Ström (1821) recognized it as a new mineral and suggested the name \u003Cem>wernerin\u003C\u002Fem>, after the German geologist, Abraham Gottlob Werner. But Berzelius (1821), who analysed the mineral, named it \u003Cem>achmit\u003C\u002Fem> after the Greek αχμη, spear point, due to the habit of the crystals. \r\n\r\nLater, in 1834, the priest and mineralogist Hans Morten Thrane Esmark found a new mineral on \u003Cl id='2489'>Låven, Langesundsfjorden, Norway\u003C\u002Fl> which was described and given the name \u003Cstrong>aegirine\u003C\u002Fstrong>, after Ægir (Aegir), the sea god in Norse mythology because the type location was along the sea shore (Berzelius 1835). Acmite and aegirine were first believed to be two separate species, one belonging to the amphiboles (acmite) and the other to the pyroxenes (aegirine). This was the case until 1871 when G. Tschermak put forward evidence that acmite and aegirine both belonged to the pyroxenes and are the same mineral. Acmite has been considered as a variety of aegirine (historically acmite had priority, so it should have been the other way around).","2025-12-11

The small tan needles on aegirine which can be seen in the gap between the two main albite crystals are lorenzenite, some apparently epitactic. (The lorenzenite has been verified via EDS. See \u003Ca rel=\"nofollow\" class=\"external autonumber\" href=\"https:\u002F\u002Fwww.mindat.org\u002Fphoto-842285.html\">[1]\u003C\u002Fa> for a better example and an EDS scan.) The pyrochlore is clearly “fuzzy” because it is encrusted by more pyrochlore of similar compositio. There are a very few \"naked\" crystals (not on this specimen) that also appear to be yellowish. However, some of the crust can be removed with HCl, suggesting that it is cemented by calcite.\u003Cbr>Update April 2017: Quick and dirty EDS of uncoated samples on matrix seemed to show very high Ta for both the \"crust\" and the \"naked\" crystals (after removal of crust). For the \"naked\" crystals, peak heights for Ta > Nb were oberved, which would suggest \"microlite group\". However, consultation with a mineralogist very familiar with \"pyrochlore\" at MSH, strongly suggests that the \"Ta\" peaks are really \"Si\", and that this is just \"pyrochlore\" with lots of Si. According to the expert, high levels of Si have been found repeatedly in MSH pyrochlores. It is not know if this is because the pyrochlore is metamict or because Si has actually been incorporated into the pyrochlore structure (as has been suggested by some.)\u003Cbr>See the Analysis \"photos\" Feb 2018: The two \"pyrochlore\" species now confirmed at MSH are fluornatropyrochlore and fluorcalciopyrochlore, assuming that this too is a \"fluor-pyrochlore\" (EDS can't tell), it seems more likely that it is fluorcalciopyrochlore than fluornatropyrochlore. However, Na is detected with difficulty and its seeming near absence in the scans could be misleading. Nonetheless, I have tentatively changed the caption from \"pyrochlore group\" to \"fluorcalciopyrochlore\".

mineral now called **aegirine** entered the literature twice, under two different names, before anyone realised the two specimens were one species.\n\nThe first description came in 1821. The Norwegian mineralogist P. H. Ström examined a brown, pointed mineral from Rundemyr, in Øvre Eiker. The same locality had been noted, very briefly, in 1784, where the material was described as a kind of \"crystallised hornstone\" embedded in quartz[1]. Ström recognised it as a new species and proposed naming it *wernerin*, after the German geologist Abraham Gottlob Werner[1]. The Swedish chemist Jöns Jacob Berzelius carried out the analysis that same year. He overruled the proposal and chose *achmit* instead — from the Greek *akmē*, point, in reference to the sharply pointed crystals[1]. The name reached English-language mineralogy as *acmite*.\n\nA second discovery followed in 1834. The priest and mineralogist Hans Morten Thrane Esmark found another unfamiliar mineral on the island of Låven, in the Langesundsfjord on the Norwegian coast[2]. Berzelius described and named it the following year, in 1835. He called it *aegirine*, after Ægir, the Norse god of the sea, because the type locality lay along the seashore[2].\n\nFor half a century, mineralogists treated acmite and aegirine as two distinct species. They even placed them in two different families — acmite among the **amphiboles**, aegirine among the **pyroxenes**, the two big groups of dark silicate minerals that build most volcanic and intrusive rocks[1]. The Austrian mineralogist Gustav Tschermak settled the question in 1871. His analyses showed that both samples belonged to the pyroxene group, and were the same mineral[1]. *Acmite*, as the older name, should by convention have taken precedence. But *aegirine* had become the more widely used term and stayed as the species name. *Acmite* survives as a synonym, today usually reserved for the pure sodium-iron end-member of the series.","claude-opus-4-7","1.7.0",{"markdown":1424,"model_version":1421,"prompt_version":1422,"reviewed_at":11},"Aegirine has no industrial application. The mineral is too scattered, and the rocks that carry it are too specialised, to support mining for any commercial product. What demand exists is from petrologists who study the rocks, and from collectors who keep the crystals.\n\nFor geologists, aegirine is a diagnostic mineral of **peralkaline magmas** — molten rocks unusually rich in sodium and potassium relative to aluminium. It appears almost exclusively in such rocks: nepheline syenites, syenite pegmatites, carbonatites, and a handful of metamorphic settings[1]. Finding aegirine in a thin section of a rock — the wafer-thin slice geologists view under a microscope — is therefore a strong clue about the chemistry of the magma that produced it.\n\nThe collector market is the only domain where individual aegirine crystals are sought for their own sake. A few localities dominate the trade. Mont Saint-Hilaire in Quebec, Canada is an alkaline complex famous among mineralogists for the sheer variety of its species. It yields the largest aegirines — prismatic, lustrous black, up to about 30 centimetres long[2]. They occur in pegmatites alongside pink eudialyte, white gonnardite, and colourless natrolite[2]. The Kola Peninsula in Russia produces similar associations on an even larger geological scale, and Magnet Cove in Arkansas adds a smaller classic American occurrence[1]. Notable specimens have also been recorded from Greenland, Scotland, Kenya, and Nigeria[1].\n\nA few aegirines reach the gem trade as faceted stones, but the material is too dark and too scarce to compete with mainstream gem species, and it remains a curiosity rather than a working jewellery stone[3]."]
