Remarks

Reported as among the oldest rocks of the Nanga Parbat-Haramosh massif and interpreted as Indian-plate Precambrian basement; its precise crystallization age is not well constrained and Palaeoproterozoic (Early Proterozoic) assignments remain debated.

Age & correlation (1)

Kazmi & Jan (1997): the curated 'Early Proterozoic (2600–2200 Ma)' age is not directly supported here — as the cover to the ~1850 Ma Iskere Orthogneiss and a proposed correlative of the Late Proterozoic Tanawal Formation, the Shingus Gneiss protolith is more plausibly (Late?) Proterozoic. Flagged for reconciliation.

Kazmi, A.H. & Jan, M.Q. (1997)

Lithology (1)

Kazmi & Jan (1997), after Madin (1986, 1989): the Shingus Gneiss is an amphibolite-grade pelitic and psammitic paragneiss forming the lower part of the Nanga Parbat Group in the Nanga Parbat–Haramosh Massif. It is interlayered by ~500 Ma orthogneisses, and its contact with the overlying Iskere Orthogneiss is sheared and marked by sillimanite-bearing mylonites; the Baroluma Fault separates it from the Haramosh Schist to the south and the Majupah Fault from island-arc gabbro/ultramafics.

Geological significance (2)

Corroborating reference: the Shingus Gneiss is also documented in Kazmi & Jan (1997), 'Geology and Tectonics of Pakistan' (reviewer-confirmed), added alongside the GSP lexicon (Malkani & Mahmood 2017) record.

Kazmi, A.H. & Jan, M.Q. (1997)
Kazmi & Jan (1997): Treloar et al. (1991b) regard the Shingus Gneiss as the metasedimentary cover to the Iskere Orthogneiss and correlate it with the Tanawal Formation–Mansehra Granite sequence of the Hazara region, whereas Madin et al. (1989) place the Shingus Paragneiss as the structurally lowest unit of the massif (below the Iskere Orthogneiss and the Haramosh Schist) — the superposition remains debated owing to pervasive fault contacts.
