What are River Rocks | Some Benefits of These Rocks

Almost everywhere around us in Australia, we find different types of rocks. When found near rivers, lakes, ponds, they have termed river rocks. The ones found near beaches and oceans are the beach rocks. In nearly every natural setting, you may find a variety of intriguing and unique rock specimens. The worth of these rocks is determined by their kind, quantity, and shape.

What are River Rocks?

River rock refers to the wide variety of rocks formed by eroded topsoil. It has a smooth and rounded texture due to flowing water. If you have ever visited a river bank you might have noticed those various roundish stones of different sizes and colours. The ones that are totally submerged in the river are slippery when you step on them while the one on the banks are dry and clean. River stones come in a variety of shapes and sizes, depending on the source stone from which they split, and the degree of damage water was able to cause.

The Journey of the River Rocks:

  1. River rocks begin as sharp stones and gravels when they break away from hillsides or slopes as they form naturally.
  2. Smaller stones are formed when the parent rocks break off. The parent rocks are bigger and much more geometric in appearance.
  3. The rocks start to wear and acquire a more curved form when water erosion occurs.
  4. Rocks will move, collide, and split into smaller parts if the flow is powerful.
  5. Valleys with running rivers or coastal lines with hills overlooking sea waves are typical habitats.
  6. Smaller rocks may move with the current, rounding and smoothing out as they go until they wind up along the banks of waterways, in riverbeds, or on beach coastlines.
  7. The longer and more forcefully water erode the rocks, the more spherical they get.

River rocks that occur naturally include granite, schist, and basalt (or volcanic) river stones. River stones that have been artificially refined are generally taken from rock quarries. Smaller pebbles are gathered from shattered boulders and sold in these places for the public to use.

Characteristics of River Rocks:

According to the topography of the riverbed where the rocks were discovered, river stones might be metamorphic, sedimentary, or igneous. These rocks are available in a variety of shapes, sizes, hues, and roughness. The main features depend on the origin, the path and the region of the river flow.

However, Some of Its Characteristics Are:

  • Because silt of pebbles from various origins is combined, the hues of river rocks are blended.

For Example

  1. Brown, pink, or red-tinted rock can be visible if iron-oxide is prevalent.
  2. They will be yellow, brown, or orange if they include an aqueous iron oxide.
  3. Other shades include blue or purple, which indicates manganese oxide. The black colour indicates iron sulphate.
  • River Rocks have a texture that is determined by the parent rocks. It might be smooth and non-porous or somewhat permeable and semi-polished.
  • Depending on the mineral content of the parent material, the density of these rocks ranges between 2.65 and 3.00g/cm3.
  • The hardness will be between 6 and 6.5, making these rocks robust. 

Advantages and Uses of River Rocks

  • The little quantities of minerals that drain from these stones will feed aquatic plants with critical metals and other minerals.
  • In the saline tanks, limestone-based stones will give calcium to aquatic animals and coral.
  • They are used in terrariums and aquariums as floor toppers.
  • They’re utilized for both decorative and functional purposes.
  • They are used to line a yard, construct a pathway, create boundaries around constructions and terraces, and decorate fountains and ponds, among other things.
  • Moreover, river rocks are used in a variety of Australian industries. Since these rocks are formed easily by water, they can be found all over the world. It is inexpensive to obtain, and if you’re lucky, you can find it for free. Aesthetics, healthcare, architecture, and, most famously, the terrarium hobby are all examples of this.
