Abstract

Isolated carbonate platforms are abundant and widespread in Cenozoic strata and in the present-day oceans of Southeast Asia. The purposes of this article are (1) to describe the basic oceanographic setting of present-day Southeast Asia oceans; (2) to synthesize, compare, and contrast observations of the character of extant platforms in the context of fundamental oceanographic controls; and (3) to leverage these insights to develop a more complete understanding of older isolated platforms, especially the Miocene systems of Central Luconia. The data, presented to mimic an offshore-to-nearshore transect, illustrate Holocene platforms with a spectrum of sizes, depositional relief, facies abundances, and water depths. Although the first-order patterns of relief, size, and orientation are controlled by the geologic setting and Pleistocene history, the results demonstrate the influences of physical processes (waves, tides, currents), siliciclastic sediment, and chemical oceanography (nutrients, salinity, temperature) on the sedimentologic and geomorphic character of these platforms. Careful and critical application of these concepts to Central Luconia reservoirs in isolated carbonate platforms provides actualistic examples and process-response analogs. Although these perspectives offer understanding into controls on horizontal and vertical reservoir heterogeneities, they also emphasize that any one modern system can only be a partial analog for an ancient reservoir in an isolated carbonate platform.
