Rocks With Holes At The Beach: A Guide To The 5 Most Common You’ll Spot

Are you looking for rocks with holes that you can spot on the beach?

The good news is there are plenty of them, but you need to know which one to pick. 

Don’t fret.

This article sheds light on some information about rare stones that you can find on the beach.

This article won’t just be valuable in helping you identify rocks with holes, but also know their commercial value as well.  

Rocks With Holes At The Beach (Let’s Get Started)

In geology, we refer to beach rocks as stones with no context.

What do we mean about that? 

First, we mean it’s nearly impossible to tell how each beach rock has formed or where it has originated from.

Secondly, we mean each rock you will find will have a different texture, color, and so on. 

That said, rocks with holes found at the beach are some fascinating types.

People still think stones with holes running through them are an omen of luck.

In contrast, a rock with holes could be a perfect decor ornament.

It all depends on what you want to use with a stone.

What is the formation process of rocks with holes?

There are two formation processes involved in the formation of each rock with a hole that you will spot.

The first natural process is erosion, which usually affects a delicate part of any rock.

Waves at the seas turbulently cause another transformation process as well.  

Another cause of holes in rocks includes burrowing worms or mollusks, such as piddocks.

Types of rocks

.All rocks, including those you can find on the beach, fall under one of the three categories:

  •  Igneous, sedimentary, and metamorphic. 

Let’s explain each category to you.

  • Igneous rocks mostly form under scorching temperatures, generally under the Earth’s surface. Some examples include basalt, obsidian, and pumice.
  • Sedimentary rocks are any rocks on the beach that have hardened into compact sediment. Examples of sedimentary rocks include fossil stones, sandstone, shale, conglomerates, and breccia.
  • Metamorphic rocks start as other types of rock but substantially change from their original igneous shape to something else. Typically, metamorphic rocks are slate, marble, quartzite, and gneiss.

Here are types of beach stones with holes that you should know:

Michigan’s Igneous Rock

You can find this igneous volcanic rock in Lake Michigan Beach.

You can easily recognize it by its well-developed crystals that were formed through slow cooling temperatures.

Also, most igneous rocks are dark, which means they are noticeable.

It is one of those rare gems that formed billions of years ago.

It shapes from the cooling of the lava and becomes large crystals. 

Some igneous rocks have a hole or two.

And the history behind this rock is quite fascinating.

The name comes from the Latin word “Ignis,” which means fire.

You can use this durable rock as decor or even build walls. 

Where to find it? 

When you go to Michigan, you’re likely to find the Igneous Rock in places such as Horseshoe Harbor in Copper Beach and Black Rocks Volcanic Formations in Presque Isle. 

Pebbles with holes 

Another fascinating rock you should take a look at is pebble with holes.

You can use them in your jewelry collection, interior decor, and more.

They come in various colors, and they are usually pale gray, with multiple holes on the side.

Where to find them? 

 You can pick pebbles with holes on the beaches along the Jurassic Coast in Dorset and other U.K. locations.

Basalt with holes

Basalt is another igneous rock that you can find at the beach.

Basalts are usually vesicular, but you are likely to find a few that have holes. 

Spotting it is pretty easy; Basalt will attract you with its dark or reddish-brown colors.

You will find this precious rock on the surface of the ocean, but it is also common to find it veined with exquisite quartz.

You can use Basalt rock for a variety of things.

For starters, you can crush it and use it as an aggregate for construction projects.

Other people use Basalt rock as a filter stone in drain fields or for decor purposes. 

Where to find it?

You can pick Basalt all under any ocean and in other areas where Earth’s crust is thin.

For instance, in the Isle Royale-Keweenaw region, 90% of Earth’s surface is basalt lava.

On the coast of Hawaii, there is Basalt that flows into the Pacific Ocean.

There are other multiple locations where hot lava streams into the ocean, too.  

Rhyolite with tiny holes

You are likely to find rhyolite rocks that have tiny holes.

They come in many colors, from red, brown, pink, white, or gray.

They have a unique banding that forms as Rhyolite cools or hardens.

Interestingly, Rhyolite has a bit of quartz, plagioclase, and sanidine, with tiny hornblende and biotite.

While Rhyolite rarely comes from oceanic eruptions, you will likely pick any of them at the beach.

Rhyolite is mainly used for construction, building roads, decorating, abrasive, and jewelry.

Where to find it?

You can find Rhyolite rocks in many countries.

For instance, you can find it in countries like India, New Zealand, Germany, Iceland, India, and China.

Diabase rock

You can also find Diabase rock with holes at the beach.

You won’t miss this gem with its dark-colored look, making it stand out from other stones.

Plus, Diabase has a slightly coarser texture, making it ideal for decorations, construction, and a railroad bed. 

You can use Diabase as a building stone, too.

In Tasmania, people use it to erect dry-stone farm walls and for landscaping as well. 

Where to find it? 

Diabase is typically available in shallow intrusive bodies such as dikes and sills. You can find it in Namibia, Northern Ireland, Arizona, and other places. In the Death Valley region of California, Precambrian diabase intrusions are now a vital talc deposit.

Last Thoughts 

Remember, most beach stones you will find are produced by a variety of things.

From wind to eruptions, waves, and just about anything.

Additionally, they will differ in texture, color, or size.

So, before you pick a stone, have a good idea of what kind you need, and for what type of project.
