Such tachylite <a href="/wiki/Volcanic_bomb" title="Volcanic bomb">volcanic bombs</a> and scoria are frequent in <a href="/wiki/Iceland" title="Iceland">Iceland</a>, <a href="/wiki/Auvergne_(region)" class="mw-redirect" title="Auvergne (region)">Auvergne</a>, <a href="/wiki/Stromboli" title="Stromboli">Stromboli</a> and <a href="/wiki/Mount_Etna" title="Mount Etna">Etna</a>, and are very common also in the ash beds or <a href="/wiki/Tuff" title="Tuff">tuffs</a> of older date, such as occur in Skye, Midlothian and Fife, Derbyshire, and elsewhere.

These tachylite fragments, which are usually much decomposed by the oxidation and hydration of their ferrous compounds, have taken on a dark red color. This altered basic glass is known as "<a href="/wiki/Palagonite" title="Palagonite">palagonite</a>"; concentric bands of it often surround kernels of unaltered tachylite, and are so soft that they are easily cut with a knife. In the palagonite the <a href="/wiki/Mineral" title="Mineral">minerals</a> are also decomposed and are represented only by pseudomorphs. The fresh tachylite glass, however, often contains lozenge-shaped crystals of plagioclase feldspar and small prisms of <a href="/wiki/Augite" title="Augite">augite</a> and olivine, but all these minerals very frequently occur mainly as microlites or as skeletal growths with sharply-pointed corners or ramifying processes. Palagonite tuffs are found also among the older volcanic rocks. In Iceland a broad stretch of these rocks, described as "the palagonite formation," is said to cross the island from south-west to north-east. Some of these tuffs are <a href="/wiki/Fossil" title="Fossil">fossiliferous</a>; others are intercalated with <a href="/wiki/Glacier" title="Glacier">glacial</a> deposits.

Such edges may be as little as a millimetre thick. It merges internally into crystalline basalt.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p><p>In the <a href="/wiki/Hawaii" title="Hawaii">Hawaiian</a> Islands, however, the volcanoes have poured out vast floods of black basalt, containing feldspar, augite, olivine, and <a href="/wiki/Iron" title="Iron">iron</a> <a href="/wiki/Ore" title="Ore">ores</a> in a black glassy base. They are highly liquid when discharged, and the rapid cooling that ensues on their emergence to the air prevents crystallization taking place completely. Many of them are spongy or vesicular, and their upper surfaces are often exceedingly rough and jagged, while at other times they assume rounded wave-like forms on solidification. Great <a href="/wiki/Cave" title="Cave">caves</a> are found where the crust has solidified and the liquid interior has subsequently flowed away, and <a href="/wiki/Stalactite" title="Stalactite">stalactites</a> and <a href="/wiki/Stalagmite" title="Stalagmite">stalagmites</a> of black tachylite adorn the roofs and floors. On section these growths show usually a central cavity enclosed by walls of dark brown glass in which skeletons and microliths of augite, olivine and feldspar lie imbedded. From the crater of Mt. <a href="/wiki/Kilauea" class="mw-redirect" title="Kilauea">Kilauea</a>, thin clouds of steam rise constantly, and as the bubbles of vapor are liberated from the molten rock they carry into the air with them thin fibers of basalt that solidify at once and assume the form of tachylite threads. Under the microscope they prove to be nearly completely glassy with small circular air vesicles sometimes drawn out to long tubes. Only in the Hawaiian Islands are glassy basaltic lavas of this kind at all common.<sup id="cite_ref-FOOTNOTEFlett1911344_1-3" class="reference"><a href="#cite_note-FOOTNOTEFlett1911344-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> A small outcrop at <a href="/wiki/Tachylite_in_Victorian_archaeological_sites" title="Tachylite in Victorian archaeological sites">Spring Hill</a> in <a href="/wiki/Victoria,_Australia" class="mw-redirect" title="Victoria, Australia">Victoria, Australia</a><sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> has tachylite which has been exploited as a material for making Aboriginal flaked stone implements.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Dike_and_sill_sources">Dike and sill sources</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Tachylite&action=edit&section=4" title="Edit section: Dike and sill sources"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>A third mode of occurrence of tachylite is as the margins and thin offshoots of <a href="/wiki/Dike_(geology)" title="Dike (geology)">dikes</a> or <a href="/wiki/Sill_(geology)" title="Sill (geology)">sills</a> of basalt and <a href="/wiki/Diabase" title="Diabase">diabase</a>. They are sometimes only a fraction of an inch in thickness, resembling a thin layer of pitch or tar on the edge of a crystalline diabase dike, but veins several inches thick are sometimes found. In these situations tachylite is rarely vesicular, but it often shows very pronounced fluxion banding accentuated by the presence of rows of spherulites that are visible as dark brown rounded spots. The spherulites have a distinct radiate structure and sometimes exhibit zones of varying color. The non-spherulitic glassy portion is sometimes perlitic, and these rocks are always brittle. Common crystals are <a href="/wiki/Olivine" title="Olivine">olivine</a>, <a href="/wiki/Augite" title="Augite">augite</a> and <a href="/wiki/Feldspar" title="Feldspar">feldspar</a>, with swarms of minute dusty black grains of <a href="/wiki/Magnetite" title="Magnetite">magnetite</a>. At the extreme edges the glass is often perfectly free from crystalline products, but it merges rapidly into the ordinary crystalline diabase, which in a very short distance may contain no vitreous base whatever. The spherulites may form the greater part of the mass, they may be a quarter of an inch in diameter and are occasionally much larger than this. These coarsely spherulitic rocks pass over into the variolites by increasing coarseness in the fibers of their spherulites, which soon become recognizable as needles of feldspar or feathery growths of augite. The ultimate product of decomposition in this case also is a red palagonitic substance, but owing to the absence of steam cavities the tachylite selvages of dikes are more often found in a fresh state than the basic lapilli in ash-beds. Many occurrences of basaltic <a href="/wiki/Pitchstone" title="Pitchstone">pitchstones</a> have been reported from Skye, Mull, and the western part of <a href="/wiki/Scotland" title="Scotland">Scotland</a>; they are found also in connection with the <a href="/wiki/Intrusion_(geology)" class="mw-redirect" title="Intrusion (geology)">intrusive</a> diabase sills in the north of <a href="/wiki/England" title="England">England</a> and the center of Scotland.
