“…Tin granite can be porphyritic, seriate, or equigranular in texture, but all are light-colored peraluminous biotite granites, and all are small offshoots of large granodiorite-to-granite batholiths from which the tin granite evolved by fractional crystallization. The tin granites are found in stable cratonal regions and not in continental or oceanic arcs (Hudson and Arth, 1983). Fluorspar deposits associated with tin granites have a variety of geometries (veins; replacements; skarns at intrusive contacts; greisens in small, upward projections on the granite body's roof [that is, endogreisens in granitic cupolas]; and greisens in wall rocks of the granite [that is, exogreisens]).…”

“…(In peraluminous igneous rocks, molar Al 2 O 3 > (Na 2 O + K 2 O).) Tin granite is also a very specific type of granite (Tischendorf, 1978;Hudson and Arth, 1983). Tin granite can be porphyritic, seriate, or equigranular in texture, but all are light-colored peraluminous biotite granites, and all are small offshoots of large granodiorite-to-granite batholiths from which the tin granite evolved by fractional crystallization.…”

“…Likewise, the province of tin granites on the Seward Peninsula in Alaska (Hudson and Arth, 1983) might contain additional fluorspar skarn-and-greisen deposits similar to the Lost River deposits. Other areas of Alaska with tin greisen mineralization have been explored but with little attention paid to the associated fluorspar .…”

In the Erzgebirge two post-collisional Hercynian granitoid complexes are developed: an older one, monzogranitic, moderately specialized, Sri =0.7064-68, &TNd = -1.8 to -6.2, lg f0, < -13 f 1, Ig fHF/fH20 = -3.9 f 0.2, S-type, 340-325Ma in age, and a younger one, monzo-to albitegranitic, highly specialized in Li, Rb, Cs, Sn, and W, Sri disturbed by strong autometasomatic influences, ET,, = -3.8 to -6.0, lg f02 < -17 f 1, lg MF/fH,O = -3 f 0.3, I-type, 310-295 Ma. Postplutonic volcanics (rhyolite, rhyodacite, latite, kersantite-minette) in each case complete the magmatic sequences.Muscovite-wolframite-molybdenite-pyrite-quartz association is locally related to the older complex, but numerous centres of cassiterite-wolframite-zinnwaldite (or muscovite) deposits are related to the younger one. Both mineralizations are of orthomagmatic origin and underwent strong physicochemical control. Thus, the granites genetically related to the tin-free older association are conditioned by medium f0, but low fHF/fH,O, the tin-bearing younger association, in contrast, is controlled by low f0, coupled with high MF/fH20.Vertical compositional zonation in magma chambers caused enrichment of compatible elements such as Zn, Pb, Mg, Ca, Ba, Sr, in deeper parts of the chamber and their transition into residual solutions which then may form base metal mineralization as cross-cutting veins. Mineralization events last up to the Triassic. Probably elements in the later stages were derived either from deep-originated residual solutions or, increasingly, by leaching of specialized magmatites.
