Mount Jerai is a 1,217- metre tall
inselberg located near the coast of the
Strait of Malacca, and is part of an eponymous geological formation that correlates with the Matchinchang Formation in the island of
Langkawi. The Jerai Formation is originally a
sedimentary formation composed of fully
metamorphosed sandstone and
shale, and it consists of
argillite,
arenite and
porphyry facies.
Insular origins There is an information board on top of the mountain stating that it used to be an island called Pulai Serai before the sea levels receded letting it form a mountain. This is probably supported by
I Ching's record of Pu Lou Shi (Pulau Sri), a country located west of Sribogha. ==Tourism==
