“…3) of samples after the reaction between calcite and diammonium hydrogenphosphate showed that the products were aligned in a particular direction. As reported by Jin et al [12], although the oxygen atoms on the ideal (1 01 4) plane were all aligned in a plane, alternate oxygen rows in a diagonal direction extended further out of plane in relation to the remaining oxygen rows. This is demonstrated in Fig.…”

A calcite surface reacted with phosphoric acid or phosphate in the initial stage was analyzed under an atomic force microscopy (AFM). The cleaved calcite was immersed in phosphoric acid or diammonium hydrogenphosphate under various conditions. The calcite dissolved upon immersion in phosphoric acid and many pits, oriented in a particular direction, were observed on the calcite surface. When the calcite was immersed in diammonium hydrogenphosphate, reaction products, also aligned in a particular direction, were observed on the calcite surface. X-ray diffraction analysis revealed that these products are carbonate-containing hydroxyapatite.

“…Sometimes, the height difference leads to the impression of paired rows, which is the origin of the notation 'row paring'. The finding of Rachlin et al has been reproduced in consecutive experiments by Stipp et al [20] and Jin et al [19] using contact AFM in liquid and atmospheric environment, by Rode et al [17] using NC-AFM in a liquid environment and by Schütte et al [16] using NC-AFM under ultra-high vacuum (UHV) conditions. In contrast, the row-pairing reconstruction has neither been observed in experiments by Fenter et al [14] using x-ray reflectivity and by Geissbühler et al [13] using x-ray scattering in a liquid environment, nor by Magdans et al [15] using GIXRD in N 2 and humid atmosphere.…”

“…In contrast, a similarly detailed discussion on the existence of the row-pairing reconstruction is lacking in the literature. This might be due to the fact that this reconstruction is virtually omnipresent in AFM studies [18,20,19,17,16,42,21]. However, as the argument regarding this reconstruction is based solely on AFM data, it is worthwhile to initiate a critical discussion of the existence of the row-pairing reconstruction.…”

“…The current description of each of these two reconstructions is separately depicted in figure 2. The models follow work performed by Rohl et al [24] for the (2 × 1) reconstruction and by Jin et al [19] for the row pairing. In addition to these surface reconstructions, intense relaxations involving atom displacements and carbonate group rotation within the upper atomic layers have been revealed by both theoretical investigations [23,25,24] as well as experimental studies [15,14,13].…”

“…When using the AFM technique for atomic-resolution imaging, usually two sites of maximum interaction are observed inside the calcite (1 × 1) unit cell [21,16,19,20,18,17,22]. When considering the (2 × 1) reconstruction, the primitive surface unit cell doubles in size and, therefore, a total of four sites of maximum interaction are usually observed.…”

Calcite, the most stable polymorph of calcium carbonate, is one of the most abundant simple salts in the geological environment. Consequently, its natural (1014) cleavage plane has been studied extensively by a wide range of surface-sensitive techniques, giving indications for two reconstructions, namely a (2 × 1) and a so-called 'row-pairing' reconstruction. The existence of the (2 × 1) reconstruction has been discussed controversially in the literature, but is now confirmed as a true surface property. In contrast, a comprehensive discussion on the existence of the row-pairing reconstruction is lacking so far.Here, we present a non-contact atomic force microscopy (NC-AFM) study of the (1014) calcite surface performed in an ultra-high vacuum. We discuss a broad variety of different NC-AFM contrasts and present a comprehensive classification scheme. This scheme encompasses a total of 12 different contrast modes. Atomically resolved NC-AFM images are shown, giving experimental evidence for 10 of these contrast modes. In particular, some of these modes allow for identification of the two surface reconstructions while others do not. This variety in appearances provides an explanation for the seemingly contradicting observations in the literature. Based on a detailed investigation of the influence of tip termination and interaction regime, we further analyse the existence of the row-pairing reconstruction.
