A desert-wide area could be bombarded by meteorites, wiping out all life on Earth. Subsequent meteor hits would shatter the pre-existing glass and turn it into sand. Yet, in spite of these threats, crystals continue to grow and be discovered. The most stunning formation of these natural wonders is in Naica cave, where the crystals are believed to have grown for millions of years under perfect conditions. Another spectacular sight is the Cave of Swords, where crystals are more abundant but smaller in size. Of course, there are places where there are no crystals at all.
Selenite is a powerful healing crystal
Selenite is a powerful healing crystal that can help you overcome negative emotions. When placed in your palms, Selenite can stabilize your erratic emotions. It can also help you manage your intense emotions. Selenite can help you to feel more at peace with yourself and restore the connection you have with others. It can also help you to see your true light, allowing you to appreciate nature’s beauty and its healing properties.
This crystal is an excellent choice for meditation, since it promotes deep relaxation and clears blockages. When placed on your windowsill, Selenite helps you to sleep well at night. It can also clear your energy field and help you have a better night’s sleep. Besides being a powerful healing crystal, Selenite can also help you promote good conversations over the dinner table. It helps you to stop overthinking and get more clarity.
Desert roses are flattened on the c axis
The rosette-like crystal clusters that form in arid conditions are called desert roses. They contain gypsum, barite, sand grains, and poikilotopic sand inclusions. Their flat c axis indicates that they are poikilotopic and enclose smaller crystals. Moreover, they display characteristic gypsum cleavage planes, and they form an overall rose-like crystal structure.
The desert rose structure was studied using a medical CT scanner. Different disks and connections were placed around the rose. The disks were traced through all cross-sections in order to obtain a complete map of the entire structure. This process was repeated several times, until the morphology of the whole desert rose became clear. The resulting image of the desert rose structure was shown in Figure 3.
Geodes are unique in composition
Geodes are formed by sedimentation of minerals that have dissolved in the surrounding rock. Geodes typically consist of quartz and calcite, but some geodes contain other minerals as well. Quartz geodes are formed in volcanic rock, while agate and jasper are formed in sedimentary rocks. Geodes have distinct color and composition due to the various dissolved minerals found in them. Their compositions are largely unique to their specific location.
Most geodes are made of quartz, the common mineral found in nature. Amethyst geodes are purple varieties of quartz. They form in volcanic or sedimentary environments. Quartz geodes are typically formed in a cavity inside a rock, which is connected to volcanic activity. Geodes, like their name suggests, look solid on the surface, but they are actually porous. Their pores are small, which helps explain their unique appearance.
They form in arid conditions
Desert rose: This delicate rose-like formation is composed of clusters of gypsum and baryte crystals surrounded by abundant sand grains. These crystals form in arid conditions and require a relatively large source of CaSO4 and irregular seasonal fluctuations to survive. Desert roses are found all over the world and are often called sand roses, desert patina, rock rust, or selenite rose.
Wind variation: The direction, velocity, and turbulence of wind flow are important in shaping deserts. Because most great deserts are found in subtropical regions of high atmospheric pressure, winds flow clockwise in the Northern Hemisphere and counter-clockwise in the Southern Hemisphere. Winds originating from high-pressure systems dip in the east and are reflected by dunes in North America and the Central Asia. Westerly winds, on the other hand, originate from depressions moving eastwards and mold the dunes in the northern Sahara.
They are rare
The Milky White Crystals of Naica, Mexico, tower above a horseshoe-shaped cave. They are 290 meters high and more than a meter wide. Researchers say the crystals are millions of years old and grew indefinitely due to the water’s temperature staying in a transition zone between gypsum and anhydrite. Scientists believe they are a result of just the right conditions: the exact balance between a slow cooling rate and a high enough temperature for crystal growth.
Ancient peoples admired crystals for their beauty, cultural significance, and religious significance. The ancient people may have valued them for similar purposes, as the site of their discovery has a spiritual meaning to modern people. While it is not known for sure, some researchers believe that ancient people used Ga-Mohana Hill for the same purposes, their environment was significantly wetter than today. This was especially true in ancient times, when it was much harder for humans to survive than today’s coastal communities.
