“…Carbonate sedimentation started sometime in the late Eocene and expanded in the Oligocene when intensive subsidence introduced transgression of the basin. According to subsurface seismic survey in the southwestern part of the NEJB, the distribution of the carbonate lithofacies is controlled by segmentation of the basement related with the extensional fault systems trending northeast‐southwest (van‐Simaeys, Musgrove, Stephens, Weidmer, & Zeiza, ). A carbonate platform that forms important hydrocarbon fields developed in southern part of the NEJP, in which: (i) pinnacle reefs in the inner platform; and (ii) barrier reefs along the shelf edge were formed (Figure b; Satyana & Djumlati, ).…”

“…Recent studies on the isolated platform (Hakiki, Sekti, Simo, Fullmer, & Musgrove, ; Sharaf, BouDagher‐Fadel, Simo, & Carroll, ; Sharaf, Simo, Carroll, & Shields, ; Simo et al, ; White et al, ) showed that development of the carbonate platform was also influenced by relative sea level changes including a significant drop in sea level at the Oligo‐Miocene boundary, called the Mi‐1 event related with Antarctic ice‐volume expansion (Paul, Zachos, Flower, & Tripati, ; Zachos, Shackleton, Revenaugh, Pälike, & Flower, ). The global drop in sea level also resulted in diagenetic alteration of the carbonate sediments in the NEJB (Hakiki, Musgrove, Varnai, Ditya, & Sapardina, ; van‐Simaeys et al, ; Zeiza, van‐Simaeys, Musgrove, Sekti, & Hakiki, ), potentially influencing the petrophysical properties of the carbonate reservoir.…”

Depositional and diagenetic history of limestones and dolostones of the Oligo‐Miocene Kujung Formation in the Northeast Java Basin, Indonesia

Lithological and geochemical features of platformal carbonates record the signatures of the global climates and the regional environmental settings and also reconstruct the diagenetic history and porosity evolution, which are essential to evaluate the potential of hydrocarbon reservoirs. This study investigates the platformal carbonates of the Oligo-Miocene Krunji Formation of North East Java Basin, which are potentially significant hydrocarbon reservoirs. The carbonate sequence in a 283 m thick section at Kranji in East Java is subdivided into three lithological units: limestone unit 1, dolostone unit 2, and limestone unit 3, in ascending order. The strontium-isotope ratios of well-preserved calcite samples indicate the depositional period from Chattian (late Oligocene) to Burdigalian (early Miocene), which is consistent with ages of the foraminifer assemblages. Unit 1 consists of low-porosity limestone, in which two horizons of subaerial exposure are recognized by the occurrence of red-colored matrix and lower δ 13 C values. Unit 2 consists of dolomitic rock and exhibits coarse-grained calcitic grains and cross-stratified structure. Considering that this unit has been subject to dolomitization, the sediment of unit 2 was initially permeable and was likely deposited in a shoal setting. The overlying unit 3 of Aquitanian-Burdigalian age is characterized by a highly granular texture. High porosity and uniformly low δ 13 C and δ 18 O values indicate that Unit 3 was subjected to more intense meteoric diagenesis than the Chattian unit 1. This was likely a consequence of the Antarctic ice-sheet expansion during the Oligocene/Miocene transition, which amplified sea level change. The unit 2 dolomite has high δ 13 C and δ 18 O values and a high 87 Sr/ 86 Sr ratio which resulted from the reflux of seawater into permeable the sediment body in middle-late Miocene (Burdigalian Tortonian) following the deposition of unit 3. The porosity and permeability of the Kujung Formation were initially controlled by sedimentological processes, but largely modified by later diagenetic processes.

Cenozoic Isolated Carbonate Platforms—Focus Southeast Asia

View full text Add to dashboard Cite

In Southeast Asia, Cenozoic carbonates commonly were initiated or terminated at times of tectonic change, and they are bound by unconformities. A review of the timing of several of the largest unconformities shows they correlate over wide areas. These unconformities divide the stratigraphic record of Sundaland into episodes, with times of rapid basinal re-adjustment separated by periods of relative stasis. These generalizations are true not only in the successions deposited during the dominantly extensional later Eocene to early Miocene, but also in the often-compressional middle Miocene and younger deposits, in which at least three phases of rapid tectonic and stratigraphic change can be correlated over multiple depocenters. A detailed review of many areas of Southeast Asia using quantitative biostratigraphic methods indicates that tectonism resulted in relative changes in sea level, with no indication that eustasy was an important driving force. The boundaries between these sedimentary episodes vary in their effect and distribution, depending upon the tectonic cause. As a consequence, there is no uniform subdivision of the stratigraphic record across the region, which precludes a simple Sundaland-wide classification of primary sedimentary sequences. This review concentrates on both event timing and rates of change within and between basins, especially those changes that initiated or terminated carbonate deposition. In addition, some short-lived carbonate buildups that developed during transitional periods are described. This review provides the beginnings of a new stratigraphic framework for the Cenozoic carbonates and related deposits of Southeast Asia. It requires an inductive analytical methodology, in contrast to the model-driven and deductive approaches that have been applied in recent years. This episodic stratigraphy approach includes integration of large amounts of analytical data, for which the Cenozoic tropical sediments of Southeast Asian basins are particularly well suited.
