位于埃及东部沙漠的克劳迪亚诺斯是制作罗马柱子的花岗闪长岩的重要来源。采石场1119个磁化率测量的计算机等高线显示出系统的变化，采石区西部的读数较低，东部的读数较高。使用基于t检验的程序，对罗马及其周围地区的62根蒙斯Claudianus柱的170个测量值与采石场的读数进行比较。一些磁化率明显低或高的柱子可以非常精确地出现在克劳迪亚蒙斯9平方公里范围内约700×700m的区域。敏感度在Mons Claudianus范围中间的柱子不能被准确地确定来源。结果表明，早期(公元1世纪)蒙斯克劳迪亚诺的西部和东部都使用了采石场的几个部分，而不是有系统地或连续地开放该地区。在公元3世纪的纪念碑中发现的柱子，与早期材料起源于蒙斯克劳迪亚诺的相同部分，可能表明在一些纪念碑中重复使用了柱子。磁化率是一种便携式和非破坏性的方法，不仅能够对采石场进行起源，而且能够对单个采石场内的特定区域进行起源。
Mons Claudianus in the Eastern Desert of Egypt was an important source of granodiorite for Roman columns. Computer contouring of 1119 magnetic susceptibility measurements at the quarry shows systematic variations, with low readings in the west of the quarry area and higher readings in the east. One hundred and seventy measurements on 62 columns of Mons Claudianus type in Rome and its environs were compared with the quarry readings, using a t-test based procedure. Some columns with distinctively low or high magnetic susceptibility could be provenanced very precisely to areas of about 700 × 700m within the 9km2 of Mons Claudianus. Columns with susceptibility in the middle of the Mons Claudianus range could not be provenanced precisely. Results indicate early (first century AD) use of both west and east parts of Mons Claudianus, and contemporaneous use of several parts of the quarry, rather than systematic or sequential opening of the area. Columns found in third-century AD monuments, provenanced to the same parts of Mons Claudianus as earlier material, may indicate reuse of columns in some monuments. Magnetic susceptibility constitutes a portable and non-destructive method capable of provenancing not only to a quarry, but to specific areas within a single quarry.
