#### 3.5.3 Maps of Elements
An analysis of the mechanical properties was not made, because the study focused on the chemical composition, the existence of crystalline structures and the arrangement of the compounds in chondrule-shaped agglomerations. The maps of the elements on a second area of the powder of the P1 sample, denoted as P1-Ch2, shows the arrangement of elements indicating carbonates (CaCO\({}_{3}\)), sulfates (mainly CaSO\({}_{4}\), and possibly MgSO\({}_{4}\), FeSO\({}_{4}\) and Al\({}_{2}\)(SO\({}_{4}\))\({}_{3}\)), carbon in organics, sulfur in organics, a large number of chondrules containing silicon oxide and aluminum (SiO\({}_{2}\)/Al), as well as a very low content in Fe and Ni. In addition to the granular structures, this area studied at SEM on the P1 fragment powder shows porous structures associated with carbon (according to mapping), which is part of the organic type IOM (insoluble organic material), or fullerene C60. In fact, a transparent strand of what is identified as a fullerene individual sheet is seen at the bottom of the image [34]. A third area of P1 powder sample, identified as P1-Ch3, is denoted by the maps of element content of sulfates (CaSO\({}_{4}\)) and calcium oxide (CaO), as well as some calcium carbonate (CaCO\({}_{3}\)) in a crystalline state. The calcium carbonate in the calcite grains may be assigned to Techilinite due to the content in sulfur evidenced in the same area. Transparent sheet observed in the SEM image is assigned to individual fullerene sheets, fullerene C60 being evidenced by the FTIR spectra (Figure 2) similar to graphene transparent sheets, evidenced by [PERSON] et al. [34], on the SEM images of synthesized graphene few-layered sheets. The carbon in the organics with sulfur is also observed on the maps of elements of the P1-Ch3 area of the sample. Grains of chondrules with SiO\({}_{2}\) in a crystalline state are evidenced in CAIs. Finely dispersed silicon may be assigned to phyllosilicates organized in parallel sheets as [Si\({}_{2}\)O\({}_{52}\)-]n. Finely dispersed Fe-Ni and Mn particles are also observed. On the maps of the P2-Ch1 area of the powder sample from fragment P2, the elements calcium (Ca), carbon (C), oxygen (O) and sulfur are assigned to oxide, carbonate and sulfate (CaO\({}_{2}\), CaCO\({}_{3}\) and CaCO\({}_{4}\)). Calcium is also assigned to CAIs and carbon is also assigned to organics with sulfur (sulfones). Grains of SiO\({}_{2}\) metallic iron (Fe) chondrules, and also finely dispersed Fe-Ni particles, are noticed. Thorium (Th) is assigned to thorium oxides. The SEM image of this area shows the structures with good mechanical strength, practically those structures, such as chondrules. The second studied area on the powder sample of fragment P2, denoted as P2-Ch2, shows, based on the maps of elements corroborated with the FTIR spectrum, carbon (C) in organic compounds and organic compounds with sulfur. The veins of calcium carbonate (CaCO\({}_{3}\)) and grains of CaCO\({}_{3}\) assigned to calcites in techilinite, due to sulfur observed, are evidenced by the maps of the elements. However, it is obvious that sulfur areas overlap the carbon areas in an almost identical pattern, indicating that the majority of the sulfur is an organic bond. Chondrules with a content of silicon oxide (SiO\({}_{2}\)), magnesium (Mg), aluminum (Al), manganese (Mn) and Fe-Ni particles are observed by element arrangements in the maps. The SEM image of this area shows less brittle carbon structures than the material as a whole, but with a tendency to crack following the mechanical stress to which it was subjected.
