BariciteA rare member of the Vivianite family of phosphate minerals (see http://bit.ly/2nqydbX for more on this group) its translucent colour ranges from hueless to light blue. So far it has only been found in two places, near the Big Fish River in Canada’s Yukon Territory (the type locality, from which it was first described) and in the northern regions of New Zealand’s South Island near Malborough, also a major terroir for excellent wines. A recent discovery, it was named after a Croatian mineralogist in 1976. The mineral is very soft, a mere 1.5-2 on Mohs scratch hardness scale and occurs as thin flakes organised in books, with a habit a bit like that of the mica family that grow infilling cracks in rocks rich in Siderite, and iron carbonate in one locale and in a raised beach in another. This specimen was mined in Canada, sits on a quartz matrix, and measures 4.0 x 4.0 x 2.5 cmLozImage credit: Rob Lavinsky/iRocks.comhttps://www.mindat.org/min-524.htmlhttp://bit.ly/2eRrCcd -- source link
