Kokscha Valley; Koksha Valley


The Kokcha River (Persian: رودخانه کوکچه‎) is located in northeastern Afghanistan. A tributary of the Panj river, it flows through three districts* in Badakhshan Province in the Hindu Kush. The city of Feyzabad lies along the Kokcha. Near the village of Artin Jelow there is a bridge over the river.

* Strictly speaking it continues, near the village of Baharak, where the Warduj river meets the Kokcha. The Kokcha river then flows east, going around the northern border of Argo District and passing Feyzabad. Finally, the Kokcha enters Takhar Province, flows around the southern border of Rustaq District, and ends at the Amu Darya by Ai-Khanoum.

The Kokcha River valley is known for its lapis lazuli mining in Badakshan province. Found in marble, these deposits in the mines of Sar-e-Sang were being worked as early as the 3rd millennium BC and the Kokcha River valley is considered one of the world's leading areas of mining this reserve. The valley was the source of lapis lazuli for the ancient Egyptian and Mesopotamian civilizations, as well as the later Greek and Roman. During the height of the Indus valley civilization about 2000 BC, the Harappan colony now known as Shortugai was established near the lapis mines.
More recently, during the 1980s conflict with the USSR, Afghanistan's resistance fighters disassembled unexploded Soviet land mines and ordnance and used the scavenged explosive to help mine lapis lazuli along the Kokcha river to further fund their resistance efforts.

The metamorphic deposits within the Kokcha valley include marbles with exceptional specimens of lazurite, sodalite, etc.

A hackmanite occurrence produces exceptional examples of this variety, but details as to the exact location they occur in, are as yet unavailable at Mindat. People who have visited the location and who have definitive information are invited to provide input. Many localities appear on labels, as the commercial world has endeavoured to provide specific locality information instead of providing genuine information.

And Hazrat Saeed appears to be the only Sapphire source in Koksha Valley."
'Fayalite-Forsterite Series'
Fluorapatite
Formula: Ca5(PO4)3F
Fluor-dravite ?
Formula: NaMg3Al6(Si6O18)(BO3)3(OH)3F
Description: Analyses by several different researchers (see discussion of the deep blue "fluor-dravite" composition at https://www.mindat.org/mesg-506047.html ) suggest little F is present in these samples, and so the tourmalines fall along the dravite/oxy-dravite/uvite nomenclature boundaries. Specific references with compositional data include: https://www.gia.edu/doc/Gems-Gemology-Winter-2016v4.pdf and https://www.rockptx.com/fkm-251-to-fkm-275/#FKM-268 .

Graphite
Formula: C
Grossular
Formula: Ca3Al2(SiO4)3
Colour: light red brown
Fluorescence: none
Description: Occurs in white calcite with pine green diopside. Analysed by John Attard
Gypsum
Formula: CaSO4 · 2H2O
Haüyne
Formula: Na3Ca(Si3Al3)O12(SO4)
Habit: Large dodecahedra to several cm
Colour: Dark blue , blue, dark green, light green
Fluorescence: Orangey brown in long-wave UV light.
Description: The blue haüyne has a cell edge of 9.08 A (Fernando Camera, priv. comm. 2013) and the green one 9.05 A (Fernando Camera, priv. comm. 2010). Both have similar modulated structures. A few dozen specimens of green haüyne were recovered. Dudley Blauwet (2008) has photos of the material in situ. Fewer darker green haüynes later emerged. PXRD at the Royal Ontario museum gave Lazurite-C with gypsum for the early green material (Malcolm Back, priv. comm. 2009). Fernando Camara (2010) found it has a cubic cell edge of 9.05 A and a 45 A modulated structure. A Raman analysis at the University of Arizona gave both haüyne and lazurite for the blue hauyne. The problem is that no natural sulfide-dominant lazurite has ever been observed. Such material can be synthesized but is unstable. All 'lazurite' specimens is actually sulfate-dominant haüyne. The specious argument to call some PXRD-analyse samples lazurite stems from the observation that sulfide is smaller than sulfate and so haüynes with small unit cells should have more sulfide, but there is never enough to be sulfide dominant. Furthemore, contents of impurity elements such a K influence the cell parameter.
Hedenbergite
Formula: CaFe2+Si2O6
Hematite
Formula: Fe2O3
Hydroxylclinohumite
Formula: Mg9(SiO4)4(OH)2
'K Feldspar'

Lazurite
Formula: Na7Ca(Al6Si6O24)(SO4)(S3) · H2O
Habit: Rhombic dodecahedrons modified with cube and octahedral forms
Colour: Ultramarine to midnight blue
Fluorescence: none,
Description: Since all 'lazurites' are sulfide rich hauynes, we restrict the name Lazurite to the blue mineral in Lapis Lazuli, which is opaque, non fluorescent, ultramarine to midnight blue with a bright blue streak
Magnetite
Formula: Fe2+Fe3+2O4
Marialite
Formula: Na4Al3Si9O24Cl

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.
'Mica Group'
Microcline
Formula: K(AlSi3O8)
Molybdenite
Formula: MoS2
Monticellite
Formula: CaMg(SiO4)
Muscovite
Formula: KAl2(AlSi3O10)(OH)2
Description: No data. Possibly phlogopite.
Native Sulphur
Formula: S8
Nepheline
Formula: Na3K(Al4Si4O16)
Habit: Hexagonal prisms with small pyramids and large pinacoid
Colour: grey white
Fluorescence: none
Description: The electric blue colour is from Nosean flecks in a clear sodalite coating the large nephelines
Nosean
Formula: Na8(Al6Si6O24)(SO4) · H2O
Habit: Exsolution specs.
Colour: electric blue
Fluorescence: none
Description: The x-rays suggest Nosean, Lazurite or Hauyne, but EDS shows the blue specs to be nosean (contains no Ca like Lazurite or Hauyne) These 0.1 micron specs are at the current limit of single xl XRD. The nosean is exsolved from a 100 micron layer of clear sodalite. This exsolution has been observed in synthetic materials (Van Peteghen et al 1963). This clear sodalite coats and is not in epitaxi with cm sized greasy grey nepheline xls.
Omphacite
Formula: (NaaCabFe2+cMgd)(AleFe3+fFe2+gMgh)Si2O6
Orthoclase
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
References:
Pargasite
Formula: NaCa2(Mg4Al)(Si6Al2)O22(OH)2
Habit: Terminated prisms to several cm
Colour: Brown
Fluorescence: none
Description: Frank Hawthorne identified this pargasite. Green "colour change lazurites" (green Hauyne) being replaced by zeolite occur with large pargasite xls. Thus the pargasite has been assigned to this locality.
Phlogopite
Formula: KMg3(AlSi3O10)(OH)2
Localities: Reported from at least 8 localities in this region.
'Plagioclase'
Formula: (Na,Ca)[(Si,Al)AlSi2]O8
Potassic-fluoro-richterite ?
Formula: K(CaNa)Mg5(Si8O22)F2
Description: A Rob Lavisnky specimen from "Kokcha Valley". Work done on these amphoiboles indicates that they are K and F rich richterites, but generally not meeting the criteria for potassic-richterite, fluoro-richterite or ptassic-fluoro-richterite. This does not preclude the occurrence of potassic-fluoro-richterite at Sar-e Sang.
Pyrite
Formula: FeS2
Localities: Reported from at least 8 localities in this region.
Pyrrhotite
Formula: Fe1-xS
Description: https://www.mindat.org/mesg-609539.html
Quartz
Formula: SiO2
Richterite
Formula: Na(CaNa)Mg5(Si8O22)(OH)2
Habit: Terminated prisms
Colour: colourless to yellow brown
Fluorescence: none
Description: Initially identified as Winchite the gemmy yellow amphibole is Potassian Fluorian Richterite ( Frank Hawthorne Analysis)
Sapphirine
Formula: Mg4(Mg3Al9)O4[Si3Al9O36]
'Scapolite'
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 http://www.mindat.org/mesg-105-318134.html
Sodalite
Formula: Na4(Si3Al3)O12Cl
Localities: Reported from at least 7 localities in this region.
Habit: Dodecahedra to 6 cm
Colour: The colours range from colourless , to grey, to yellow, to green, to lilac, to purple. The colorless to lilac and purple are photochromic.
Fluorescence: The best fluorescence is under long wave. The grey sodalite has the typical yellow disulfide fluorescence under long wave.
Description: The largest and best sodalite xls to 5 cm were found here
Sodalite var. Hackmanite
Formula: Na8Al6Si6O24Cl2
Habit: Crude to sharp dodecahedra with trapezohedral modifications
Colour: clear, white, grey, green, lilac, purple
Fluorescence: In Long Wave UV: yellow orange, pink, white
Description: These are some of the best Hackmanites ever found and show a variety of optical properties, such as darkening in the dark after bleaching in Yellow light, Reversible Photochromism (tenebrescence)with UV irradiation and yellow light. The grey sodalites contain significant K.
