Although at first glance these menilitos not have a great mineralogical importance to collectors and ways they may not be to the liking of the majority, they are not without a certain mystery, mainly due to the various forms and bumps that make them up, maximum interest if fits for them, being in archaeological sites of our ancestors and used in their culture.
This work can be found in the study by Molina and María Asunción in Jerónimo Molina called NATURAL STONE IDOLS IN MAINLAND SOUTHEAST BRONZE and partly in this abbreviated summary, oxendales it seemed interesting to learn these is based more enigmatic oxendales pieces.
Its rounded appearance because in the process of training, diatomite have been deposited by filling cavities. However, not all adopt that way, as there are pieces of opal flat appearance. And interestingly in those flat aspect quite da crystallization. Keep in mind that what we see is not the opal, but a hardened layer of diatomite. If you scrape or grind the white layer underneath opal comes true, of gray or black.
Some of them, perhaps due to their circumstances training, come to crystallize inside, with a shiny appearance similar to some flint, of which opal is the cousin.
Materials found in lacustrine character belonging to upper Miocene and are a product from gel deposition thermal waters, oxendales being in primary form as nodules forming concretions in these rocks. Collection area menilitos opals must also cite a research made by the Mining Museum in 1999 and has put frontline research these regions Hellin and Elche de la Sierra, the importance of the findings of fossil fish- and the most common messinienses diatomite formations located in the upper Miocene oxendales and the study of stratigraphy are the reference of these paleontological studies showing the Iberian paleoictiológico registration.

Very close to the town of Agramón (Albacete) and in the region of the valley is Hellin reservoir Cliques, found these diatomite deposits that were formed in large basins lagoon origin. Diatomite is a sedimentary rock composed essentially scum buildup unicellular aquatic plants (diatoms) consolidated by a sludge composed mainly of silica (opal). Opal is often a fosilizador element of animals and plants. Opals menilitos oxendales More about the sedimentary rock called fancy shapes oxendales of idols or opals menilitos
Their presence reveals the existence in the past of those large shallow lagoon basins. Al menilito opal is given the name of "natural idol" or "little idol" because many resemble figures, the head is a minor bump in the trunk in two, and chest and abdomen oxendales in three neck and waist. Its height ranges from 8 cm being of usually 3-5 cm. In some specimens encrusted gastropod oxendales fossils appear as turritellas. Opal and turritellas menilito both pictured above and below the fossils oxendales we see, turritellas, aquatic gastropod mollusk and living on the seabed, was very abundant in the Eocene period 55 ma to 34 ma Cenozoic Era. These fossil remains oxendales in most cases can be seen with the naked eye or with the aid of a pocket magnifier. Wonderful example of menilito opal and fossils Turritellas.
It is natural idols of stone found in deposits Enolíticos that have barely been touched up and are in their natural state, only the most salient parts of the bumps thinning is observed due to the natural friction oxendales of use, in any case you will note a certain retouching to simulate a nose or a dimpling to simulate the eyes; come from diver
