A Neoproterozoic granite-rhyolite igneous complex exposed around the Karunjhar Hills at Nagarparkar, SE Sindh - the Pakistani extension of the Malani Igneous Suite of Rajasthan.

Exposed in Nagarparkar area of southeastern Sindh. Part of the Malani Igneous Suite extending from Rajasthan. Represents major Neoproterozoic felsic magmatism.

Remarks

Records major Neoproterozoic A-type, largely anorogenic felsic magmatism of the Malani Igneous Suite (a Neoproterozoic silicic large igneous province) linked to Rodinia; U-Pb zircon ages from the complex span roughly the late Tonian (~740-880 Ma).
