Abstract

Meerschaum (sepiolite), believed to be the first reported occurrence in Malay­ sia, is studied by chemical, DTA, optical and X-ray methods. It occurs as a white fibrous mineral in the forms of stringers, veins and films along irregular fractures in the marble host rock from an abandoned quarry. Although meerschaum is a high value industrial mineral, used for making smoking pipes and cigarette holders, this occurrence is too small to warrant any serious investigation. However, the quarry operators in the area should be made known ofits possible economic importance for two reasons. Firstly big veins may be profitably exploited. Secondly it is a source of magnesium contamination for high-calcium limestone users. The reported meerschaum is believed to be formed by hydrothermal activity.
