Abstract
Gunung Paku near Klian Intan, Perak, located within the western Tin Belt of
Peninsular Malaysia, is a primary tin deposit in Malaysia mined since 200 years ago,
contributing 3–5% of tin ore concentrates previously, and recently over 70% of the
Malaysian tin. Gunung Paku is associated with biotite granite (184–230 Ma) of the
Main Range Granitoid which extends up to the southern part of Peninsular and Central
Thailand. The primary tin mineralization style at the Gunung Paku is mainly associated
with widespread occurrence of sheet‐like quartz veining systems parallel to the strike of
the host rocks and confined within a narrow N–S trending fault zone. The
mineralization formed within a thick sequence of metasedimentry rock that belongs to
the Baling Formation of Palaeozoic age. From the geological survey, Sungai Belimbing,
Sungai Air Jernih, Sungai Kepayang, Sungai Rui, Sungai Kuak, Sungai Hitam and
Sungai Duri are chosen for hydrogeochemistry characteristics of sediment and water.
The purpose is to know the effect of activities surrounding to the stream sediment and
water quality. Representative samples are subjected to several test such as X-ray
fluorescence, X-ray diffraction and Inductively Coupled Plasma. From the XRF
analysis, the stream soil sediment from the stream surrounding Gunung Paku shown that
the composition of metal is low except element of Al and Fe. The analysis of ICP show
that the concentrations of metals for B1, B2 and B3 are high cause of activities
surrounding compared with other water samples and also the lowest of pH values and
the highest of electrical conductivity.
