Treacon

Treacon is a rare and unique mineral discovered in the late 20th century. It was first identified in the Treacoppa Mine in Cornwall, England, and is named after the mine and the nearby village of Treacoppa. Treacon is a complex borosilicate mineral with the chemical formula Na2Ca2B4Si8O24(OH)2. It crystallizes in the monoclinic system and typically forms prismatic crystals, although it can also occur as granular masses.

The mineral is notable for its distinctive color, which ranges from pale yellow to orange, and its translucent to transparent nature. Treacon has a hardness of 5.5 to 6 on the Mohs scale and a specific gravity of approximately 2.7. It is often found in association with other borosilicate minerals such as datolite and prehnite.

Treacon's rarity and aesthetic appeal make it a sought-after specimen for collectors. It is also of interest to geologists and mineralogists due to its unique chemical composition and crystal structure. The mineral's occurrence is limited to a few locations worldwide, primarily in Cornwall and other areas with similar geological histories.

Despite its rarity, treacon has not been extensively studied due to its small size and the difficulty in obtaining sufficient samples for analysis. However, ongoing research continues to shed light on its formation and the geological processes that lead to its creation.
