Geology of Southeast Langkawi

I.folIDd the recent note by Wong et al. (1973) of great interest' . and . I would like to congratulate the authors on clari - . fying, in.particular, the geology of Pulau Tuba and the adjacent islets. . .1' agree with their conclusions reganling the strati­graphy but I question their interpretation of the structure.

Two parties of students from the thiversity of Malaya and nwself nappe9. Pulau Tuba in October 1962 and August 1963. The results of the! napping in the southe 'Stem part of the island are shown in Fig. 1. On the second visit we noted three 1ine­stone nasses lyjng southeast of the Silurian 1inestone of W:>ng et ale (1973, fig. 2).

One of these forms a small hill near the eastern edge of the alluvial tract in the east centrel part of the island (A on Fig. 1). The other two (B and C on Fig. 1) outcrop north of Tanjong Rami on the hillside which overlooks Te10k Berembang. These linestones were marnorized and as far as we could see contained no fossils. Their netanorphism was at least partly thernal. since small granite bodies and quartz-tounnaline veins are fotmd within the sedinentary rocks fonning southeast Pulau Tu1:a. The limestone at A is flow folded , stylolitic, and dips eastward. In lithology it resembles the lower Palaeozoic Setul. linestone exposed on the coast of Pulau langkawl. southeast of Kuah (Hutchison 1963). The JJDI'e southerly linestones outcropping at B and C have a lithology similar to that of the Permian Chuping Ur-:estone. They apPear to dip gently southwest but this nay be due to slipping on the steep hillside. Their relationship to the adjaceIlt sandstones and shales is tmc1ear although, at its south­we'stem end, linestone C forms a cliff backing a foreshore of black silty shales.

The well-bedded quartzites exposed along the shore south of Tanjong Peluru (Unnamed Devonian formation of Wong et.al. 1973) resemble the late Devonian rocks of Pulau Rebak Besar and Pulau langgtm. They rray be included within the "Rebanggtm Beds" .

These dates are in close agreement anDng themselves, and help tc finnly establish thE! contenponmtdty.ofthe, 3 IIe:ter notch throughout the area. This agrees ~ll with a"date of, 5200' + 200 y.b.p. contained on shell natecial from the 3 mater level at'BuJd.t Chuping,. '4-nthe, 'central part of Perlisabout 12 miles inland from the sea (Alexander" 1962). The shells from Pulau Langglm and Bukit Papan were collected from the inner part: of the notch, and show that, nOtch formation , ceased about 5 to 6 thousand years before the present, when ,sea waters withdrew. 1m age of 2590 + 100 y.b.p.was obtd..ned by Tjia and others (1972) from oysters at-a lpcality on Pulau Blmting near the third locality of this 'I'ep:>rt. The .... 2590+ 100 y.b.p. date is from a horizon 1.5 to l.8 neters above mean sea'level, 'Which is below tJ:te level of the oysters dated here, and represents a later and lower sea level stand.

, The dates obtained from oysters associated with the3,neter notch in northwest peninsular Malaysia are .natched·· bY indidations of a 3 ueter shoreline on the eastern coast of the peninsula (Pitch, 1952), and by radiocarbon dates of 5270 + 110 y.b.p. and 5460 + 110 y.b.p. from a H::>locene suJ:mergence on the Tarnbelan Islands, on-the Sunda Shelf off the east coast of peninsular Malaysia (Haile, 1970 a, b; Haile, in press). Taken together, these severe! results pre­sent Convincing evidence that about 5 to 6. thousand years ago sea level was about 3'JIeters higher than present .sea levelovel' 1IllCh of the Sundaland block. This appears to result from absolute changes in sea level :rather than from relative changes in shorelines caused by local tectonic events.
