The water of crystallization is readily expelled by heat, with modification of the optical characters of the crystals.
Analcite usually occurs, associated with other zeolitic minerals, lining amygdaloidal cavities in basic volcanic rocks such as basalt and melaphyre, and especially in such as have undergone alteration by weathering; the Tertiary basalts of the north of Ireland frequently contain cavities lined with small brilliant crystals of analcite.
Euthallite is a compact, greenish analcite, produced by the alteration of elaeolite at various localities in the Langesund-f jord in southern Norway.

 Analcite - Wikipedia, the free encyclopedia
Analcite or analcime (from the Greek analkimos - "weak") is a white, grey, or colourless tectosilicate mineral.
Analcite is usually classified as a zeolite mineral, but structurally and chemically it is more similar to the feldspathoids.
Analcite occurs as a primary mineral in analcme basalt and other alkaline igneous rocks.

 Shiant Isles Geology Paper (Walker 1929) Page 3
Analcite, besides occurring as a replace­ment product of plagioclase, is, as one might expect, quite abundant interstitially, the usual proportion being about 8 per cent., and it is generally unaltered.
Apart from the olivine and analcite, the proportion in which the various minerals occur is the same as in the analcite-dolerite.
A large crystal of titanaugite on the left of the field is penetrated sub-optically by laths of partly analcitized         plagioclase.  Ilmenite is conspicuous near the top and bottom of the field, and a crescentic area of analcite is equally prominent on the right.       X 13.

 THERAMENES - LoveToKnow Article on THERAMENES
By decomposition the nepheline yields zeolites such as natrolite and analcite.
Very close to the theralites is a series of rock types known as the teschenites (from Teschen in Moravia).
Instead of nepheline these rocks usually contain analcite, and from their microscopic characters it is by no means likely that the analcite is secondary after nepheline in this case; it appears, in fact, to be either primary or of pneumatolytic origin.

Analcite is a common zeolite usually forming masses of trapezohedral crystals lining cavities in the basalt.
Sprays with crystals up to 1cm in length occur and may be associated with either analcite or phillipsite and chabazite.
Not enough material has been studied to determine a complete paragenetic sequence, however, observations show that analcite, phillipsite and the phacolitic form of chabazite appear to have formed early, followed by natrolite/thomsonite, then calcite, and as a late stage, the rhombohedral form of chabazite.

Among the zeolites and related minerals found were: stilbite, laumontite, gmelinite, analcite, natrolite, apophyllite, pectolite and datolite, and of common occurrence with these were quartz, calcite, pyrite, chalcopyrite, sphalerite and diabantite.
ANALCITE: One of the most striking minerals of the zeolite group is analcite.
Remarkably fine specimens were found, consisting of nearly transparent colorless crystals, of ideal symmetry, embedded in a matrix of beautiful pale green datolite crystals, some of the latter showing small crystals of datolite implanted on the larger ones, evidently a second generation (Plate 12, Fig.

They would define the monchiquites as rocks consisting of olivine, augite and analcite; others regard the analcite as secondary, and consider the base as essentially glassy.

Analcite (or analcime) is a minor constituent of a variety of igneous rocks, but is most commonly found in the midalkaline and alkaline rocks.
It may crystallise as a late-forming mineral in basalts, dolerites, trachybasalts, trachytes and phonolites.

The pozzolanic activity of two volcanic tuffs (Rhenish Trass) and the impact breccia Suevite (Bavarian Trass) were studied experimentally.
Analcite, phillipsite and smectite present in the pozzolanas were investigated seperately.
Only the tuff rich in phillipsite shows improved pozzolanic properties after heat treatment at 500°C. In contrast to analcite, phillipsite can be activated by calcination.

There is some relict analcite left (right photo) along with the copper and it appears to have been pseudomorphed or at least highly altered by copious fluid movement.
There was a footwall vein parallel to the main Kearsarge Lode that ran for thousands of feet through virtually all of the major mines in the Houghton County area that was wonderful to collect from as it was nearly always crystallized with copper casts after analcite or copper crystals and sometimes just fantastic sculptural forms.
Analcites are typically associated with fissure mines but they were occasionally found in areas of highly mineralized amygdaloids as well.

The composition is on the whole very homogeneous with under saturated alkali basalts with microlites of augite, feldspars, titanium-magnetite, analcite and leucite at the heart of a brownish glass.
For the technically minded the groundmass is characteristic of analcite-basanite (alkali feldspars, biotite, analcite and nepheline as an accessory mineral).

 AnalcimebyErin
Analcime, sometimes known as analcite, analcidite, or analzim, is a unique mineral named by the Greeks in 1801.
It was given the name analkis, meaning weak, for its unusual ability to generate a small or weak electrical charge when rubbed.
Although a member of the zeolite group, it is sometimes placed in the feldspathoid group because of the similarity of occurrences and chemical composition.

The presence of analcite and the resorption of olivine in the globules indicate an additional diffuse enrichment of fluids.
Increased alkali contents in the globules result in a reduction of melt temperature relative to the host.
Additionally, crystallization of analcite and recrystallization of the glass leads to the formation of radially orientated microfissures which are the main feature of the basaltic sunburn.
