Damiao anorthosite complex, located at northern edge of the North China Craton, Chengde Hebei province, contains typical anorthosite–norite–mangerite association, and hosts abundant Fe–Ti–P oxide ores, and numerous geological, petrological and geochemical studies are available. However, ore-controlling structures analyses, tectonic stress field study and ore-forecasting model are poorly constrained, which are useful and critical to guide to further ore-prospecting. Damiao, Heishan, Maying, and Luoguozigou ore areas have been gradually discovered in the Damiao complex with middle to larger size ore-reservoir since 1928, all of which show typical magma type deposits. Field observation showed that the emplacement of the complex were controlled by EW-trending Damiao-Hongshilazi fault zones in south and Longhua-Pingquan fault zone in north, and iron ore-areas and ore-bodies within the complex were control by both NE and NW-trending faults. Nearly NS-trending fault formed and activated later than the mineralization, which cut and moved ore bodies. In the Heishan area, ore-bearing norite veins intruded into the consolidated anorthosite along conjugated joints. The occurance of joints and ore-bearing norite veins were detailed measured in the field and statistical results showed that the injection of ore-bearing norites during the metallogenic stage was mainly controlled by regional NS-trending compressional stress. SHRIMP dating of zircon, contact relations of different lithologies with ore-bodies in the complex, ore-controlling structures and ore-formation characteristics suggested that the process of magma intrusion and mineralization could be divided into three stages. Anorthosite magma most firstly intruded into pre-Cambrian gneiss at about 1.7Ga, and no mineralization took placed in this stage. During the second stage, norite magma intruded accompanied with the early stage mineralization, forming crystal-fractionation to protomagmatic deposits. And then, massive pegmatoid norite injected into anorthosite and earlier norite, forming differentiation to injection type iron bodies. The ore-forecasting model was finally established and favorable ore-prospecting areas were proposed, including the depth in the Heishan and Damiao, the northern and eastern parts of the Heishan, and the eastern edge of the complex probably covered by Mesozoic rocks, indicating that the ore-reservoir of the deposit should be very large in scale.
