Good day dear Hive Community, first of all I would like to wish you a pleasant day and hope you are doing well and you were able to have some positive experiences! In this post, I would like to bring a mineral a little closer and hope you can expand your knowledge.
Here you can see photos of two different specimens of the mineral Olivenite, which is a rather rare mineral and belongs to the mineral class of vanadates, phosphates and arsenates. The mineral was first discovered in the 18th century in a mine in Cornwall in England, which has been one of the most important places for the mining of pewter since ancient times and a central place from where the pewter was shipped over the sea. Olivenite was then named in the 19th Century by the Scottish mineralogist Robert Jameson (1774 - 1854) who had named it after the olive green color and it was already known under other names before. It is usually found in the oxidation zone of copper-containing deposits and it is usually found together with other copper minerals such as azurite, cornwallite, malachite or chalcopyrite. The color can vary greatly and in addition to green specimens, you can also find yellow or white and interesting is that due to the influence of strong heat it can also lead to a change in color. In total, it has already been discovered at almost 500 locations and due to its rarity, it is not used as an ore for the extraction of copper and is particularly popular in collector circles and it is important to mention that it contains arsenic and therefore must always pay attention to the correct storage due to the toxic properties!
Thank you very much for stopping by and I hope you could learn something new about this interesting topic! I captured these pictures with my Camera Sony Alpha 6000 plus 55-210 mm lens!
