6 FAQs about [Jinchuan open pit rock drill]

How deep is the Jinchuan intrusion?

The Jinchuan intrusion was formed by the injection of high yield-strength, relatively viscous, high-density olivine- and sulphide-laden mushes from a depth estimated to be >4 km into nearby planar fractures/faults.

Where is the Jinchuan ultramafic intrusion located?

The Jinchuan ultramafic intrusion, which hosts a nickel-copper-PGE deposit, is located at 38°28′18″N, 102°10′59″E, some 300 km NNW of Lanzhou and 1200 km to the west of Beijing, in the city of Jinchang, north-central Gansu Province, China.

How did the Jinchuan deposit form?

The Jinchuan deposit formed at a depth of over 4 km when sulphide-rich magma passed through the structure and settled as cumulus deposits to create this intrusion. The resultant intrusion contains disseminated and net-textured sulphides in sulphide-dunite cores within a larger lherzolite sill complex.

How did the Longshoushan uplift affect the Jinchuan deposit?

The Longshoushan Uplift, an elongate, downward tapering faulted wedge, was uplifted by over 4 km during the Cenozoic shortening to expose the Jinchuan deposit in a window penetrating younger cover rocks. During this same event, the intrusion was tilted and fragmented into four structural segments.

What is the Jinchuan intrusion?

The Jinchuan intrusion is a 6500 m long and a few to 500 m wide geological feature that dips at 50° to 80°SW. It is composed of dunite, lherzolite, and pyroxenite, and has an indicated crystallisation age of 827 ± 8 Ma (U-Pb SHRIMP dating of zircon and baddeleyite; Li et al., 2004, Li et al., 2005).

Where is Jinchuan Group located?
