View Full Version : Magnesite and Howlite

18-12-2009, 23:26
I picked up a crystal book the other day and it seemed to imply that magnesite and howlite were the same thing. I know that when they are tumbled, they do look remarkably alike, but I always assumed their chemical makeup was different. Anyone here know?

Well, according to Wikipedia:

"Howlite, a calcium borosilicate hydroxide (Ca2B5SiO9(OH)5), is a silicate mineral found in evaporite deposites."

"Magnesite is magnesium carbonate, MgCO3. Iron (as Fe2+) substitutes for magnesium (Mg) with a complete solution series with siderite, FeCO3. Calcium, manganese, cobalt, and nickel may also occur in small amounts."

So I guess they are chemically different!
