Quartz Ridge Gombak is a geosite in Taman Melawati that is part of the Gombak-Hulu Langat Geopark and has scientific, recreational, and aesthetic historical value. The Quartz Ridge Gombak is around 82 million years old. Quartz gems are formed along the Kuala Lumpur-Endau Fault, which is the main fault. Ridge occurrences caused by hydrothermal dissolution and fault filling in the Late Cretaceous are compatible with the history of ridge formation.
This ridge was developed in the earth as a crust and was exposed to the surface during a period of basin filling in the Paleocene-Holocene period due to intense weathering. The hardness of the quartz crystal in comparison to the granite rock that becomes soil emphasises the shape of the ridge. This geosite is also of great ecological significance because it contains the longest quartz ridge record in Malaysia and the region, stretching 14 kilometres.
This is Gombak-Hulu Langat Geopark’s geosite (G23)
