were formed about 3.8 billion years ago.
In many countries both the words “rocks” and “stones” are interchangeable in their usage meaning the same thing, and both are considered appropriate for this theme. This week we will be looking closely at rock. So, let’s see what rock can be discovered around you where you live, and start photographing rock, get real close into the detail and get right into the shadows and cracks and you will be amazed at the colours and textures that are revealed.
Examples of rock are:
Igneous Rocks. Basalt. Granite, Pumice.
Metamorphic Rocks. Quartzite. Marble. Slate.
Sedimentary Rocks. Sandstone. Shale, Pebbles, Chalk.
IMPORTANT – before posting your photo:
Bricks and concrete are not considered rock and and will be excluded from the pool if submitted.
If you know what kind of rock that you are photographing, please feel free to put this information into the title or the description of your macro photograph. Its not mandatory but I’m sure it will be interesting information for our members.
True Beauty Lies Within
Dominic found an ordinary looking rock earlier this summer during a friend’s birthday party at Natural Bridge Caverns. The kids were exploring the mining activity and were encouraged to throw the rocks on the ground to see if they would break open to reveal a treasure. Voilà… he found this geode and it’s a perfect subject for this week’s Macro Monday theme of geology. This is a good reminder to not make assumptions about the value of something based on its exterior appearance. True beauty really does lie within.
