Metallic tubes from St-Jean-de-Livet

In 1968, the speleologists Y Druet and H Salfati claimed to have discovered a number of semi-ovoid metallic tubes they believed to be artificial in Cretaceous (Aptian) chalk at a quarry in St-Jean de Livet (Calvados, France), which they announced in a letter to the editors of Planète, a French magazine devoted to unsolved mysteries. The tubes were shaped identically, but their sizes varied between 30 and 90 mm in length, and 10 and 40 mm in width (Druet & Salfati 1969, 22). According to the authors of the letter (dated 30 September 1968), the objects were currently being studied by the Geomorphology Laboratory of the Université de Caen, but nothing further seems to be known about them. Several requests by the author for further information from the Department have failed to produce a response; Cremo and Thompson, in Forbidden Archeology state that they have had a similar lack of answer. Perhaps the Department has no records; perhaps staff are fed up with requests for information on something they either never dealt with or dealt with so long ago that none of the present staff has any knowledge about.

  1. He, I remember these type of thing from another case. They turned out to be some sort of natural mineralization thingy. Apparently, its not unique for iron or iron rich minerals to form in thick tube like structures.

  2. I have seen similar metallic tubes myself in very old stone formations, specifically atop the canyon walls at Chaco Canyon National Monument in New Mexico. My understanding is that these particular formations are the result of mineralization of ancient boreholes left by marine tube worms on the sea floor. Given that these tubes at St-Jean de Livet were found in a Cretaceous deposit, I would favor a similar explanation over any sort of artificiality. Furthermore, the fact that they are of different sizes but identical shape is consistent with such an explanation – a population of worms with different ages may have different sizes, but would likely have all had similar morphology.
