Abstract— More than 100 m thick of slate is exposed at an earth quarry of Bukit Tuntung, Pauh, Perlis. The slate comprises quartz, chlorite and muscovite and shows very distinct cleavages. No fossils were discovered from the slate. It is overlain by the bedded chert which is considered as the lowermost part of the Kubang Pasu Formation. The chert contains Early Carboniferous Radiolarians i.e. Stigmosphaerostylus variospina (Won) and Callela hexactina Won. It can be interpreted that the slate is older than Early Carboniferous. No limestone of the Setul Formation was observed in the vicinity of Pauh. It is therefore, more appropriate to assign the slate as the topmost of Mahang Formation.

Abstrak— Lebih daripada 100 m tebal sabak tersingkap di kuari tanah di Bukit Tuntung, Pauh, Perlis. Sabak terdiri daripada kuarza, klorit dan muskovit dan menunjukkan ira yang sangat jelas. Tiada fosil ditemui dalam batuan sabak. Sabak dilapisi di atasnya oleh batuan rijang yang dianggap sebagai bahagian paling bawah daripada Formasi Kubang Pasu. Rijang ini mengandungi radiolaria berusia Karbon Awal seperti Stigmosphaerostylus variospina (Won) dan Callela hexactina Won. Sabak ditafsirkan lebih tua daripada Karbon Awal. Tiada batu kapur Formasi Setul ditemui berdekatan dengan kawasan Pauh. Oleh itu lebih sesuai batuan sabak ini diletakkan sebagai bahagian teratas Formasi Mahang.
Kata kunci: sabak, Formasi Mahang, Bukit Tuntung, rijang, Formasi Kubang Pasu
