Abstract

Detailed petrographic and geochemical studies had been done to 89 samples from the Chuping Formation collected at Bukit Tengku Lembu area. The aim of this paper is to document the nature of dolomitization and its petrographical characteristics. Two types of dolomites have been recognized; stratified dolomites and non-stratified dolomites. Non-stratified dolomites can be further divided into complete-replacing dolomites, individual-scattered dolomites and selective-replacing dolomites. The geochemical data from X-ray Fluorescence analysis detected low concentrations of trace elements which includes Al, Fe, K, Mn, Na, P, Si, Sr and Ti, with a high Ca/Mg ratio ranging from1.681 mol to as high as 106.942 mol. This big fluctuation in values indicates a variation of fluids that are involved in the diagenetic processes. Individual-scattered dolomites have perfect rhombus shape with no evidence of being affected by compaction and pressure indicating a shallow burial setting. Meanwhile presence of perfect saddle dolomites with replacive nature and no signs of being affected by compaction, also suggested late burial settings, in which compaction ceased. High Ca/Mg ratios may also suggest some dedolomitization effects.
