Normal style="MARGIN: 0cm 0cm 0pt; mso-pagination: widow-orphan; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto">Detailed field observations have revealed that the Damiao iron ore field obviously has excellent potential and is likely to become the largest base area of iron resources in China. New evidence supports neither the opinion that all the component igneous units in the Damiao anorthosite complex were evolutionary products of a unique primary magma nor the hypothesis that ore magma was responsible for the formation of the Damiao-type iron deposit. The anorthosite underwent at least two more times of deformation than the norite, suggesting that the norite was emplaced after the consolidation and cooling of the anorthosite. The generation of the Damiao type iron deposit is closely related to the noritic magma.
