  abstract = {{T}ridacnidae shells, a valuable archive of past environments, are common in the {B}alobok {R}ockshelter archaeological site on {S}anga-{S}anga {I}sland in the south {P}hilippines. {T}his site was occupied during the mid-{H}olocene (ca. 5000-8800 {C}-14 yr {B}.{P}.), a period of {N}eolithic cultural expansion in the {P}hilippines. {T}his paper focuses on the preservation of two shell specimens, {H}ippopus hippopus and {T}ridacna maxima, unearthed from two mid-{H}olocene layers within the rockshelter. {T}he shells' mineralogy and microstructure (prismatic and crossed-lamellar) were studied using micro-{F}ourier transform infrared spectroscopy and scanning electron microscopy to determine if the samples were suitable as paleoenvironmental records. {B}oth shells are still aragonitic but aragonite crystals of both microstructure types are partly dissolved. {T}his dissolution, characteristic of meteoric water alteration, precludes their utility in paleoenvironmental geochemical studies. {N}evertheless, these shells are abundant in archaeological sites in the region and may be better preserved in other depositional contexts; more studies on {P}hilippine {T}ridacnidae shell diagenesis are needed.},
