GEOLOGICAL PHENOMENON – PEDRAS PARIDEIRAS (PROCREATING STONES)

by Antonio Gil February. 27, 2016 3587 views

This geological phenomenon has turned Arouca into a unique attraction. The “pedras parideiras” (procreating stones) “give birth to” other stones. They are found on Freita Mountain, near Castanheira. It's hard a literal translation of the name of these stones, but explaining the phenomenon becomes easier to understand. This is a rare phenomenon in the world. And is why it is so famous. When there wasn’t an explanation, maybe people thought it was magic, a work of the Gods or Devil, but today it is a scientifically explainable phenomenon.. These stones are granite rocks with numerous golden nodules that, with a specific temperature, pop out from its rock “mother” and fall on the surrounding floor. Therefore, people from Castanheira called them something like stones/rocks which give birth. A popular legend attributes magical properties to these nodules in terms of female fertility, since these dark mineral lumps pop out spontaneously from a creamy-coloured matrix due to differential dilatation during hot weather.

This is a very rare phenomenon that only takes place here, in Portugal, and near St. Petersburg in Russia

Wow, Antonio, I like stuff like this. In a place called Formby sands they find footsteps that appear and then only stay for a few weeks and these are said to be Neolithic footprints, bit freaky. Would love to see these rocks.
