The excellent geodes found along the Uruguay-Brazil border are from a region with significant deposits. German geochemists studied this region. The team of H. Albert Gilg of Technical University Munchen studied the deposits using techniques commonly utilized in geochemist research.

The deposits extracted from various lava flows originated from the Parana Continental Flood basalt province. It is regarded as one of the largest outbursts of molten rock known to have happened in the world. It’s estimated that approximately 800,000 cubic kilometers of lava have been extruded from this region over the last 11 million years.

The eruption occurred during the South Atlantic Ocean’s opening phase during the Cretaceous period, which happened around 130 million years ago. Although most of the lava flows are known to have amethyst cathedral geodes, only a few are known to have these deposits.

Stage 1 

The researchers proposed a two-stage model to explain the various phases of the crystal formation process. In the first stage, the large hollows formed due to the release of volcanic gases from the lava. As the gas bubbles formed, they rose. Similar to the bubbles that form when soda pop is poured, the crystal structures eventually rise as they are formed.

As the temperature of the lava increased, the thick and sticky material trapped the gas bubbles and formed tubular and bulbous shapes. These structures could be seen in the mines when the geodes are in place. However, these hollow cavities are not filled with crystal structures.

Stage 2 

The second stage involved forming various crystal structures, such as amethyst, gypsum, and quartz. One of the most important factors that contributed to the development of these materials was the presence of liquid and gas bubbles within the minerals.

Using sophisticated instruments, researchers analyzed the various characteristics of the fluid inclusions, such as their composition. They were able to determine that the deposits were filled with salty water. The water’s temperature could be as low as 50 degrees Celsius during the mineral formation process.

What Was The Source Of The Fluids? 

Through the data collected by the researchers, it was revealed that the geodes’ fluids came from the deposits that formed around 130 million years ago. However, the green celadonite, which makes up the geodes’ rinds, formed around 70 million years ago.

The data collected from the fluid inclusions also gave researchers new insight into the crystal formation process. They discovered that the overlying lava flows were filled with water from an underground aquifer, similar to the fluids found in the geodes’ deposits. If the area had been tilted and lifted 70 million years ago, the water would have forced its way into the overlying lava.

During the lava flow, the water was likely transported to the region by the volcanic glass, which breaks down over time and allows the chemicals to be readily soluble in the water. These chemicals then flowed into the cavities and formed crystal structures.

The combination of geologic conditions and the natural processes that have occurred over millions of years can be very rare. Understanding the process involved in crystal formation provides geologists with the necessary tools to find new deposits.

Uses of the Amethyst Cathedral 

According to ancient Greece, it could help ward off alcohol consumption. In ancient Egypt, the stone was used to represent a goat, symbolizing the enemy of vineyards and vines. Due to its vibrant purple color, it has also been regarded as a symbol of royalty. Today, amethyst is used in various practices and beliefs across the world.

Zodiac Associations 

February is the birthstone of amethyst, and it can provide various benefits to people born under the signs of Aquarius and Pisces. For those under the sign of Aquarius, it can help them develop a sense of spiritual guidance. They are often eager to try something new and are willing to sacrifice their old ways to forge a new one. With the stone, they can also work toward their goals more accurately and patiently.

While being under the sign of Aquarius is known to be very demanding, those under the sign of Pisces are more likely to put their emotional well-being first. With the help of the stone, they can also develop a deeper understanding of themselves. It can help them identify their root causes and find a way to relieve their stress.

People born under other zodiac signs, such as February’s sign of Aries, can also benefit from the stone. It can help them healthily channel their ambitions.

Chakras 

In addition to being helpful in meditation, crystals and geodes can also be used to enhance the connection between the crown and the other energy centers. The crown chakra is the seventh energy center, regarded as the culmination of the other energy centers.

The crown chakra is a vital part of our being and can help us connect with the divine and our physical body. Using an amethyst can strengthen this connection and help us find inspiration and enlightenment during meditation.

Feng Shui 

People who practice Feng Shui commonly use crystals and gemstones to achieve a balanced energy flow in their homes. Due to its versatile properties, it can be used in various ways. For instance, people can use it in multiple sectors of the Feng Bagua map. This method divides a room or home into nine sections, each with its own purpose and energy.

In the relationship and love sector of the Bagua map, amethyst can help people feel valued and supported. It can also be used outside of the Bagua map. For instance, placing an amethyst near the front door can help create a more balanced energy flow in the home.

Does The Size of The Amethyst Cathedral Matter? 

One of the most important factors people consider when choosing a large amethyst cathedral is its healing properties. However, the cost of this item can be very prohibitive for most people. A wide variety of sizes and shapes of amethyst cathedral geodes are available. Their value can be determined by various factors, such as their overall size, depth of color, and crystal points.

Although large amethyst cathedrals can provide a wide range of healing properties, smaller amethyst cathedrals can provide the same results. For instance, while a large amethyst cathedral can provide energy to a whole house, a small one can only do so in a certain area.
