A high-resolution oxygen isotope record based on 356 measurements of conodont apatite
from several low latitudinal sections in South China, USA and Iran was composed in order to …

The preservation of bone or bioapatite over geologic time has presented paleobiologists
with long-standing and formidable questions. Namely, to elucidate the mechanisms …

Conodonts, microfossils composed of carbonate-fluor apatite, are abundant in Palaeozoic–
Triassic sediments and have a high potential to preserve primary oxygen isotope signals. In …

The crystallinity index (CI) is a measure of the percentage of crystalline material in a given
sample and it is also correlated to the degree of order within the crystals. In the literature two …

The purpose of this study was to test the hypothesis that mineral maturity and crystallinity
index are two different characteristics of bone mineral. To this end, Fourier transform infrared …

Carbonated apatites represent an important class of compounds encountered in many fields
including anthropology, archeology, geology, medicine and biomaterials engineering. They …

The reliable determination of bioapatite crystallinity is of great practical interest, as a proxy to
the physico-chemical and microstructural properties, and ultimately, to the integrity of bone …

Spectroscopic indicators of bone crystallinity such as the infrared splitting factor (IRSF) are
commonly used to determine the general state of preservation of ancient bone. In principle …

Diagenetic alteration may limit the potential use of the biogenic composition of fossil bone as
a reliable source of information for dietary, environmental and climatic reconstructions. One …

Crystallinity is related to the degree of order and the crystal size of a given crystalline
substance. It can affect the quality of hydroxyapatite (HA) and its abnormality can lead to …
