the Terumbu Limestone (Miocene), East Natuna Basin, South China Sea, Indonesia. AAPG Bull. 69, 2, p. 258
(Abstract only. Terumbu Lst reservoir 200 TCF (72% CO2), 1500 m of M-L Miocene platform-reef carbonates
with complex diagenetic history. Partial marine cementation and micritization in platform environments during
deposition. Freshwater diagenesis below subaerial unconformities within and at top Terumbu. Aragonitic
grains leached, pores partially cemented by low-Mg calcite. Pressure solution and cementation during burial to
~3,000m left minor porosity. Late burial leaching high-Mg calcite. Ferroan-calcite and dolomite cements line
pores and fluorite crystals occlude many pores. Whole-rock isotopes suggest high-T carbonate alteration. CO2
derived from dissolved Terumbu Lst. Fluoride-bearing hydrothermal fluids from granitic basement selectively
dissolved constituents in deeply buried Terumbu)
