With reference to recognition by P. C. Aw of the Temangan dike as an ignimbrite (see this Bibliography Vol. 31, No. 8, 10 E67-07201), it is pointed out that rocks mapped as quartz porphyry in other Malayan localities are probably also ignimbrites. The fissure in which the Temangan dike is located is considered part of a major structural element which may be a wrench fault.
