Late Triassic mafic-ultramafic complex, intruded on the south side of the east-west trending Hongshila-Damiao deep fault into Archean metamorphic rocks in the northern margin of the North China Craton. The complex is concentrically zoned: a chromite-bearing core of serpentinized dunite is subsequently surrounded by wehrlite, diopside pyroxenite and minor amphibolite in its rim. The chromite bodies consist of veinlets and disseminations, rarely of masses. The ore minerals grade into the host rock.
Notes:
(1) In earlier Chinese references on platinum group minerals, this locality was referred to as "Gao District", derived from the first syllable of "Gaositai", and later as "Gaotai village". The latter however does not appear to exist.
(2) The grid reference is centered on the opencast workings in the western part of the deposit.

| ⓘ 'Amphibole Supergroup' Formula: AB2C5(T8O22)W2 |
| ⓘ Bowieite Formula: Rh2S3 Description: Reported by Chen (1981) as "sulrhodite" which was then believed to be a new mineral, but later was shown to be the same mineral as bowieite. |

| ⓘ Chengdeite (TL) Formula: Ir3Fe Type Locality: Description: Note on the list of associated minerals: The English abstract of the paper by Yu (1995) reports more minerals than listed here, but it has the associates from this locality and the placer occurrences lumped together. The Chinese text lists individual parageneses for both occurrences and states that most of the minerals were only found in the placers. |
