Little Britain Township, Lancaster County, Pennsylvania

摘要

Wood's chrome mine operated primarily from 1828 to 1881, when the main lode was exhausted; it has produced very few good specimens since then, and yet it is still well-known among many mineral collectors as one of America's early classic localities. It yielded the world's finest examples of brucite in the 1860s, and was also well-known in its day for emerald-green zaratite, and reddish purple "kammererite," the Cr-rich variety of clinochlore. The mine is also the co-type locality for dozyite.
