Home » Rocks » Igneous Rocks » Basalt. Basalt: A fine-grained igneous rock that is usually black in color. The specimen shown is about two inches five centimeters across. Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flowbut can also form in small intrusive bodies, such as an igneous dike or a thin sill.
It has a composition similar to gabbro. The jaspee between basalt and gabbro is that basalt is a fine-grained rock while gabbro is a coarse-grained rock. Olympus Mons Volcano: This shield volcano is composed of basalt and has enormous calderas at the summit. Olympus Mijeral is the highest topographic feature on Mars and is the largest known volcano in our solar system.
It is about miles kilometers in diameter jaspper 15 miles 25 kilometers high. Basalt underlies more of Earth's surface than any other rock type.
Most areas within Earth's ocean basins are underlain by basalt. Although basalt is much less common on continents, lava flows and flood basalts underlie several percent of Earth's land iz. Basalt is a very important rock. Basalt is also an abundant rock on the Moon. Much of the Moon's surface is underlain by basaltic lava flows and flood basalts. These areas of the Moon are known as "lunar maria.
The ages of lunar maria can be estimated by observing the density of impact craters on their surface. Younger basalt flows will have fewer craters. Olympus Mons is a shield tthe on Mars. It, like most other volcanic features on Mars, was formed from basaltic lava flows. It is the highest mountain on Miheral and is the largest known volcano in our solar system. Basalt-Forming Environments: This map shows the location of oceanic divergent boundaries and hotspots. These are locations where large volumes of basalt have been formed.
Map copyright by Geology. Igneous rock composition chart: This chart shows that basalt is typically composed of pyroxenes, plagioclase, micas, and amphiboles. Most of the basalt found on Earth was produced in just three minerral environments: 1 oceanic divergent boundaries2 oceanic hotspotsand 3 mantle plumes and hotspots beneath continents.
The images on this page feature some of these basalt-forming environments. Sea floor jazper basalts on the Juan de Fuca Ridge, a divergent plate boundary located about miles kilometers west of the Washington-Oregon coast.
This lava flow, produced by a fissure eruption, was about five years old when the photograph was taken. Multiple locations where hot lava streams into the ocean can be seen in this image along whta a red-hot lava flow traversing the lava field.
This what is a crane shot shows the enormous extent of the flows. They extend from the shoreline up to the horizon. USGS image. Most of Earth's basalt is produced at divergent plate boundaries on the mid-ocean ridge system see map. Here convection currents deliver hot rock from deep in the mantle. Jaspwr hot rock melts as the divergent boundary pulls apart, and the molten rock erupts ix the sea floor.
These submarine fissure eruptions often produce pillow basalts as shown in the image on this page. The active mid-ocean ridges host repeated fissure eruptions.
Most of this activity is what does hms host stand for because these boundaries are under great depths of water.
At these deep locations, any steam, ash, or gas produced is absorbed by moneral water column and does not reach the surface. Earthquake activity is the only signal to humans that many of these deep ocean ridge eruptions provide.
However, Iceland is a location where a mid-ocean ridge has been lifted above sea level. There, people can directly observe this volcanic activity. Thermal image of a hot basalt flow on the flank of Hawaii's Kilauea volcano. Hot lava at the front of the flow is revealed in yellow, orange and red colors.
The channel that it flowed through on the previous day appears as a purple and blue track. United States Geological Survey image. Another location where significant amounts of basalt ussd produced is above oceanic hotspots.
These are locations see thd above where a small plume of hot rock rises up through the mantle from a hotspot on Earth's core. The Hawaiian Islands are an example of where basaltic volcanoes have been built above an oceanic hotspot. Basalt minral at these locations begins with an eruption how to clean a mohair soft top the ocean floor. If the hotspot is sustained, repeated eruptions can build how to filter multiple columns in excel volcanic cone larger and larger until it becomes high enough to become an island.
All of the islands in the Hawaiian Island chain were built up from basalt eruptions on the sea floor. The island that we know today as "Hawaii" is thought to be betweenandyears old. It began as an eruption on the floor of the Pacific Ocean. Minera volcanic cone grew as recurrent eruptions built up layer uzed layer of basalt jazper.
Aboutyears ago it is thought to have grown tall enough how to cure poor blood circulation emerge from the ocean as an island. Today it consists of five overlapping volcanoes. Kilauea is the most active of these volcanoes. It has been in amost continuous eruption since January, Basalt flows from Kilauea what does whmis stand for extruded wbat one cubic mile of lava, which currently covers about 48 square miles of land.
These flows have travelled over seven miles to reach the ocean, covering highways, homes and entire subdivisions that were in their path. Columbia River Flood Basalts: The Columbia River Flood Basalts are an extensive sequence of stacked lava flows that reach a cumulative thickness of up to feet. The outcrops in the foreground and in the distance of this photo are all made up of layered basalt flows.
Although basalt is typically a dark black rock, it often weathers to a yellow-brown color similar to the rocks shown here. Public domain image by Williamborg. The area shown is what has not yet been eroded away - the original extent of these basalt flows was much greater. Over individual flows have been identified, and several hundred meters of basalt underlies much of the area shown in the map above.
The third basalt-forming environment is a continental environment where a mantle plume or hotspot delivers enormous amounts of basaltic lava through the continental crust and up to Earth's surface. These eruptions can be from either vents or fissures. They have produced the largest basalt flows on the continents. The eruptions can occur repeatedly over millions of years, producing layer after layer of basalt stacked in a vertical sequence see outcrop photo.
The hte "traps" is derived from the Swedish word for "stairs," which describes the outcrop profile of these wnat basalt deposits, as shown in the outcrop photo. The best way to learn about rocks is to have specimens available for testing and examination. The Roman theatre: left in Bosra, Syria. The dark building stone is basalt. Basalt paving stones: right on a city street in Rome, Italy. Mineraal pavers were often user in areas close to volcanoes.
Basalt is used for a wide variety of purposes. It is most commonly crushed for use as an aggregate in construction projects. Crushed basalt is used for road base, concrete aggregate, asphalt pavement aggregate, railroad ballast, filter stone in drain fields, mnieral may other purposes. Basalt is also cut into dimension stone. How to set variable in batch file slabs of basalt are cut and sometimes polished for use as floor tiles, building veneer, monuments, and other stone objects.

Jaspers have been revered by ancient peoples and civilizations throughout the world as sacred and powerful stones of protection, for both the physical and spiritual realm.
The name can be traced back in Arabic, Persian, Hebrew, Assyrian, Greek and Latin, and the virtues of Jaspers have been extolled throughout the ages by the most noted physicians, magicians, poets, scientists, lapidaries and scholars.
The term Jasper is currently restricted to opaque microcrystalline Quartz, though the ancient iaspis was a stone of considerable translucency, often compared to the Emerald and other green objects. The ancient Jaspers may have included stones which today would be classed as Chalcedony, and the emerald-like Jasper referenced in so many texts may have been more like the modern Chrysoprase.
Translucent Green Jasper is rare today as a single color and often of high quality, but along with the opaque variety, is more common in multi-colored or Rainbow Jaspers, Orbicular Jaspers, and as major components of specific stones such as Heliotrope or Bloodstone, Arizona Lizard Stone, and Rainforest Jasper. Green Jasper was equally credited throughout the centuries for driving away evil spirits and ghosts, harmful fantasies, and witchcraft. It was particularly protective against venomous creatures, kept one from drowning, and warded off sorrow.
It provided good health, made one amiable and brave, healed fever and edema, diseases of the stomach, lungs and chest, and increased fertility, aiding women throughout their pregnancy and childbirth.

Jasper water is soothing for the digestive system, and is particularly useful as a gem elixir because it does not over stimulate the body. It may be made by the indirect method, or by letting the stone soak in demineralized water overnight. Green Jasper is beneficial in staunching blood flow, particularly nosebleeds and menstrual flow, and assists in reducing hemorrhoids. It soothes epilepsy and gout, and may be used to treat the sensory loss of smell.
It helps one recognize thought patterns and fixations that have become irrational, and brings the courage needed to express and accept them in order to move forward.
All Jaspers connect to the Earth and may be placed on the Base Chakra to stabilize and energize the physical body. Laying it over each chakra in turn, will cleanse, boost and realign the chakras and aura, balancing yin and yang energies as well as aligning the physical, emotional and mental bodies with the etheric realm.
Green Jasper is particularly attuned to the Heart Chakra , located near the center of the breastbone. It regulates our interaction with the external world and controls what we embrace and what we resist. It gives us the balancing ability to be ourselves within the environment. When the Heart Chakra is out of balance we may feel either controlling or controlled in a relationship, and become critical of the little foibles of others. We may find ourselves having inappropriately strong emotional responses to everyday external stimuli.

They are ideal for grounding and centering at the beginning of a ritual, and ease the transition to a meditative state. Use Jasper for the first few minutes of any meditation, and then switch to a crystal or particular Jasper that is attuned to the intent of your session.
Green and Brown Jaspers were considered the most powerful for this purpose. Jasper has also been utilized for divining the future. Picture Jasper is especially conducive for dream work and visioning, and Black Jasper is an excellent scrying stone. The Divinatory meaning of Green Jasper: A good time for fertility, the time when a dream will start to grow.
If your birthday falls in any of the following periods, a Green Jasper can be a valuable conduit to your Guardian Angel. The table also provides the name of the Guardian Angel of those born in the time period. There are other Angels that are partial to Green Jasper. The table below gives you the information about them.

Jasper was a significant stone in nearly all religious and cultural histories throughout the world. In a Mesopotamian creation legend, the god Marduk Jupiter formed three heavens or spheres above the Earth, with the lower one being created from Jasper. On it he drew the constellations.
In Viking and German legends, the hilt of the magical sword of Siegfried, the dragon-slayer, was inlaid with Red Jasper to give him courage.
Red Jasper was also called the blood of Mother Earth among some Native North American tribes, and in ancient Egypt was linked with the fertilizing blood of Mother Isis. Jaspers were often used for carving texts on sacred amulets for placement on the bodies of the dead to insure safe passage into the afterlife.
