If you've ever been to your local lawn and garden store or drove past one along a well driven highway, and you've taken a good long look at some of the beautiful water features that are there on display and said to yourself that you would love to someday have one of those designs in your own backyard, then you have to begin with design and just what type of rock you will use for that great water feature that you dream about.
There are many water kinds of water gardens and Koi ponds that can either have granite water features or slate water features, and since these are the types of stones that most water design companies use as part of their water feature designs it would be a great idea to focus on these two different types of rock, as they make fabulous rock formations for your pond's granite water features and also for beautiful slate water features.
Granite rocks can usually be found in the Earth's crust in its continental plates and have several distinguishing features to them and the first thing the fact that they are termed Metamorphic rock. This term means that the granite is formed in places by extreme metasomatism, when fluids such as potassium are brought in the core rock and other minerals such as calcium are naturally extracted from the rock, to help form the final composition of the granite stones. Another thing to talk about is the actual colour of theses rocks. Their colours usually range from a dark grey colour to a light pink hue.
The size of granite rock is almost always large in size, and when used as part of a water garden or Koi pond they can be used as they are or they may need to be broken down to a certain workable size and shaped to fit certain architectural design needs of the rock garden or Koi pond.
Slate rock is also a metamorphic type of stone that is derived from shale. Shale is a type of stone, composed of volcanic ash and clay that is formed through the natural process of low grade regional metamorphism. The colour of this rock ranges in colour depending on the country and area where it is found, for example in North wales the slate found there can range in colour from the usual grey to hues of cyan, green or purple. Slate's composition is made up of several different minerals which can include quartz, chlorite, pyrite, and graphite.
As far as using these stones for design in your water garden or Koi pond, the same issues persist, as you may have to cut and shape these stones to fit your individual design needs for your water features design. We hope that you have found this article informative, and that it may help you in your decision to choose which type of stone will be preferable to your needs in your own water garden or pond.
