| They represent coarse-grained precursor material that did not melt during chondre formation, and provide a tangible record of chondre precursor grains. |
| Several relatively large matrix spherules, about 0.1 to 0.3 mm across, are present as a bead-like girdle, band, or sheath inside the periphery of the chondre. |
| They are occasionally included in metal or troilite, and in one case, together with grains of metal and troilite, form a broken ring around a chondre. |
| chondre rims are commonly discontinuous and variable in thickness, and chondrules are often in contact with matrix materials directly. |
| The texture and mineralogy of a chondre reflects the nature and composition of its precursor material as well as its thermal history. |
