Omtrent 200 m nord for Feset I bruddet ligger et annet feltspatbrudd som i følge O. Andersen har levert store mengder felttspat. I 1926 ble det f.eks. utvunnet ca 330 tonn feltspat. Bruddet har form av en ca 10 m dyp rund synk med 30 m's diameter. Pegmatitten består av en uregelmessig blanding som holder overveiende kali-natronfeltspat i stolper på ca 1/2 m's størrelse, atskillig kvarts, betydelig mindre mengder kalk-natronfeltspat, litt skriftgranitt, muskovitt i små flak og litt biotitt.. Kali-natronfeltspaten er en rødlig variant med omkring 2% Na2O og 13% K2O; svarende til 15% natronfeltspat og 76% kalifeltspat. Kalk-natronfeltspaten har omkring 27% kalifeltpat og 73% natronfeltspat. |

Abstract: | |
The present publication is a description, in non-technical language, of the properties, geological mode of occurrences, exploitation, and uses of feldspar with special reference to the Norwegian feldspar industry. Systematic descriptions of commercial deposits are reserved for a future publication to be issued as no. 128b of the present series. Chapter 1 contains a general description of the mineralogical, chemical, and physical properties of the various species of the feldspar group. - Table I gives the theoretical chemical composition of mixture of potash feldspar and soda feldspar for intervals of 10 pct. by weight. - Table 2 gives the corresponding figures for mixtures of soda feldspar and lime feldspar. - Table 3 contains a few examples of chemical analyses of feldspar from Norwegian occurrences. The analyses, of which No.s 1-5 are new, represent selected, "pure" feldspar. No.s 1, 2 and 3 are commercial "potash feldspars" from granite pegmatites, No. 4 a soda-potash feldspar from syenite pegmatite, and No. 5 a soda feldspar of commercial quality from a pyroxene bearing granite pegmatite. No.s 6 and 7 are old analyses respectively of oligoclase from granite pegmatite and labradorite from anorthosite. - Table 4 contains multiplication factors for the recalculation of feldspar analyses. |
