The only areas that are likely to have furnished the original stone for the Colossi of Memnon are near Cairo (Gebel el Ahmar), Aswan, and possibly Silsileh. Neutron activation analysis of samples from the colossi shows them to be distinctly different from samples obtained from the three known quarries near Aswan and from the quarries near Silsileh and Edfu, but very similar to samples obtained from Gebel el Ahmar. Petrographic analysis of colossi and quarry samples also provides strong evidence that the colossi came from Gebel el Ahmar. The blocks used by the engineers of Septimius Severus to reconstruct the north colossus were shown by neutron activation analysis to have originated from a deposit other than Gebel el Ahmar. The composition of these blocks conformed with samples taken from the quarries 8 and 9 km north of Edfu (the quartzite deposit closest to Thebes) and from the Aswan quarries. Petrographic analysis associated these reconstruction blocks with Edfu but not with Aswan. Neutron activation analysis of other artifacts in the area of the colossi indicates that they also came from Cairo rather than Aswan.
唯一有可能为门农巨像提供原始石材的地区是开罗（盖贝埃尔阿马尔山）、阿斯旺，可能还有锡斯利勒。对巨像样本的中子活化分析表明，它们与从阿斯旺附近的三个已知采石场以及锡斯利勒和艾德夫附近的采石场获得的样本明显不同，但与从盖贝埃尔阿马尔山获得的样本非常相似。对巨像和采石场样本的岩相分析也提供了强有力的证据，证明巨像来自盖贝埃尔阿马尔山。塞普提米乌斯·塞维鲁的工程师用来重建北巨像的石块，经中子活化分析表明，它们的来源并非盖贝埃尔阿马尔山。这些石块的成分与从距埃德夫 8 至 9 公里处（最接近底比斯的石英岩矿床）的采石场和阿斯旺采石场采集的样本相符。岩相分析将这些重建石块与埃德夫联系起来，而不是与阿斯旺。对巨像区域的其他文物的中子活化分析表明，它们也来自开罗，而不是阿斯旺。
