Pitwik Mine

This place cannot be located with certainty.

Pitwik (Pitwak) is one of the mines around Lajuar Madan in Sar-e-sang and most of the better gem yellow or well-crystallized scapolites come from there (Dudley Blauwet, priv. comm. 2013). See:

The orthoclase pseudomorphs after marialite are sometimes blue. So far the blue has avoided identification. Please see:

Detailed Mineral List:

Formula: Na(AlSi3O8)
Habit: Crystalline to crude xls
Colour: white
Description: PXRD confirmed
Reference: John Attard (2014) Private Communication
Formula: CaMgSi2O6
Habit: crude prisms
Colour: greenish white
Fluorescence: none
Description: PXRD confirmed
Reference: John Attard (2014) Private Communication
Haüyne ?
Formula: (Na,K)3(Ca,Na)(Al3Si3O12)(SO4,S,Cl)
Colour: blue
Fluorescence: none
Description: Marialite pseudomorphs to blue: Lazurite?, sodalite? Hauyne? afghanite? or trace Fe impurities. see:
Reference: John Attard PXRD
Lazurite ?
Formula: Na6Ca2(Al6Si6O24)(SO4,S,S2,S3,Cl,OH)2
Colour: blue
Fluorescence: none
Description: Marialite pseudomorphs to blue: Lazurite?, sodalite? Hauyne? afghanite? or trace Fe impurities. see:
Reference: John Attard PXRD
Formula: Na4Al3Si9O24Cl
Habit: Tetragonal prisms, pyramids and pinacoid
Colour: white
Description: Marialite is the only confirmed (PXRD) scapolite and it Fluoresces bright yellow under long wave UV. All of these scapolites have altered partially or completely to orthoclase.
Formula: Ca4Al6Si6O24CO3
Colour: White
Fluorescence: Strong yellow
Description: Meionites and Meionites pseudomorphing to Lazurite. Probed by Bart Cannon, but incorrectly interpreted by Rob Woodside These Marialites have altered, some completely, some partially to Orthoclase. Surviving Marialite has a bright yellow long wave fluorescence.
Reference: Thames Valley Minerals Specimen, RWMW collection
Formula: K(AlSi3O8)
Habit: Excellent sharp scapolite xls altered to a cherty looking orthoclase
Colour: off white with iron staining
Description: Orthoclase (PXRD confirmed) pseudomorphs after excellent scapolite xls. The blue in these xls is either sodalite or lazurite
Reference: RWMW Collection
Habit: Tetragonal Prisms , pyramidal faces, and pinacoid
Colour: white grey, blue
Fluorescence: bright yellow if any marialite left
Description: Marialite is the only confirmed (PXRD) Scapolite from here. The surviving marialite is bright yellow under long wave UV. However, these scapolites are altering to Orthoclase which does not fluoresce. Some of these orthoclase pseudomorphs after scapolite are quite blue. Because this is from Sar-e-Sang, one immediately thinks this due to a blue feldspathoid. If this feldspathoid exists it is below the detection limits of PXRD and EDS. Apparently tiny Fe impurities can turn feldspar blue
Reference: TVM Specimen
Sodalite ?
Formula: Na4(Si3Al3)O12Cl
Description: Marialite pseudomorphs to orthoclase with blue: Lazurite?, sodalite? Hauyne? afghanite? or trace Fe impurities? see:
Reference: TVM Specimen
