Volcano Haleakalā Ash Raw Minerals Lapilli Pumice Lava Bombs Stones Rocks Collecting

Volcanic Ash sample Raw Minerals Lapilli Pumice Lava Bombs Stones Rocks for Collection.
Rare specimen of Volcanic Sand erupted from the Haleakalā (East Maui) Volcan, collected from Ka'uiki Head Mountain. Coarse or medium grained.

Volcanic ash consists of small tephra, which are bits of pulverized rock and glass created by volcanic eruptions, less than 2 millimetres (0.1 inch) in diameter . Ash is created when the usually violent nature of an eruption involving steam results in the magma and solid rock surrounding the vent being torn into particles of clay to sand size.
Every ash samples is labelled and bagged in a vial with cap (mm 44 x 10), so thay can easily be removed if required for study under a microscope.
As with all volcanic ash, the material should be handled with care and not inhaled.


The Haleakalā volcano ("house of the sun") is the main volcano on the island of Maui, in the Hawaiian archipelago.
Also known as East Maui, it is a large shield volcano, which occupies more than 75% of the Hawaiian island.
The western 25% of the island is formed by another volcano, Mauna Kahalawai, also called "West Maui Mountains".
The summit of Haleakalā is located at 3.055 m. From the top you can see a deep depression of about 11.25 km wide, 3.2 km wide and almost 800 m deep. The surrounding walls are steep and the interior mostly look bleak with a handful of volcanic cones.
In Hawaiian folklore, the depression (crater) of the Haleakalā was the home of the grandmother of the demigod Māui. According to legend, Maui's grandmother helped him catch the sun and force him to slow down his journey across the sky to lengthen the day.
Haleakala has produced numerous eruptions over the past 30,000 years, including the last 500 years. This volcanic activity took place along two rift zones, which continue beneath the ocean beyond the eastern coast of Maui, making the rift zone one of the longest in the Hawaiian islands chain.
Until recently, the East Maui volcano was thought to have broken out for the first time around 1790, largely based on comparisons of maps made during the travels of La Perouse and George Vancouver. Recent tests of advanced dating, however, have shown that the last eruption is more likely to have occurred in the seventeenth century.
Contrary to popular belief, the "crater" of Haleakalā is not of volcanic origin, nor can it be precisely called a caldera (which is formed when the top of a volcano collapses to form a depression). Scientists believe that the "crater" of Haleakalā was formed when the rocky walls of two large erosive valleys merged at the top of the volcano.
Haleakala has erupted three times in the last 900 years. By way of comparison, both Mauna Loa and Kilauea have erupted more than a dozen times each over the past 90 years. Its dangerousness is therefore, reasonably, to be considered rather high.

Available on our website, besides ashes, pumice and bombs, also various volcanic rocks, such as Apache Teardrops, sulfur, obsidian, tuff, crystal chalk, etc.
