I'm looking for mineralogical information on that ubiquitous stone called "blue bit" (aka "blue bitch") rock. For instance, is it igneous or metamorphic? What is its composition? Other properties? etc. I've googled but just find links to homes that include walls or features made of this local stone.

Thanks--

Try calling VI Cement Co at 775-0605 who may be able to either give you information or put you in touch with local masons who use it. It's locally called, "Blue Bitch!"

Jules: There is an excellent book: "Island Peak To Coral Reef: A Field Guide to the Plant and Marine Communities of the Virgin Islands" put out by UVI and the Cooperative Extension Service. The section on geological history indicates that melted volcanic material cooled to form the oldest igneous rocks. They have pictures of what they call "blue beach" from the Louisenhoj Formation. The article by Roy Watlington of UVI also indicates that Thomas W. Donnelly was one of the original researchers who concentrated on St Thomas and St John. He also mentions Denis K. Hubbard and Douglas Rankin as working in this area. I would think the UVI library would be a good place to research, if you are on island.
